World number one Novak Djokovic is in favour of technology replacing linespeople across the ATP Tour amid the absence of judges at the Australian Open.
This year's Australian Open is being held without line judges as a response to coronavirus restrictions at Melbourne Park, where "Hawk-Eye Live" technology is being used on every court.
It is the first grand slam to replace all linespeople with technology as the tournament seeks to limit the number of people on court amid the COVID-19 pandemic.
Djokovic was sensationally disqualified in the fourth round of last year's US Open for inadvertently hitting a ball at a line judge during his clash with Pablo Carreno Busta in New York.
Asked about the situation at the Australian Open, defending champion and eight-time winner Djokovic told reporters: "I think back [at the] US Open last year, someone asked me whether I would support the idea of introducing this kind of line call technology at every tournament.
"Obviously providing that the tournament is able to afford financially that kind of investment, because obviously it is an investment.
"I said that I support that, because I feel, yes, I understand that there is a tradition and history and the way we kind of got used to the line umpires being there, and I think it's nice that there is a lot of people and also volunteers with these line umpires that love tennis and love to have an opportunity to be out on the court and be close to the players and be part of a great event.
"But I think when you draw a line that generally I actually am in favour of technology. I think it's proven to be very accurate in this particular instance. I don't see a reason why we need the line umpires, to be honest, if we have technology like this. I would of course keep the ball kids, but line calls I'm in favour of this technology."
Djokovic was speaking after beginning his quest for a ninth Australian Open title with a 6-3 6-1 6-2 win over Jeremy Chardy on Monday.
The 17-time grand slam champion is trying to close the gap on 20-time major winners Roger Federer - who is absent from this year's event - and Rafael Nadal.
"I respect all of my opponents' records. I think especially Roger and Rafa, what they have achieved over the years. They are legends of our sport, and I admire them a lot," Djokovic said. "They have positively affected my game and my growth, my development and all my success. Wouldn't be what it is if these two guys were not there.
"I have had tremendous rivalries with these two guys and we still keep on going. But I don't want any of their success, if you know what I mean. I'm not jealous of their success or anything like that. I try to build my own authentic career and my own success, and I stick to that."
Djokovic added: "I am always motivated and inspired to achieve big goals and break records. I would lie if I say that's not, you know, something that I'm thinking about or that my attention is not going that way.
"I have been very transparent about the fact that one of the biggest goals is to try to reach the number one of all time weeks' record, and I'm getting closer and closer to that one. That's a kind of a lifetime achievement for me.
"Grand slams, as well. Of course the Masters events, I think the 1000 events over the years I have managed to be very consistent and win a lot of titles there. Those are the biggest events that we have on the four other than grand slams. The head-to-head records with top guys as well, to name a few. I try to be a good student of the game.
"I'm just very fortunate to be in this situation and position that I'm in at the moment, so I try to keep on going and obviously setting up new goals for myself, because I feel like other than passion and love that I have for the game and the biggest reason why I still play it is exactly that pure emotion that I have of enjoyment when I'm there and excitement.
"As a professional tennis player, I need to have goals. Over the last 15 years, everything that I have managed to achieve, I don't settle for anything less but the top of the men's game and the biggest trophies. That's something I always aim for. I work towards that. And yeah, I'm still lucky to be where I am. Let's see what the future holds."
Anthony Davis will miss the Los Angeles Lakers' clash with the Oklahoma City Thunder on Monday due to an Achilles injury.
NBA champions the Lakers listed star Davis as out with tendonosis of his right Achilles tendon.
Davis, coming off a championship-winning season with the Lakers, posted 30 points, five rebounds, three assists and two blocks in the team's 135-129 double-overtime victory against the Detroit Pistons on Saturday.
The 27-year-old is averaging 22.3 points, 8.6 rebounds and 3.2 assists per game for the Lakers this season.
The Lakers (18-6) - in the midst of a four-game winning streak - are second in the Western Conference, behind the in-form Utah Jazz (19-5).
Derrick Rose has been traded to the New York Knicks by the Detroit Pistons in exchange for Dennis Smith Jr, it has been confirmed.
The Pistons also received a 2021 second-round draft pick via the Charlotte Hornets.
In New York, former MVP Rose reunites with Tom Thibodeau, who coached him at the Chicago Bulls and Minnesota Timberwolves.
It is Rose's second stint with the Knicks after the 2016-17 season, when he struggled in the triangle offense during Phil Jackson's reign as president of the franchise. He was subsequently picked up by the Cleveland Cavaliers in free agency following the fourth knee operation of his career.
Rose, who is in the final year of a contract that pays him $7.7million, averaged 17.2 points and 5.2 assists in 65 games for the Pistons, though his performances this season have not lived up to the promise he showed in 2019-20.
Smith made just three appearances for the Knicks in 2020-21 and reportedly volunteered to play in the G League bubble to get more minutes on the floor.
He will hope to avoid that after joining the Pistons, whose 5-18 record is the worst in the NBA.
Uncapped duo George Taylor and Charlie Shiel have been called up to the Scotland squad for the Six Nations clash against Wales along with D'Arcy Rae.
Gregor Townsend drafted in centre Taylor, scrum-half Shiel and prop Rae for the round-two encounter at Murrayfield on Saturday between two sides on a high following winning starts.
Rae earned his only cap against Ireland in 2019, coming off the bench in a 22-13 loss.
Ewan Ashman, Blair Kinghorn, Jamie Dobie and Rufus McLean have been released back to their clubs.
Scotland dominated defending champions England on the opening day of the tournament, ending a 38-year wait for a win at Twickenham with an 11-6 victory on Saturday.
Captain Stuart Hogg said they will remain grounded after regaining the Calcutta Cup.
The full-back, who was named man of the match in the defeat of Eddie Jones' side, said: "We are not going to get ahead of ourselves. We will enjoy this one, no doubt, but then it is on to Wales next week.
"We'll get back on the horse and ready to go because next week is another challenge for us and one we're really excited about."
Naomi Osaka said she was "really nervous" before facing Anastasia Pavlyuchenkova but showed no signs of that as she breezed into the second round of the Australian Open.
Osaka looked dominant on day one of the first grand slam of the year as she welcomed being able to play in front of a crowd at Melbourne Park, taking only 68 minutes to wrap up a 6-1 6-2 victory.
The US Open champion has beaten Pavlyuchenkova three times in a row after losing when they first met in 2017 but was wary of facing the Russian on Rod Laver Arena.
Third seed Osaka said: "I was really nervous coming into this match. I know that I've played her before, and it was really tough. I just wanted to play well.
"The most recent memory I have of playing her was in the Osaka final [that Osaka won 6-2 6-3 in 2019], so it's always really hard to play someone that good in the first round.
"For me, I feel like it might have also helped in a way because I calmed my nerves because I felt like I couldn't afford to be that nervous. But, yeah, it was a tough match."
Serena Williams and Simona Halep stormed into round two, but the 2016 champion Angelique Kerber crashed out with a 6-0 6-4 defeat to world number 63 Bernarda Pera.
Alison Riske and Wang Qiang were the only other seeds to fall, losing to teenager Anastasia Potapova and qualifier Sara Errani respectively, while Bianca Andreescu made a winning comeback.
Williams sisters among major winners to make serene progress
Serena Williams did not look at all troubled by a shoulder problem as she started her latest quest to win a record-equalling 24th major singles title with a 6-1 6-1 demolition of Laura Siegemund.
Her older sister, Venus, also advanced in straight sets, beating Kirsten Flipkens 7-5 6-2.
Iga Swiatek, the French Open champion, was too good for Arantxa Rus, winning 6-1 6-3, and Petra Kvitova got past Greet Minnen 6-3 6-4.
Kerber will not be claiming a fourth major crown this month after falling to Croatia-born American Pera.
Halep planning to oust another Australian
Two-time major winner Halep was a cut above Lizette Cabrera, winning 6-2 6-1 in 59 minutes, and is looking forward to facing another Australia in the second round in the form of Ajla Tomljanovic.
"I like to be here, so I like to play Australians," Halep quipped.
"I feel good. My body is fit. It's always difficult to play a big hitter. So, I have to be strong on my legs, focus on myself and give my best.
"I expected a tough match because I played against her before and I know how it's gonna be. She's a good opponent, a good player, and I will focus just on myself like I do every time, but I'm ready for a good battle."
Andreescu back in business
Andreescu put her injury woes behind her, battling past Mihaela Buzarnescu 6-2 4-6 6-3 in her first match for 15 months.
The Canadian had not played in a grand slam since winning the US Open in 2019 but was back in business on John Cain Arena.
Eighth seed Andreescu said: "After the match, I sat down with my team a little bit, and I'm like, 'Oh, guys, here we go again, those three-setters' and they just started laughing because they obviously knew what they were getting themselves into.
"But those matches are super good for me in my opinion because it really shows that I can scramble when I really need to, or if there's some pressure I can dig my way through it somehow. When my back is against the wall, not only today, but I've noticed throughout my last couple tournaments in 2019, I've been able to pull through with those."
Serena Williams will win a 24th grand slam singles title despite the mental pressure of trying to match the record having held her back, Ana Ivanovic says.
American Williams breezed into the second round of the Australian Open on Monday with a 6-1 6-1 victory over Laura Siegemund.
She won her 23rd major singles title in Melbourne in 2017, taking her to within one of matching the all-time record held by Margaret Court.
However, she has failed to win any of the following 14 slams, marking the longest span in her professional career without lifting any of the four biggest trophies.
Williams has won 22 of her majors over the last two decades, at least 15 more than any other women's player in that time, but her most recent four slam finals have ended in defeat.
Ivanovic, the former world number one who reached the final in Melbourne in 2008, wonders if the significance of matching Court's tally may have added extra pressure on Williams.
However, she remains convinced the 39-year-old will claim another title, telling Stats Perform News: "Yeah, definitely after winning so many grand slams, you still have it and especially [as] she reached so many finals, even though she didn't win a title.
"So, I think it's just a matter of, she proved that she can win matches and she can get a part in the grand slams.
"I think she wants to go further for the record. So I think that's maybe a bigger issue than just winning a title. So, it's both a little bit, I guess mental as well. But I'm sure she can do that. And I'm sure that's why she's there and still pushing and still being on top of the game after so many years."
"She's definitely an icon and a very, very powerful player. And I remember you know, when I played against her, she's very intimidating because her serve is just very, very strong. Her shots are very strong. So you feel like you have to attack and move forward otherwise you don't really have a chance. It was very inspiring to play against her and to play against someone who reached so much in women's sport. I think she will go [down] in history. Definitely."
Reigning champion Sofia Kenin begins her Australian Open defence against home hope Maddison Inglis on Tuesday.
The 22-year-old is hoping to become the first women's player to win successive Australian Opens since Victoria Azarenka back in 2013.
Kenin was a finalist at the French Open last year after winning in Melbourne, having failed even to reach the last eight in her first 11 majors, but she was beaten in straight sets by Garbine Muguruza in the quarter-finals of the Yarra Valley Classic warm-up tournament.
"She seemed very, very solid and very consistent lately, so of course she has a big chance but, like I said, it's so difficult to talk because you don't see the players playing, you don't see what kind of form they're on and how the last months have been for them," said Ivanovic.
"And you know, without competition for so long again, it definitely is going to [have an] affect but she can indeed [win]. One Australian Open and then she went on to the French Open final, so she's definitely been very, very consistent and she's going to I think try to go again.
"I think that's why it's very hard to predict who will be the winner of a grand slam, especially on the women's side. But on the other hand, it's nice to see new faces and new players coming up, and it also brings new excitement to the tour."
Ivanovic also tipped French Open champion Iga Swiatek to challenge in the latter stages, adding: "I do like Iga Swiatek and the way she plays. I like her aggressive game. I like the fact that she runs around and hits her forehead, it was kind of the style that I had. So I really hope she can keep up the work that she did last year and continue to do well."
Lewis Hamilton has signed a new contract to race for Mercedes in the 2021 Formula One season, it has been confirmed.
The reigning F1 champion will spend a ninth season with the Silver Arrows after winning a record-equalling seventh drivers' title in 2020.
Mercedes and Hamilton have agreed a deal that includes the formation of a joint charitable foundation with the aim of supporting greater diversity and inclusion in Motorsport.
Hamilton said: "I am excited to be heading into my ninth season with my Mercedes team-mates. Our team has achieved incredible things together and we look forward to building on our success even further, while continuously looking to improve, both on and off the track.
"I'm equally determined to continue the journey we started to make motorsport more diverse for future generations and I am grateful that Mercedes has been extremely supportive of my call to address this issue.
"I'm proud to say we are taking that effort further this year by launching a foundation dedicated to diversity and inclusion in the sport. I am inspired by all that we can build together and can't wait to get back on the track in March."
Team principal Toto Wolff added: "We have always been aligned with Lewis that we would continue, but the very unusual year we had in 2020 meant it took some time to finish the process.
"Together, we have decided to extend the sporting relationship for another season and to begin a longer-term project to take the next step in our shared commitment to greater diversity within our sport.
"Lewis' competitive record stands alongside the best the sports world has ever seen, and he is a valued ambassador for our brand and our partners.
"The story of Mercedes and Lewis has written itself into the history books of our sport over the past eight seasons, and we are hungry to compete and to add more chapters to it."
In a 2020 season that was truncated due to the coronavirus pandemic, Hamilton still made history by breaking Michael Schumacher's all-time F1 wins record with his 92nd victory at the Portugal Grand Prix.
This year he will hope to surpass Schumacher and become the first F1 driver in history to win eight world titles.
The 2021 season is scheduled to get under way with the Bahrain Grand Prix on March 28.
Novak Djokovic began his quest for a ninth Australian Open title with a convincing straight-sets win over Jeremy Chardy.
The reigning champion and world number one looked in ruthless form as he won 6-3 6-1 6-2 in a little over an hour and a half.
Djokovic, who beat Dominic Thiem in a five-set thriller in the 2020 final, was in an authoritative mood as he took the first two sets in just 56 minutes.
Chardy, whose best grand slam result was reaching the quarter-finals in Melbourne in 2013, offered some valiant resistance in game five of the third set before Djokovic eventually claimed the crucial double break.
The 17-time major winner eased through the final two games in front of a jubilant crowd, finishing with back-to-back aces to set up a second-round match with Frances Tiafoe.
"It makes my heart full to see the crowd in a stadium again," said Djokovic, who has reached at least the semi-final stage in seven of his previous nine majors.
"There's an ongoing love affair between me and the Rod Laver Arena. It's definitely one of the most special courts on the tennis tour around the world and my most successful. Every time I step on this court, I relive those memories."
Djokovic's preparations for the tournament were overshadowed by a row over quarantine conditions for players arriving in Australia, the 33-year-old having lobbied Tennis Australia and state authorities to loosen restrictions for 72 players who had to spend two weeks in their hotel rooms.
There was little about his performance on Monday to suggest any distractions from the task at hand, although he bristled a little in the on-court interview when it was put to him he had been "frustrated" in recent weeks.
"I'm just really glad we're free, playing tennis, back in Australia," he then said. "It's a happy place for us, a happy slam."
Data Slam: Djokovic at his clinical best
Djokovic dropped just nine points on serve and hit 41 winners to just 11 unforced errors, sending down nine aces and one double fault.
Such imperious play left Chardy, who had lost all 13 of their previous encounters, with little chance of an upset.
WINNERS/UNFORCED ERRORS
Djokovic – 41/11
Chardy – 20/26
ACES/DOUBLE FAULTS
Djokovic – 9/1
Chardy – 3/3

Lewis Hamilton has signed a new contract to race for Mercedes in the 2021 Formula One season, it has been confirmed.
Serena Williams took inspiration from the "unbelievable" Tom Brady as she cruised into the second round of the Australian Open with a "vintage" performance.
Brady made yet more history on Sunday, the most successful player in NFL history winning a seventh Super Bowl as the Tampa Bay Buccaneers beat the Kansas City Chiefs 31-9.
The incredible Brady, 43, showed age is no barrier, throwing three touchdown passes – two of which were scored by his long-time friend Rob Gronkowski – and completing 21 of 29 throws for 201 yards.
Brady did now allow any interceptions as he picked up the MVP award at Raymond James Stadium.
Williams started her quest for a record-equalling 24th grand slam singles title with a 6-1 6-1 defeat of Laura Siegemund on Monday, then paid tribute to her fellow American Brady.
She said of his exploits: "It's unbelievable. I just was watching as much as I could to see. My only word is it's unbelievable. I kept saying: 'This is unbelievable, this is unreal'.
"You can't say it was the system he was at formerly [the New England Patriots]. It's definitely Tom Brady, he's Tom Brady. He's amazing."
Brady banished everyone from his house in the days leading up to the Super Bowl so he could fully focus on inspiring the Buccaneers to victory, but the 39-year-old Williams said she could never do the same as she would not want to be separated from her daughter, Olympia.
"I would not be able to go function without my three-year-old around," Williams said. "I think I would be in a depression.
"We've been together every day of her life, so... Is that healthy? Not at all! Not even close. But every single day I just want to be around her. It's great. Everyone's different.
"I can totally understand why he would banish because if I had the strength to do it, I would too.
"I could see it's definitely a distraction, especially every year that I've played except for the past few months, I finally am starting to get better at it. The first two and a half years was very difficult. I wasn't strong enough to do the banishment."
Williams, who will face Nina Stojanovic in the second round at Melbourne Park, was delighted with the manner in which she swept Siegemund aside and had no issues with her shoulder after withdrawing from a pre-tournament event citing an injury problem.
"This was a good start. Definitely vintage 'Rena'. It's definitely good. I think I'm pretty good at pacing myself in a grand slam," she said.
"I was happy just to get through it. Wasn't sure how my serve would be after a little bit of that shoulder, but it's feeling good, I'm feeling good. So, it felt really good.
"Last year was very crazy for the world, and to be able to do what I love and to be able to come out and compete and play at a grand slam, after the last 12 months, it makes me appreciate the moment even more."
Tom Brady claimed a seventh Super Bowl crown after leading the Tampa Bay Buccaneers to their first Lombardi Trophy since the 2002 season with a dominant victory over defending champions the Kansas City Chiefs.
Serena Williams' bid for a record-equalling 24th grand slam title started with a comprehensive win over Laura Siegemund at the Australian Open.
The American star was dominant on her way to a 6-1 6-1 victory over Siegemund on Rod Laver Arena on Monday.
Williams is aiming to join Margaret Court on a record 24 grand slam singles titles and she had no problems against the German in Melbourne.
She improved to 20-0 in the first round of the Australian Open, showing few signs of a shoulder injury she expects to be dealing with throughout the tournament.
Williams lost just 10 games in her previous two wins over Siegemund, but the seven-time Australian Open winner was broken in the opening game.
But Siegemund produced too many errors from then on, Williams winning in just 56 minutes to set up a clash against Nina Stojanovic.
Data Slam: Serena cruises after initial nerves
Williams was broken to 15 in the opening game when Siegemund produced a forehand return winner. However, she steadied, reeling off the next 10 games on her way to a comfortable win.
WINNERS/UNFORCED ERRORS
Williams – 16/15
Siegemund – 4/20

The NBA-leading Utah Jazz won for the 15th time in 16 games after defeating the Indiana Pacers 103-95.
Jazz star Donovan Mitchell fell just one rebound shy of a triple-double – finishing with 27 points, 11 assists and nine boards to inspire Sunday's victory.
The Jazz improved their NBA-best record to 19-5 as the slate of five league games took place before the NFL's Super Bowl LV, despite the absence of injured star Mike Conley.
Rudy Gobert contributed 16 points and 16 rebounds for the in-form Jazz, while Domantas Sabonis led the slumping Pacers with 20 points.
Elsewhere, the Los Angeles Clippers were upstaged by the Sacramento Kings 113-110.
The Clippers had won both games against the Kings this season by a combined 56 points. Since the start of 2010-11, the Clippers were 33-7 against the Kings – the best record by any team against a divisional opponent in that span, per Stats Perform.
But Kawhi Leonard and the Clippers were stunned in Los Angeles, where De'Aaron Fox's 36 points, seven assists and four rebounds fuelled the Kings to a fourth successive victory.
Kings team-mate Buddy Hield added 22 points and nine rebounds, while Richaun Holmes put up 12 points and 10 rebounds.
Leonard's double-double of 20 points and 10 rebounds was not enough for the Clippers, who suffered back-to-back defeats for the first time this season.
Beal stars again but Wizards fall
It was a familiar story for Bradley Beal. The star guard led the way with 31 points however the struggling Washington Wizards went down 119-97 to the Charlotte Hornets. Terry Rozier (26) and Gordon Hayward (25) combined to score 51 points for the Hornets.
The Miami Heat topped the New York Knicks 109-103 thanks to Bam Adebayo (24 points and 11 rebounds) and Jimmy Butler (17 points, 10 rebounds and nine assists).
Inefficient Walker
The 2020-21 season has not gone according to plan for Kemba Walker. He was just four-of-20 shooting from the field, while making only four of 11 three-point attempts for 14 points in the Boston Celtics' 100-91 loss to the Phoenix Suns.
Knicks star Elfrid Payton had seven points on three-of-12 shooting against the Heat. He also missed both of his efforts from beyond the arc.
Butler and Bam combine
There has been a hangover in Miami following the Heat's memorable run to last season's NBA Finals. But Butler and Adebayo provided a reminder of what they are capable of with a powerful dunk – the former the architect against the Knicks.
Sunday's results
Utah Jazz 103-95 Indiana Pacers

Thunder at Lakers
The Oklahoma City Thunder (10-12) will make the trip to defending champions the Los Angeles Lakers (18-6) on Monday. LeBron James and the Lakers have won four games in a row.
Wales are set to be without four players for their Six Nations clash with Scotland next Saturday as they count the cost of a hard-fought win over Ireland.
Wayne Pivac's men had to recover from a first-half blip as they surrendered a 6-0 lead to 14-man Ireland after the visitors had Peter O'Mahony sent off for leading with the elbow to the head of Tomas Francis.
Ireland went into the break 13-6 ahead despite their personnel disadvantage, but tries from George North and Louis Rees-Zammit proved enough for Wales to claim a 21-16 victory.
However, it was something of a pyrrhic triumph with Johnny Wiliams and Hallam Amos poised to miss the visit to Murrayfield with head injuries, while Pivac also ruled out Tomos Williams with a hamstring issue and Dan Lydiate, who is suspected to have a knee ligament problem.
"We've picked up a few injuries so we're looking at those now, we'll make a better assessment [on Monday]," Pivac said.
"We're sort of counting the walking wounded after that one.
"The six-day turnaround means certain players won't be playing for us, two with the head knocks. A six-day turnaround means any head knocks, you're gone.
"Unfortunately we lose a couple of players straight away. We'll see how the rest of the squad is [on Monday] and look at what sort of side we can put together on Tuesday.
"Johnny Williams went off for a HIA [head injury assessment] and didn't come back on. The other one was Hallam Amos who took a late knock too. Those are the two head knocks.
"Then we've got a hamstring for Tomos Williams – we're hoping that's not serious but it won't turn round in six days, I wouldn't have thought."
Pivac added of Lydiate: "We're going to get that scanned but it's not looking too good. It could be an ACL but we'll get that scanned for a definite result.
"It's very disappointing for Dan and he's very disappointed in the changing room right now."
Ireland coach Andy Farrell, meanwhile, expressed confidence O'Mahony will make amends for his indiscretion, telling BBC Sport: "We've seen red cards for that in the past haven't we?
"I think we've seen yellow cards for other incidents that didn't quite go our way.
"He's been around enough a long time and he's gutted. He's been a pretty stalwart player for us in the past and he'll continue to do so in the future."
Wales took advantage of Peter O'Mahony's early dismissal and survived a fightback from 14-man Ireland to start their Six Nations campaign with a 21-16 win in Cardiff.
O'Mahony was sent off in the opening 15 minutes for contact to the head but Andy Farrell's men overcame their disadvantage in personnel to lead 13-6 at the interval.
But tries from George North and Louis Rees-Zammit turned the contest back in Wales' favour, with Ireland unable to produce another riposte.
The visitors were also dealt a late blow as Johnny Sexton went off with a head injury, giving Farrell plenty to worry about ahead of next week's clash with France.
Ireland were pinned for side entry at the ruck in the opening five minutes, giving Leigh Halfpenny the chance to boot Wales into a three-point lead.
O'Mahony was guilty of a much more serious infraction in the 14th minute, the flanker seeing red for leading with the elbow to the head of Tomas Francis as he attempted a clearout.
Wales, who earlier lost Dan Lydiate to a leg injury, doubled their advantage four minutes later through Halfpenny's trusty right peg.
However, Ireland enjoyed the majority of possession and territory thereafter in the first half and were rewarded for an extremely spirited fightback.
A pair of Sexton penalties drew Ireland level and a break from Robbie Henshaw then enabled Tadhg Beirne to dive over and give them a seven-point lead to defend.
Wales saw scrum-half Tomos Williams suffer a hamstring injury on the stroke of half-time but his absence did not prevent the hosts from getting back into the contest.
North capitalised after a series of Ireland handling errors to surge through a gap on the right and touch down, but Halfpenny misjudged the conversion attempt.
But that instance of profligacy from the tee did not prove costly as Rees-Zammit produced a stunning finish in the right-hand corner to put Wales back in front.
Halfpenny atoned for his earlier miss with a superb kick from the sideline to add the extras before knocking over a more routine kick as a penalty made it 21-13.
Billy Burns trimmed the deficit back to five points shortly after Sexton's exit but he failed to find touch with a penalty as he attempted to push Ireland to the five-metre line in stoppage time as Wales survived a dramatic final push from the visitors.
"This season is about making sure history remembers us as we wish to be remembered. This season is about adding to our legacy. And I can't wait, Dodger fans."
While the Los Angeles Dodgers are yet to announce the deal, Trevor Bauer revealed his free-agency decision via his YouTube channel on Friday.
Hot off being crowned the National League (NL) Cy Young award winner with the Cincinnati Reds in 2020, Bauer is getting paid after the opting to join World Series champions the Dodgers instead of the New York Mets in a record-breaking deal.
Bauer - the first Cy Young winner to enter free agency since Greg Maddux in 1992 - is reportedly due to earn $40million in 2021 and $45m in 2022. The 2021 salary would make him the highest-paid player in MLB history, a record he would break again the following year.
The right-handed ace will help form an intimidating Dodgers bullpen, which also includes past Cy Young winners Clayton Kershaw and David Price, plus star pitcher Walker Buehler.
As Bauer looks to experience success in Los Angeles, where Mookie Betts, Cody Bellinger and Corey Seager spearheaded the Dodgers to World Series glory for the first time since 1988, we take a look at the numbers behind the 30-year-old using Stats Perform Data.
Bauer joins Cy Young club but is success on the horizon?
Bauer led the NL in ERA (1.73), WHIP (0.795), opponents' batting average (.159), opponents' BABIP (.215), adjusted ERA-plus (276), hits per nine innings (5.1), shutouts (two) and complete games (two) in the coronavirus-shortened 2020 campaign.
He also ranked second in strikeouts (100) and strikeouts per nine innings (12.3).
In nine seasons since he broke into the majors with the Arizona Diamondbacks in 2012, Bauer is 75-64 with 1,279 strikeouts and a 3.90 ERA. His only All-Star selection came in 2018.
Bauer is the eighth reigning Cy Young award winner to change teams that subsequent offseason after taking his talents to LA, and the fourth to do so in free agency, following Catfish Hunter (1975), Mark Davis (1990), Maddux (1993), David Cone (1995), Pedro Martinez (1998), Roger Clemens (1999) and R.A. Dickey (2013).
Did those players go on to enjoy further success?
Hunter made two All-Star teams with the New York Yankees in 1975 and 1976, Maddux won the NL Cy Young in that 1993 season with the Atlanta Braves as well as in 1994 and 1995 while he also earned All-Star selection between 1994-98 and in 2000, to go with Gold Glove honours in his first 10 years in Atlanta, where World Series victory followed.
Cone was an All-Star with the Yankees in 1997 and 1999, Martinez earned Cy Young Awards with the Boston Red Sox in 1999 and 2000, made All-Star teams in 1998, 1999, 2000 and 2002 (and in 2005 and 2006 with the Mets).
Clemens was a Cy Young winner with the Yankees in 2001 and the Houston Astros in 2004. He also made All-Star teams in 2001 and 2003-05 (the latter with the Astros), while Dickey's first year in Toronto saw him secure Gold Glove status.
Ace trio to lead back-to-back bid?
The star-studded Dodgers now boast three Cy Young winners in superstar Kershaw, veteran Price and Bauer.
The last team with three? The 2014 Detroit Tigers, who had a certain Price, Justin Verlander and Max Scherzer in their rotation.
That 2014 Tigers side went 90-72 and won the American League (AL) Central, but were swept by the Baltimore Orioles in the American League Division Series (ALDS) 3-0.
The Cy Young trio started those three playoff games, combining to go 0-2 with a 4.43 ERA. Detroit did not acquire Price that year until the trade deadline; from August 1 to the end of the regular season, the Tigers were 32-25 with a 3.94 team ERA (3.97 from starters).
The Dodgers are the first World Series champions to add a reigning Cy Young award winner that offseason, after the 1999 Yankees, who prised Clemens to New York and went on to win the ultimate prize that year.
But how does Bauer compare to three-time Cy winner Kershaw (32) and 2012 recipient Price (35)?
Bauer's career numbers do not really measure up to the other two, especially Kershaw, with the exception of his strikeout rate - the younger Bauer comes in at 9.7, level with Kershaw and ahead of Price (8.8).
But just looking at the last three seasons, Bauer has more than held his own.
Since 2018, Bauer has a .211 BA allowed percentage - fewer than Kershaw (.220) and Price (.241).
When it comes to strikeouts per nine innings, Bauer comes in at 11.2, ahead of Price (9.7) and Kershaw (9.2), while the Dodgers recruit (1.0) has fared much better than Price (1.3) and Kershaw (1.2) when it comes to home runs per nine innings.
Bauer also has postseason and World Series experience, having made 10 playoff appearances with the Cleveland Indians and one with the Reds.
In the NL Wild Card Series against the Braves last season, Bauer allowed just two hits and struck out 12 over 7.3 innings.
Steve Kerr feels Stephen Curry is playing the best basketball of his career after his impressive 57-point outing in the Golden State Warriors' defeat to the Dallas Mavericks.
Curry joined Wilt Chamberlain as the only Warriors players to post multiple 55-point games in a campaign with a season-high 11 three-pointers in Saturday's thrilling clash.
It was not enough for the Warriors as Luka Doncic tied his career high of 42 points to inspire his side to a 134-132 victory, snapping a six-game home losing streak.
However, Kerr was blown away by Curry's shot-making ability, with the two-time MVP's 57 points - the second-best total of his career - coming on 19-of-31 shooting from the field.
"He's never played better," Kerr said. "We're talking about a two-time MVP, three-time champion. I've never seen him like this. He just looks so strong to me.
"He's obviously always been an incredible shooter, but he looks stronger to me just getting by people, fending them off on drives to the rim, finish, and of course the shot-making.
"It's almost unfathomable what he's doing out there."
Doncic, who is yet to outscore Curry in a head-to-head contest, was also amazed by the Warriors superstar's performance at the American Airlines Center.
"Every time he shot the ball, I thought it was going in," Doncic told ESPN. "It was something unbelievable. He's an amazing player.
"He changed the game and it's always fun to play against him, and today we got a win, but it's always fun to play against him."
Elsewhere in Saturday's NBA action, champions Los Angeles Lakers beat the Detroit Pistons 135-129 in double overtime.
LeBron James had 33 points, eight of those points coming in the second overtime as the Lakers survived a scare against a Pistons side with just five wins all term.
James, who also had 11 assists to make it 10 double-doubles for the season, joked he is getting too old to be taken the distance.
"I was just ready to go," he said. "I'm 36 years old... my heart is not sustainable for two overtimes at this point in my career!
"I've got a bottle of wine at home ready to be opened, and I delayed it for two overtime periods."
Rafael Nadal is "doing everything possible" to play a part in the Australian Open after suffering from back pain for the past two weeks.
The 34-year-old pulled out of Spain's line-up for the ATP Cup earlier this week and was last in competitive action in November's ATP Finals.
Nadal is due to face Laslo Djere in the first round on Tuesday as he seeks a second Australian Open title, but the Spaniard cannot guarantee he will be able to play the match.
"It's not great, obviously," he said. "It's true that for the last 15 days I have been suffering.
"In the beginning, the muscle was just a little bit tired, but I now feel a little bit more stiff than usual.
"The muscle is still tight, so it is difficult to play with freedom of movement."
But Nadal, who has a history of back injuries, is refusing to withdraw from the tournament.
"I have Monday and then playing Tuesday. I don't think about not playing," he said.
"We are doing everything. My physio is here, the doctors [are] here, everybody is helping me in all possible ways. I hope to be ready, that's all. I know sometimes things change quick."
Nadal is not alone in entering the first grand slam of the year below full strength, with the likes of Serena Williams, Sofia Kenin and Naomi Osaka also battling injury problems.
However, the world number two will not use his niggling back issue as an excuse should he suffer an early exit at Melbourne Park.
"I'm not a big fan of finding excuses," he said. "When things happen, you need to find a way to get through."
Nadal can surpass Roger Federer for all-time majors should he triumph at the Australian Open.
He is also looking to become only the second man after Rod Laver to win each major on more than one occasion in the Open era, but his only previous success at the tournament came 12 years ago.
"I think I had the big chance in 2014. I got injured during the match on the back. It was tough," he said.
"I had another good chance in 2012, another good chance in 2017 with a break up in the fifth. I just didn't win the match.
"That's all, I can't find another reason. It is true that I missed a couple of Australian Opens for injuries, too."
