Nick Kyrgios took a swipe at his critics after storming to a mesmerisingly brilliant second-round win at Wimbledon, setting up an appetising clash with Stefanos Tsitsipas.

The 27-year-old Australian was largely all business and no nonsense as he won 6-2 6-3 6-1 in one hour and 25 minutes against 26th seed Filip Krajinovic, delivering the kind of performance that underlines his potential threat at this tournament.

Yet Kyrgios had been far from his best against British player Paul Jubb in round one, eventually forcing victory by taking a tight fifth set, and his on-court behaviour came in for close scrutiny too in that match.

Against Jubb, a line judge was prompted to speak to the chair umpire about Kyrgios, whose demands for some fans to be removed were punctuated by spitting towards a section of the crowd upon victory.

Kyrgios spoke after that match of receiving "a lot of disrespect" from the crowds, while he also jousted with journalists in a news conference, before being angered by what he read afterwards.

Sinking Queen's Club runner-up Krajinovic in such a classy fashion was described by the unseeded Kyrgios as his response.

"I was pretty disappointed in my performance in the first round. Then obviously the media's disrespect and just everything, it was just kind of a reminder to put you all back in your place from the performance today," Kyrgios said. "He made finals at Queen's, top 30 in the world, seeded. It's a gentle reminder."

Kyrgios hit 50 winners and made only 10 unforced errors, saying in an on-court interview that he had displayed "great body language".

"I just wanted to remind everyone that I'm pretty good," he said, with a deliberately straight face.

"I'm just happy. I've been working hard and I've been preparing for this tournament. It's been circled on my calendar pretty much all year, and I'm so excited to be here again.

"I think it's my best chance to win a grand slam of all the four [majors], and I'll keep taking it match by match. I've got an incredibly tough draw still, and today I couldn't have played better and now I can just recover and get ready."

Awaiting Kyrgios in round three is Tsitsipas, a straight-sets winner on Thursday against another Australian, Jordan Thompson.

Kyrgios holds a 3-1 winning head-to-head advantage over Tsitsipas in their previous meetings, coming out on top when they met at Halle just a fortnight ago.

That recent match means Tsitsipas has it fresh in his mind what it might take to topple Kyrgios, and the Greek fourth seed told a news conference: "He claims to like grass and his game is good for the grass.

"I am thrilled to be facing him. I respect him a lot on the court and what he is trying to do. Even though he has been a little controversial in the past, I think he's playing good tennis.

"I'm going to concentrate on doing my own thing and pay attention to my own game from start to finish. Hopefully I can have a great competitive match against him."

Wimbledon lost another seed to a positive COVID-19 test on Thursday as former semi-finalist Roberto Bautista Agut pulled out of the tournament.

The Spaniard, who lost in four sets to Novak Djokovic in their 2019 last-four tussle, announced his withdrawal as play got under way on day four at the All England Club.

Bautista Agut wrote on Twitter: "Today I notified @Wimbledon of my withdrawal. I have tested positive for Covid-19. Fortunately, the symptoms are not very serious, but I think it is the best decision. Thank you for your support. I hope to come back soon."

Now aged 34, Bautista Agut was the 17th seed at the championships and had been due to play Colombian Daniel Elahi Galan on Court Three on Thursday afternoon.

Galan receives a walkover into the third round as a result of Bautista Agut's announcement.

The loss of Bautista Agut follows the crushing blow of last year's runner-up Matteo Berrettini having to abandon his Wimbledon mission for the same reason.

Eighth seed Berrettini recently won at Queen's Club for the second straight year and was widely considered a credible challenger to Novak Djokovic and Rafael Nadal, but the Italian pulled out ahead of his first-round match on Tuesday.

Croatian Marin Cilic, a former US Open champion and Wimbledon runner-up, also withdrew from the tournament before his opening match after a recent positive test.

Andy Murray's Wimbledon journey has ended in the second round despite a spirited fightback against John Isner in a four-set thriller.

The three-time grand slam champion - two of which have come at SW19 - will not add a fourth to his collection after he was downed by the big-serving American 6-4 7-6 (7-4) 6-7 (3-7) 6-4 on Centre Court on Wednesday.

Yet the 35-year-old did not go down quietly against the number 20 seed, forcing a tie-break in the third set to prevent a straight-sets win for his opponent before ultimately fading in the fourth.

For Murray, it marks the earliest exit of his Wimbledon career, having previously always reached the third round at senior level.

Despite never dropping more than two games behind Isner across the contest, the Scot was crucially never able to break serve. 

Isner sent down a stunning 36 aces, including three in succession in the final game of the match to put him on the brink of victory, before a neat backhand over the net sealed the deal.

Novak Djokovic says he will support his former coach Boris Becker and the German's family in any way he can during his time in prison.

Becker was jailed for two-and-half years at the end of April after being found guilty of concealing £2.5million of assets to avoid paying money he owed after his bankruptcy.

The six-time grand slam champion's girlfriend, Lilian de Carvalho Monteiro, and his son, Noah, were in Djokovic's box on Centre Court for his first and second-round matches at Wimbledon.

Djokovic had Becker in his corner for three years as his coach until the end of 2016.

The legendary Serbian has not been in direct contact with Becker, but vowed after outclassing Thanasi Kokkinakis at SW19 on Wednesday that he will always be there for the 54-year-old and his relatives.

He said during a media conference at the All England Club: "I haven't been communicating directly with him, but I've been communicating to him through them [Becker's family] and I was really glad to have hosted his girlfriend and his son Noah for my first round and now today second-round match.

"Noah and his younger brother, Elias, are going to visit Boris I think in the next few days for the first time since he went to prison and I've been just trying to give support to people around him, his closest people, his family members because I consider Boris as a family member. He's someone that I greatly appreciate, respect and care about.

"We've been through a lot together and during those three years of collaboration and our relationship dates back even before that. After we finished our professional relationship we always stayed close; him with my team, my agents and my family.

"It breaks my heart to see what is happening to him, so this is a little gesture of friendship to invite them. He knows and they now they can always count on me for whatever support or help I can provide."

Defending champion Novak Djokovic outclassed Thanasi Kokkinakis in a domineering straight-sets victory to march into the third round at Wimbledon.

The top seed moved majestically as he made a statement on Centre Court, winning 6-1 6-4 6-2 in just two hours on Wednesday.

Djokovic breezed into a 3-0 lead in an opening set he served out to love after breaking for a second time, returning majestically as he dominated the Australian.

The 20-time grand slam champion needed just the one early break in the second set as he served superbly and was ruthless at the net, while also bossing rallies from the back of the court.

World number three Djokovic was relentless as he broke twice in a one-sided third set before ending the match with a hold after saving the only break point he faced.

Six-time Wimbledon champion Djokovic will face fellow Serbian Miomir Kecmanovic in round three at the All England Club.

Data slam: Djokovic near flawless as he extends winning run to 23

That is 23 wins in a row at the grass-court grand slam for three-time defending champion Djokovic.

The tournament favourite dropped a set in his win over Kwon Soon-woo on Monday, but barely put a foot wrong two days later.

Alize Cornet claims several players contracted COVID-19 at last month's French Open, but kept the outbreak quiet in order to avoid mass withdrawals from the tournament.

Wimbledon has already been rocked by two high-profile male players withdrawing after testing positive for the virus, with last year's runner-up Matteo Berrettini and 2014 US Open champion Marin Cilic both pulling out ahead of scheduled first-round matches on Tuesday.

Now Cornet, who equalled Ai Sugiyama's all-time record of 62 consecutive grand slam main-draw appearances in a win over Yulia Putintseva on day two, claims there were cases at Roland Garros that did not come to light.

"At Roland Garros, there was a Covid epidemic, no one talked about it. In the locker room, everyone got it and we said nothing," she told L'Equipe.

"When it comes out in the press, with big players, it will start to set fire to the lake everywhere and that worries me a little.

"[2021 French Open winner Barbora] Krejcikova withdrew saying she had Covid, and the whole locker room was sick. 

"At some point, we all might have had the flu. The thing is, we have the symptoms, itchy throat… we play and everything is fine, it's fine. 

"At Roland, I think there have been a few cases and it's a tacit agreement between us. We are not going to self-test to get into trouble! 

"Afterwards, I saw girls wearing masks, maybe because they knew and didn't want to pass it on. You also have to have a civic spirit."

Rafael Nadal was delighted to pass an "important test" against Francisco Cerundolo in his Wimbledon opener and refused to blame his foot injury after dropping the third set against the Argentine.

Nadal was made to work on Centre Court on Tuesday, requiring three hours and 33 minutes to wrap up a 6-4 6-3 3-6 6-4 win over Cerundolo.

The 22-time grand slam champion made 41 unforced errors but regained his composure to move into the second round, winning 11 consecutive points as he fought back from a break down in the fourth set to ensure he will face Ricardas Berankis.

The Spaniard says his lack of action on grass was always going to ensure it would not be plain sailing at SW19.

"I'm going to be talking about my foot today and not anymore, if it's fine for you guys," said the second seed, who is in the hunt for a calendar Grand Slam.

"We cannot be talking about my foot every single day. If not, we forget the most important thing: that is tennis.

"All credit to Fran, he started to play great and he has been a very tough opponent.

"Grass is not a surface we play very often and especially in my case, for different reasons, the last three years I didn't put a foot on the grass.

"It always takes a while – this has been my first match and every day is a test and today has been one of those important tests.

"At the beginning of the tournament, especially under the circumstances that I arrived here, the victory is the most important thing because that gives me the chance to practice tomorrow again and to have another match in two days, and I'm happy for that, without a doubt."

Nadal played his first grass-court match in three years just last week when facing Stan Wawrinka in an exhibition contest, and is participating at the All England Club for the first time since a run to the semi-finals in 2019.

Rafael Nadal was forced to work for a first-round victory over Francisco Cerundolo on Centre Court at Wimbledon.

The world number two overcame a scare to secure a 6-4 6-3 3-6 6-4 win at SW19 despite making 41 unforced errors as he eyes a first calendar Grand Slam.

Second seed Nadal, who won his first grass-court match in three years in an exhibition match against Stan Wawrinka last week, secured a break in the fourth game but Argentine Cerundolo immediately responded, finishing with a strong overhead volley after the Spaniard lost his footing after his service.

Cerundolo was certainly not fazed by his all-conquering opponent, with the pair exchanging thrilling rallies and both displaying an array of brilliant shots in a first set that Nadal won by breaking for a second time.

The 22-time major champion made a scrappy start to the second set, but a solitary break in the sixth game put him one set away from round two.

In the third, Cerundolo continued to battle as he broke Nadal back immediately to peg him back at 2-2 and edged in front at 5-3 before serving out the set to raise hopes he could pull off a huge shock.

The world number 42 continued to excel as he opened up a 3-1 lead in the fourth set, but Nadal roared back and won 11 consecutive points, breaking twice to seal his spot in the second round without being taken the distance.

He will face Ricardas Berankis in the second round at the All England Club.

Data slam: Nadal matches Navratilova record

Nadal's victory saw him equal the great Martina Navratilova's record of 306 grand slam wins in his career.

That puts him joint-fourth on the all-time list, behind only Roger Federer (369), Serena Williams (365) and Novak Djokovic (328)

WINNERS/UNFORCED ERRORS
Nadal – 23/41
Cerundolo – 30/46

Feliciano Lopez equalled Roger Federer's record of 81 main-draw appearances at grand slam events in the Open era but he was beaten in the first round at Wimbledon.

The 40-year-old made his grand slam debut at the 2001 French Open and had appeared in every major since the 2002 event in Paris until he failed to progress through qualifying at Roland Garros this year.

Spaniard Lopez went down in straight sets to Botic van de Zandschulp at SW19 on Tuesday.

Ranked 214 in the world, Lopez is a three-time quarter-finalist at the All England Club, while he also reached the quarter-finals of the US Open in 2015.

Since then, the veteran has never progressed further than the third round at a grand slam.

Fabrice Santoro is third on the list behind Federer and Lopez with 70 main-draw appearances at majors, with Mikhail Youzhny and Fernando Verdasco on 69.

Nick Kyrgios hit out at a "rowdy" Wimbledon crowd after coming through a five-set thriller with Brit Paul Jubb in the first round.

The Australian was forced to come from behind to avoid a surprise exit, ultimately prevailing 3-6 6-1 7-5 6-7 (3-7) 7-5 on No.3 Court on Tuesday.

In a typically tempestuous performance, the world number 40 was frustrated by certain members of a partisan home crowd.

Kyrgios also accused a line judge of being a "snitch" as he aimed his grievances at the chair umpire, also calling for vocal spectators to be ejected.

The 27-year-old let his feelings be known after wrapping up his victory in just over three hours and paid tribute to his opponent.

"It was tough, he's a local wildcard, had nothing to lose and he played exceptional tennis at times," he stated. "He's going to be a good player for sure, I'm just happy to get through.

"The crowd was pretty rowdy. A couple of people were not shy in criticising me so that one is for you, you know who you are.

"Playing here is a lot of fun, Wimbledon over the last couple of years has been strange. We had bubbles last year and no ranking points this year, but it's special.

"It would've been a tough loss to take and I'm happy to get through. I just talk a lot on the court but off the court I'm not too bad."

Kyrgios will face either Serbia's Filip Krajinovic or the Czech Republic's Jiri Lehecka in the second round on Thursday.

Andy Murray has defended using an underam serve in his four-set Wimbledon victory over James Duckworth and believes the tactic should be seen as smart.

The two-time Wimbledon champion recovered from a set down to win 4-6 6-3 6-2 6-4 against the Australian on Monday.

Murray maintained his record of having never lost in the first round at SW19, throwing in an underarm serve to help him win a point in the third set.

The Scot insisted using the underam serve, a move often associated with Duckworth's compatriot Nick Kyrgios, is a legitimate tactic and not a sign of disrespect to an opponent.

"He changed his return position, that's why I did it," Murray explained after the match. 

"He was struggling a little bit on the first-serve return, so he stepped probably two metres further back. As soon as I saw him step further back, I threw the underarm serve in.

"I personally have no issue with players using it. I never have. Certainly more and more players have started returning from further behind the baseline now to give themselves an advantage to return.

"No one says it's disrespectful for someone to return from five or six metres behind the baseline to try to get an advantage.

"So I used it, not to be disrespectful to him, but to say, 'if you're going to step further back to return the serve to give yourself more time, then I'm going to exploit that'.

"I've never understood that [argument it is disrespectful]. It's a legitimate way of serving.

"I would never use an underarm serve if someone was standing on the baseline because I think it's a stupid idea because they're going to track it down and it's easy to get.

"If they stand four or five metres behind the baseline, then why would you not do that to try to bring them forward if they're not comfortable returning there? Tactically, it's a smart play."

Murray will face big-serving American John Isner in the second round on Wednesday, having won each of the duo's eight previous head-to-head meetings.

He was happy with how he felt physically after beating Duckworth, having returned from the abdominal injury he suffered while reaching the Stuttgart Open final earlier this month.

"The last few days when I've been serving was fine," he said. "I went to get an ultrasound scan on it on Saturday after my practice just to see how it was progressing.

"It was all clear for the first time on the scans, which is really positive. I wanted that kind of for my own peace of mind to know that the injury has healed. 

"Obviously I still need to take precautions and still do some rehab and protect it when I can, but in the match it was absolutely fine."

Andy Murray said he intends to make the most of every appearance on Centre Court after recovering from one set down to beat James Duckworth in his Wimbledon opener.

Two-time Wimbledon champion Murray took two hours and 43 minutes to record a 4-6 6-3 6-2 6-4 win over the Australian, maintaining his record of having never fallen at the first hurdle in SW19.

Murray is making just his second Wimbledon appearance since 2017 and is looking to better last year's run to the third round, where he suffered a straight-sets reverse against Denis Shapovalov.

Having endured a spate of injuries and undergone two hip surgeries since his last Wimbledon triumph in 2016, the 35-year-old said he will enjoy every opportunity he gets to play in front of a home crowd on Centre Court.

"It's amazing to be back out here again with a full crowd after the last few years, amazing atmosphere," he said.

"Obviously I'm getting on a bit now, so I don't know how many more opportunities I'll get to play on this court. I want to make the most of every time I get to come out here now.

"I'm glad I managed to get through and hopefully I'll get another match on here in a couple of days."

After fighting back to beat the world number 74, Murray expressed his hope he could grow into the tournament as he advances. 

"I thought I did well to rebound after the first set, he likes playing on the grass, he's come back from a hip surgery himself in January and was playing very well," he added.

"Once I started to find my returns a little bit more as the match went on, I felt a bit more comfortable and did well to get through.

"Naturally, there's always nerves and pressure and butterflies and stress and all of those things before the first match, it was a longer build-up for me than usual because of the ab injury I had after Stuttgart [where Murray finished as runner-up earlier this month].

"I've done a lot of practising here, I've been at the venue a lot in the last couple of weeks so yeah, it was great to get out here, get a win under my belt and hopefully I'll play better from here on in."

Murray will face big-serving American John Isner in the second round on Wednesday, having won each of the duo's eight previous head-to-head meetings.

Carlos Alcaraz insisted he is not feeling any pressure to be among the Wimbledon favourites after coming through a marathon four-hour clash with Jan-Lennard Struff to reach the second round.

Alcaraz, whose four Tour-level titles in 2022 are more than any other player on the ATP Tour, has been tipped for a deep run at Wimbledon after surging to seventh in the world rankings.

But the 19-year-old was on the brink of a stunning first-round exit when he was taken to a fourth-set tie-break at 2-1 down on Monday, eventually recovering to post a gruelling 4-6 7-5 4-6 7-6 (7-3) 6-4 win on No. 1 Court.

In his post-match media conference, the Spaniard reiterated last week's claim that he is not one of the favourites to triumph in London, although he said he could win the tournament if he plays to the best of his ability.

"I don't feel the pressure because I don't rank myself as one of the favourites to win this tournament," Alcaraz said.

"Obviously if I play well, I have [the] level to win the tournament, but there are a lot more experienced players on grass. I don't feel the pressure."

Alcaraz also conceded his grass-court game can still improve as he hailed his tremendous serving display – which brought him 30 aces, as the reason for his victory.

"I enjoyed [the match] a lot," he added. "Great battle over four hours. For me, [to] play on grass is so beautiful. I like to play on grass. 

"I would say my level on grass has to improve a little bit, but I'm happy with my level.

"I didn't expect to move as well as I did. I mean, I played really well, I felt really well playing on grass and I still don't know how I served [so well].

"This is probably my best match serving. This was a weapon that I used [and] that's why I won – the serve, for sure."

Alcaraz will face Tallon Griekspoor in the second round after the Dutch player overcame Fabio Fognini in four sets on day one.

Hubert Hurkacz sent down 21 aces in his first-round match at Wimbledon, enough to raise €2,100 for the people of Ukraine but not enough to reach the second round.

The seventh seed, who was a semi-finalist at the All England Club last year, promised on the eve of the championships to donate €100 in aid for every one of his aces.

"Hope my serve works well," Hurkacz wrote on Twitter, and it certainly did across five sets against Alejandro Davidovich Fokina.

Having averaged 11.6 aces per match this season – his 452 the third most on the ATP Tour – Hurkacz had 21 to just three double faults in an effective serving display on Monday.

Unfortunately, Davidovich Fokina was still able to pull off an early upset, narrowly advancing 7-6 (7-4) 6-4 5-7 2-6 7-6 (10-8).

This was the third top-10 win of Davidovich Fokina's career but the first on grass, with his previous two such victories both coming at the Monte-Carlo Masters (vs Matteo Berrettini in 2021 and versus Novak Djokovic in 2022).

While Hurkacz will not add to his ace tally, John Isner undoubtedly will.

He had a remarkable 54 in his five-set win against Enzo Couacaud – as many as Hurkacz managed across six matches in his 2021 run to the last four.

The last player to record 50 or more aces in a grand slam match had also been Isner, against Steven Johnson at the 2020 US Open.

Novak Djokovic became the first male player in the Open Era to win at least 80 matches in all four grand slams with victory over Kwon Soon-woo in the first round of Wimbledon.

The world number three, who is seeking a seventh crown at SW19 to take him level with Pete Sampras and behind only Roger Federer (8), advanced 6-3 3-6 6-3 6-4 on Monday.

That was Djokovic's 80th win at the All England Club in what was his 90th match, adding to his 85 wins at the French Open, 82 at the Australian Open and 81 at the US Open.

He has won 22 matches in a row at Wimbledon since retiring in his quarter-final with Tomas Berdych in the 2017 quarter-finals, and is 17-0 in first-round matches in the event.

With 328 grand slam wins to his name, Djokovic is second only to Federer (369) in that regard, with fellow heavyweight Rafael Nadal – in action on Tuesday – boasting 305 wins.

"I am as dedicated as anyone out there," Djokovic, playing his first match on grass this year, said in his interview on Centre Court. "Now that we're at 80, let's get to 100.

"I'm not one of the youngsters any more, but the love for this sport still burns in me and I try to play my best tennis at the grand slams and deliver my best at the best courts. 

"I've said this before but this court is truly special. For me it has always been the court I dreamed of playing and winning and all my childhood dreams came true here.

"It's an honour and pleasure to be back on Centre Court. This sport has given me everything. I owe a lot to the sport and I love it still with all my heart."
