Top seed Cristian Garin will fly the flag for Chile in the quarter-finals of the Chile Open after beating compatriot Alejandro Tabilo in the second round.

The only two remaining home hopes in Santiago went head-to-head on Thursday and it was world number 22 Garin who came out on top 6-2 6-2.

Garin, a four-time ATP Tour winner, was forced to retire from the tournament in the last eight last year but will look to reach the semi-finals for the first time when he takes on Peruvian qualifier Juan Pablo Varillas.

The 24-year-old Garin is one of only three seeds remaining in the competition after Varillas' upset win over Federico Coria in straight sets and Daniel Elahi Galan's defeat of Pablo Andujar.

Garin cannot now play another seeded player until the final.

There were 124 years of All-Star experience at last weekend's showcase game between Team LeBron and Team Durant in Atlanta. 

The Chicago Bulls' Zach LaVine was responsible for one of those years. 

And of all the exceptional players at last weekend's event, the first-time All-Star from the Bulls is one of the more intriguing. 

While several All-Stars are future Hall of Famers – the Los Angeles Lakers' LeBron James, Golden State Warriors' Stephen Curry and Phoenix Suns' Chris Paul just to name a few – and others are young and established stars – the Dallas Mavericks' Luka Doncic, Utah Jazz's Donovan Mitchell, Philadelphia 76ers' Ben Simmons – LaVine is a veteran who is suddenly developing into a superstar. 

In fact, over the past five weeks, no one is scoring more than LaVine, who is averaging a league-best 32.3 points since February 6, while making exactly half of his 104 three-point attempts. 

He's been so spectacular he's played himself into max contract talk, although other discussions have had his name in various trade rumours if the rebuilding Bulls do not plan to sign him to an extension before his contract expires in 2022. 

Now in his fourth season in Chicago after spending his first three with the Minnesota Timberwolves, LaVine has the Bulls in position to participate in the Play-In Tournament and possibly earn their first postseason berth since 2016-17. 

He has the Bulls on the cusp of the playoffs behind a breakout season in which he is averaging career highs in every major category – 28.7 points per game, 5.2 rebounds per game, 5.1 assists per game and 3.5 made three-pointers per game, while shooting 52.5 per cent on all field goals and 43.5 per cent on threes. 

If those numbers look impressive, that is because they have only been reached once before in a single season in NBA history. 

LaVine joins Stephen Curry from 2015-16 as the only players ever to average 25-plus points, five-plus rebounds, five-plus assists and three-plus made three-pointers per game, while shooting 50 per cent on field goals and 40 per cent on threes. Curry won his second MVP that season while leading the Warriors to a record 73 wins. 

While Curry was already an established star at that point after winning league MVP honours and an NBA title the season prior, LaVine is unexpectedly proving that he also belongs among the upper echelon of players in the league. 

He has transformed himself into one of the league's most dangerous scorers, capable of knocking down a three-pointer, pulling up and hitting a mid-range jumper or beating his man off the dribble and finishing at the rim. 

Coming out of the All-Star break, his 167 dunks and layups are seventh-most in the NBA – and the most by any guard. And while the six-foot-six LaVine was also among the league leaders in dunks and layups last season (11th with 287), he is finishing at higher rate. 

He is converting 64.2 per cent of his dunk and layup attempts this season after making 57.4 per cent of his attempts last season, and that increase in field goal percentage of 6.8 is the eighth largest by any player six-foot-six or shorter. 

While many of the leaders among dunks and layups are big men – New Orleans Pelicans power forward Zion Williamson, Milwaukee Bucks power forward Giannis Antetokounmpo and Jazz centre Rudy Gobert – who live in the paint, the dynamic LaVine is just as much of a threat to knock down a three-pointer. 

His 120 made three-pointers rank fifth in the league and he is the league's only player with more than 120 dunks and layups and 90 threes. 

It is one thing to have made a lot of threes but another to actually be an efficient shooter – the Sacramento Kings' Buddy Hield has made 20 more three-pointers than LaVine but has hoisted up 94 more attempts – and LaVine has refined his shooting touch and is deadly from beyond the arc. 

He is hitting 43.8 per cent of his three-point attempts from the wing and his 53.8 per cent shooting from the corner ranks sixth in the league among the 103 players with at least 30 attempts.   

Overall, LaVine is shooting 43.5 per cent on three-pointers, an increase of 0.55 per cent from the perimeter from last season – the eighth-largest improvement in the NBA among players with at least 150 three-point attempts this season and last. 

The mid-range shot is somewhat of a lost art in the current game with the added weight given to a shot from a few feet further back beyond the arc, but it still has a place and if a shooter can connect from mid-range with regularity he becomes all the more threatening to score. 

LaVine has found his touch from mid-range, making 44.6 per cent of those shots this season after hitting at a 31.9 per cent clip last season. That increase of 12.7 per cent is the sixth-largest in the NBA among 73 shooters who have attempted at least 50 mid-range shots this season and last. 

Shooters shoot, and LaVine is thriving. His effective field goal percentage of 61.5 ranks second in the NBA among all guards. 

His all-round offensive game is one of the most complete in the league, and opposing defences are tasked with game planning against him, giving him similar treatment as they would give Curry or James, as he is a threat to score from anywhere on the court. 

Curry and James, however, have won multiple MVPs and titles. LaVine is certainly putting up MVP-type numbers, but the Bulls are not in the championship conversation. 

At the moment, at least. 

Chicago are only two games back of the Boston Celtics for the fourth seed in the Eastern Conference and are viewed as a team on the rise under first-year Bulls coach Billy Donovan. Instead of trading LaVine as was being speculated weeks ago, it is possible Chicago will be buyers at the March 25 trade deadline in their pursuit of a playoff berth. 

And if LaVine continues to excel and Chicago continue to improve over the next few seasons, MVP awards and NBA titles might not be out of the question for LaVine and the Bulls. 

Elise Mertens came from behind to clinch a semi-final spot at the Dubai Tennis Championships but Coco Gauff bowed out on Thursday.

Mertens said she "just didn't want to let go" after coming back from the brink to end Jessica Pegula's fine run with a 5-7 7-5 6-0 victory.

The Belgian looked to be heading out when she faced a 5-2 deficit in the second set, yet saved three match points to force a decider.

"I kept on fighting and that was the spirit today," said world number 18 Mertens.

Former world number one Muguruza is Mertens' semi-final opponent, the Spaniard having come from a set down to beat third seed Aryna Sabalenka 3-6 6-3 6-2.

Muguruza lost out to Petra Kvitova in the final of the Qatar Open last week, but looks on top form as she closes in on another championship match.

Sabalenka fell foul of Muguruza in Doha, and the Belarusian was unable to gain revenge as the ninth seed earned a 16th win of the season.

There was to be no place in the last four for 16-year-old Gauff, who came up short against world number 54 Jil Teichmann.

Gauff, who defeated Teichmann twice in Australia in February, was broken to go 5-3 down in the first set and could not respond.

A second break in Teichmann's favour put Gauff on the back foot in the second, and the Swiss then saved three break points to nose into a 3-1 lead.

The contest was settled on Gauff's serve – Teichmann taking the match at the second time of asking to tee up a last-four clash with Barbora Krejcikova, who beat Anastasia Potapova 6-0 6-2 in a little over an hour.

Krejcikova was beaten in the doubles final last year, and has claimed her place in the singles semi-finals of a WTA 1000 event for the first time.

Roger Federer's return to the ATP Tour lasted just two matches at the Qatar Open as he was beaten in the last eight by the brilliant Nikoloz Basilashvili.

Virat Kohli has ruled out Ravichandran Ashwin making a Twenty20 return for India anytime soon ahead of the five-match series against England.

Ashwin was named man of the series in a 3-1 Test series victory over England that sealed India's place in the ICC World Test Championship final against New Zealand.

The off-spinning all-rounder took 32 wickets and averaged 31.50 with the bat, scoring a magnificent century on his home ground in Chennai.

Ashwin has not played for his country in the shortest format since July 2017 and it appears that is not about to change with a Twenty20 World Cup to come on home soil this year, as India have full faith in Washington Sundar.

India captain Kohli said ahead of the first T20 on Friday: "Washington has been doing really well for us, so you can't have two players of the same discipline playing in one squad.

"Unless Washi has a drastically horrible season and things go south for him. The question has to be asked with some kind of logic as well.

"You suggest where you would add Ash and play him in the team when someone like Washington already does that job for the team. So, it's easy to ask the question but you should have a logical explanation to it yourself."

Kohli vowed his side would take a positive approach from the start when they face a top-ranked England team, with all matches in the series being played at Narendra Modi Stadium in Ahmedabad.

The skipper said: "The kind of players we have added into the squad is precisely to give our batting line-up more depth and not play in a similar kind of pattern that we have played with in the past.

"We want to be a side that plays free cricket, not have any baggage of lack of depth and one guy having to bat long enough to make sure we get to a big total.

"We have explosive batsmen in the team now, who can change the game at any stage even if you are two or three wickets down. That's exactly what we've tried to address in picking this squad.

"So this time around, you will see guys a bit more expressive in terms of approaching the innings, and playing more freely.

"I'm not worried about whether we have enough batsmen to take care of things if we lose a couple of wickets early, which was the case before to be honest. We didn't have enough depth in the batting to be able to play freely throughout the first 10 or 12 overs. But I see us being much more positive and free from this period onwards."

Juventus defender Merih Demiral has been ruled out for around three weeks with a thigh injury.

The Turkey international sustained the damage late on in Tuesday's 3-2 win over Porto, which saw Juve exit the Champions League on away goals at the last-16 stage.

Juve confirmed on Thursday that Demiral, who has been plagued by a number of injury setbacks over the past year, suffered low-grade tissue damage.

He is expected to miss 20 days, potentially ruling the 23-year-old out of Juventus' Serie A games with Cagliari, Napoli and Benevento.

Demiral is subsequently a major doubt for Turkey's World Cup qualifying triple-header against the Netherlands, Norway and Latvia later this month. 

Juve have an identical win rate with and without Demiral in Serie A this season, winning 60 per cent of their 10 games with the centre-back in their starting lineup and the same amount in the 15 games without.

He leads the way in terms of blocks per 90 minutes among Juve defenders in Serie A this term with 0.88, while only Giorgio Chiellini (3.72) has managed more clearances and headed clearances (2.29) than Demiral's 3.63 and 2.16 respectively.

However, the former Sassuolo man lacks in other areas, his 60.26 attempted passes per game some putting him some way behind Matthijs de Ligt's 76.26. 

In fact, only Gianluca Frabotta (51.16) attempts fewer passes on average than Demiral among Juve defenders to have featured more than once in the league in 2020-21.

Silverstone is "absolutely" open to hosting one of the proposed new Formula One sprint races in 2021.

Plans have been drawn up to introduce shorter races on Saturdays at three circuits, which would precede the traditional grand prix a day later.

F1 president Stefano Domenicali told the Daily Mail that Silverstone was one of the proposed venues for the inaugural races, with teams said to be broadly in support of the new format.

The grands prix in Montreal, Monza and Interlagos are also reportedly under consideration to host sprint races.

Asked by Sky Sports if Silverstone welcomed the proposals, the circuit's managing director Stuart Pringle said: "Absolutely.

"If F1 should decide that Silverstone is the right venue for a sprint race then we would be totally supportive of that and feel it would be a fantastic spectacle for the fans."

The idea was first mooted in a meeting of the Formula One commission in February, after which F1 and governing body FIA issued a statement that said: "All teams recognised the major importance of engaging fans in new and innovative ways to ensure an even more exciting weekend format.

"There was, therefore, broad support from all parties for a new qualifying format at some races, and a working group has been tasked with creating a complete plan."

The proposal is for the sprint races, lasting roughly 30 minutes, to take place on the Saturday of a grand prix weekend. Qualifying would be moved to the Friday in place of the second practice session, with results determining the starting grid for the sprint event.

These shorter races would offer points for drivers and constructors, with the precise numbers yet to be determined, and decide the starting order for the main event on Sunday.

There would be no podium celebration after the sprint race, according to Domenicali, who is keen to preserve "the prestige of the grand prix itself".

Williams team principal Simon Roberts said this week, as per Race Fans: "We're all running carry-over cars [from 2020]. So fundamentally, we're not expecting massive shifts in the pecking order. So, let's try something.

"But there's a lot of detail being discussed in the background. The idea's cool, the concept's easy, but then in the detail, how do you actually [run] the weekend – how do you do tyres, what can you do, what can't you do – that's still in negotiation."

Germany head coach Joachim Low has insisted no final decision has been made on possible recalls for Bayern Munich forward Thomas Muller and Borussia Dortmund defender Mats Hummels.

The experienced pair have not played for their country since being told by Low in March 2019 that they, along with Jerome Boateng, had no future with the national team.

Low's decision to focus on younger talent has not always paid dividends, though, and last November's 6-0 demolition by Spain prompted loud calls from the likes of Mesut Ozil to bring those senior players back into the fold.

A report in Kicker claimed Muller and Hummels are set to be handed places in Low's Euro 2020 squad, which will be his last major tournament in charge before he steps down after 15 years in the role.

While insisting he has made no promises over either player's future, Low did admit the impact of the coronavirus pandemic could mean his planned "upheaval" of the team may have to be put on hold.

"I neither opened nor closed the door," he said when asked about Muller and Hummels' possible return.

"I said that, under normal circumstances, you shouldn't interrupt a radical change. We have the pandemic situation, and perhaps you can consider: should I interrupt the upheaval [of the squad] for a tournament?"

Muller, 31, has played 100 times for Germany since making his debut in 2010 and, like Hummels – who has 70 caps – he was part of the squad that won the World Cup in 2014.

Muller's club form in the past two years, particularly during Bayern's treble triumph in 2019-20, has led to a clamour for his return to the national team.

Since the start of last season, as well as scoring 27 goals in all competitions, he has provided 37 assists, the most of any player in Europe's top-five leagues apart from Kevin De Bruyne (38).

Only two Bundesliga players – Erling Haaland (65) and Robert Lewandowski (109) – have had more direct goal involvements than Muller in that time.

Speaking of a possible Germany comeback, he said: "I feel comfortable in the [Bayern] team. Standing on the pitch with the boys is fun, and there are a lot of national team players on the pitch.

"I feel like chasing titles in the summer. We will see if it is the end for me after the Champions League final or whether I will play for the national team. I'm definitely ready."

Inter midfielder Arturo Vidal is to undergo surgery on his left knee.

The Serie A leaders announced on Thursday that Vidal has been suffering from meniscus pain.

The experienced Chile international will be treated at the Humanitas Institute in Rozzano on Friday.

Vidal, 33, has made 30 appearances in all competitions for Antonio Conte's side this season, scoring two goals and providing one assist.

The former Juventus star has won 1.2 tackles and 5.2 duels on average per 90 minutes this season. Among Inter midfielders, only Nicolo Barella (six) averages more successful duels per game.

The Nerazzurri, who are six points clear at the top of Serie A, face Torino away from home on Sunday.

Max Malins will make his first Test start and Virimi Vakatawa returns to the France side for Saturday's mouthwatering Six Nations showdown at Twickenham.

Malins gets the nod at full-back, with Elliot Daly dropping to the bench in three changes made to the side by Eddie Jones.

Hooker Luke Cowan-Dickie is preferred to Jamie George, while Charlie Ewels takes Jonny Hill's place in the second row in an England side that will not be retaining their title after a defeat to Wales last time out.

Anthony Watson will win his 50th Test cap as the defending champions attempt to strike a blow to France's bid to claim the title with a victory in Le Crunch.

France return to action a month after they made it two wins out of two with a defeat of Ireland in Dublin, with their clash against Scotland postponed due to a coronavirus outbreak in the camp.

Head coach Fabien Galthie, who was among those to test positive for COVID-19, has named fit-again centre Vakatawa in midfield alongside Gael Fickou, with Arthur Vincent unavailable.

Teddy Thomas returns on the wing in place of the injured Gabin Villier, while Romain Taofifenua comes into the team after Bernard Le Roux was ruled out.

Dylan Cretin is preferred to Anthony Jelonch in the back row as the fit-again Romain Ntamack has to settle for a place on the bench when France go in search of a first win at Twickehham since 2007.

England: Max Malins, Anthony Watson, Henry Slade, Owen Farrell, Jonny May, George Ford, Ben Youngs; Mako Vunipola, Luke Cowan-Dickie, Kyle Sinckler, Maro Itoje, Charlie Ewels, Mark Wilson, Tom Curry, Billy Vunipola.

Replacements: Jamie George, Ellis Genge, Will Stuart, Jonny Hill, Ben Earl, Dan Robson, Ollie Lawrence, Elliot Daly

France: Brice Dulin, Teddy Thomas, Virimi Vakatawa, Gael Fickou, Damian Penaud, Matthieu Jalibert, Antoine Dupont; Cyril Baille, Julien Marchand, Mohamed Haouas, Romain Taofifenua, Paul Willemse, Dylan Cretin, Charles Ollivon, Gregory Alldritt.

Replacements: Camille Chat, Jean-Baptiste Gros, Dorian Aldegheri, Cyril Cazeaux, Cameron Woki, Anthony Jelonch, Baptiste Serin, Romain Ntamack.

Rafael Nadal has turned down a wildcard invitation to compete in next week's Dubai Tennis Championships as he does not feel ready to return to action.

The world number two has been struggling with a lower back injury sustained prior to the Australian Open, which he exited in the quarter-finals at the hands of Stefanos Tsitsipas.

Nadal has not competed since, having subsequently pulled out of the ATP Cup and Rotterdam Open after being advised to give his back time to heal.

And the 20-time grand slam winner will delay his return for a little while longer after deciding to skip the upcoming ATP 500 event in Dubai.

"I would like to thank the @DDFTennis for the wild card invitation sent to me," Nadal posted on his Twitter page on Thursday. 

"We seriously thought about coming to play, but I don't think I am ready to play yet. Once again thanks to the tournament's kind invitation and best of luck with the tournament."

The Spaniard added in a later tweet: "And special thanks to Tournament Director Salah Talak since I am aware of his efforts to ensure a smooth arrival to play Dubai during this unprecedented Coronavirus pandemic and difficult times for all."

Nadal won his only Dubai Tennis Championships title in 2006 with victory over Roger Federer – the competition's record eight-time winner – in the final.

Federer is scheduled to take part in this year's tournament after making his long-awaiting return from a 14-month injury lay-off at the Qatar Open this week.
