Andrey Rublev dug deep to bring up a major milestone Thursday at Wimbledon, where the seventh seed defeated Aslan Karatsev 6-7(4), 6-3, 6-4, 7-5 for his 50th Grand Slam match win.

Rublev reacted well after dropping the first set to seal a two-hour, 52-minute second-round victory against the World No. 50 Karatsev on Court 2. The 25-year-old claimed the only break of serve in each of the second and third sets before overcoming a late wobble on serve to level the pair’s Lexus ATP Head2Head series at 1-1.

Rublev was broken by Karatsev when serving for the match at 5-4 in the fourth set, but made no mistake the second time around at 6-5 to advance to the third round at Wimbledon for the second time. His opponent as he bids to equal his personal-best showing at the grass-court major, a fourth-round run from 2021, will be wild card David Goffin or qualifier Marcelo Tomas Barrios Vera.

Alexander Zverev and Matteo Berrettini also enjoyed the taste of victory at SW19 on Thursday. The pair both advanced to the second round after finally completing their long delayed openers at the All England Club.

The 19th seeded Zverev impressed on his first appearance at The Championships this year. He downed Dutchman Gijs Brouwer 6-4, 7-6(4), 7-6(5) to reach the second round for the sixth time in seventh Wimbledon appearances. The 26-year-old German, who reached the fourth round in 2017 and 2021, will next play Yosuke Watanuki, who beat Marc-Andrea Huesler 6-7(5), 5-7, 7-6(5), 7-6(3), 6-3.

Berrettini and his countryman Lorenzo Sonego returned to court for the third consecutive day. To complete their first-round clash. Berrettini had led by two sets to one overnight and the 2021 finalist completed a 6-7(5), 6-3, 7-6(7), 6-3 triumph on Court 12 in a match that began on Tuesday afternoon.

With his win, Berrettini avenged his loss to his good friend Sonego on the grass in Stuttgart last month. The 27-year-old Italian will play Alex de Minaur in the second round, after the Australian completed a 6-7(5), 6-3, 6-3, 7-6(2) triumph against qualifier Kimmer Coppejans.

Possessing a swinging lefty serve, a destructive forehand and good touch, it is no surprise #NextGenATP Swiss Dominic Stricker has excelled on the London grass this season. The 20-year-old battled through three rounds of qualifying at Roehampton before he clawed past Alexei Popyrin in five-sets to earn his maiden major win at Wimbledon.

Making his debut at The Championships, Stricker is soaking up the feel-good factor that swirls around SW19 at this time of year.

“It’s amazing to be here,” Stricker told ATPTour.com. “I was playing qualifying in Roehampton and then coming here on the site that I have always seen on TV is amazing. I have seen so many good matches here. It is just an honour to play here on these courts. I’m just super happy to be here and to have one more match.

“I think my game suits grass very well. I played good all of the years that I played on grass. And then now this year with qualifying and then also winning one match, that is already great. But there is more to come.”

Stricker will need to find more if he is to continue his Wimbledon run, with 10th seed Frances Tiafoe his next opponent on Thursday.

The American, who advanced to the fourth round at SW19 last year, recently captured his first grass-court title in Stuttgart, cracking the Top 10 in the Pepperstone ATP Rankings as a result. With Tiafoe demonstrating great court-craft, Stricker knows he will be in for a test.

“It is going to be a great challenge, but I’m going try to do the best I can,” Stricker said ahead of his first Lexus ATP Head2Head meeting against Tiafoe. “He’s an amazing player. I think he’s now in the Top 10 for the first time in his career. It is just amazing to play one of these guys and I’ll try to do my things and hope I will get a few chances and then we will see how the match will go.”

Stricker has not been the only Swiss star on site this week. The record eight-time Wimbledon champion Roger Federer attended play on Tuesday, sitting in the Royal Box alongside wife Mirka and Catherine, the Princess of Wales.

Stricker spent time training with Federer in Dubai in the past, with the former World No. 1 sharing words of advice. The 20-year-old was delighted to see Federer watching the action.

“I’ve seen a lot of matches of Roger here, all of his big finals he played here and all these matches. I remember his win in 2017 [against Marin Cilic]. It’s great that he’s here,” Stricker said. “They did an amazing event for him on Centre Court and it’s just great to see.”

Stricker is currently No. 102 in the Pepperstone ATP Live Rankings and is the only Swiss player to win five ATP Challenger Tour titles before his 21st birthday. The lefty sits seventh in the Pepperstone ATP Live Next Gen Race and is aiming to qualify for the 21-and-under event for the second time after advancing to the semi-finals last year. Stricker feels the experience he gained at the Next Gen ATP Finals has helped him at Wimbledon.

“I think Next Gen was a great event,” Stricker said. “They did such a good event, with so many people coming to support us. I think it was just a great week also to get used to the attention a bit. I would say it helped me a lot for the match against Popyrin. There were a lot of people watching the match and it was great to know before that I would know how to handle it.”

If Stricker can earn his first Top 10 win against Tiafoe on Thursday, he will further boost his chances of returning to the Next Gen ATP Finals this season, which is his goal.

“When I’m doing the right things collecting as many points as possible, that helps, and it’ll be the goal at the end of the year to play Next Gen again because it’s such a great event and I really enjoyed it last year,” Stricker concluded.

Despite a 20-month absence from competition, Kei Nishikori has not missed a beat in his first six matches on the ATP Challenger Tour. Part of the reason why is that the Japanese star stayed connected to the sport.

“I was watching a lot of tennis actually. I thought that was a good idea to be mentally ready to play again,” Nishikori told ATPTour.com. “Also just to remind me how the top players are playing. And I can imagine playing tennis in the head.

“Twenty months was not a short time. I was just trying to be mentally fresh, not stressing too much every day.”

The 33-year-old, who this week is competing in the Cranbrook Tennis Classic in Bloomfield Hills, Michigan, first returned to action last month at the Palmas del Mar Challenger in Puerto Rico, where he dropped just one set en route to the title.

Nishikori quickly found a high level to be crowned champion in Palmas del Mar, where he was playing his first tournament since the 2021 BNP Paribas Open. Throughout the Challenger 75 event, the former World No. 4 produced vintage down-the-line winners and showed deft feel from all corners of the court. By the end of the week, Nishikori had his hands around the trophy.

“That was surprising a lot. I was just expecting to just play one match and just kind of get a rhythm for it,” Nishikori said. “Somehow I played good in the first match and started getting more confident every match. In the final, I think I played pretty good tennis.

“Usually I struggle. I’ve come back many times from injury and it usually takes half a year to be 100 per cent. You lose the confidence, you lose the feeling of the ball, the way to move, you kind of lose everything.

“But luckily, I had a lot of time to practice. This time, I feel already that I’m like 70, 80 per cent. So I’m quite happy about the way I’m playing right now.”

What motivated Nishikori to make a comeback despite various injuries? The Japanese star’s eagerness to get back to the top of his game and have an opportunity to play some of the new faces in the sport.

“I had hip surgery, I sprained my ankle during these 20 months, and my shoulder was bad. So I had a couple of different injuries,” Nishikori said. “That was also why it was tough to maintain the motivation, but I just wanted to play tennis again and compete again. And especially watching Djokovic, Rafa still playing, fighting. And I haven’t played against [Carlos] Alcaraz, [Holger] Rune. That’s something I also can’t wait to play against them.”

After Bloomfield Hills, Nishikori will again compete on the ATP Challenger Tour next week in Chicago, Illinois. Later this month, he will return to ATP Tour action in Atlanta and Washington, D.C.

“I just need to play more matches,” Nishikori said. “I think I just need to play with those Top-50 players again. I just need to get used to playing with those guys and get confidence again. Overall I’m really happy with how I’m playing. I just need to focus and recover well.”

Nishikori will look to continue his comeback in winning fashion Thursday, when he faces third seed Denis Kudla at the Bloomfield Hills Challenger. Fans can live stream all ATP Challenger Tour matches for free and on demand on Challenger TV.

When Thursday’s Wimbledon order of play was released, one notable name was missing: World No. 1 Carlos Alcaraz. That is because of the rain that has wreaked havoc at SW19 early in the fortnight.

Alcaraz won his first-round match Tuesday against Frenchman Jeremy Chardy and will play another Frenchman, Alexandre Muller in the second round. If there had not been rain, the 20-year-old would have been scheduled for Thursday after one day off.

However, the rain has delayed other players in his section. None of Alcaraz’s potential third-round opponents have completed their first-round match yet. 

Nicolas Jarry, the 25th seed, trails Marco Cecchinato 4-6, 4-1. Jason Kubler leads Ugo Humbert 6-4, 4-6, 6-2. Both matches are scheduled second on Thursday.

It is not the only section rain has delayed. There are three first-round matches that have not begun yet: Alexander Zverev against Gijs Brouwer, Alejandro Davidovich Fokina against Arthur Fils and Botic van de Zandschulp against Zhang Zhizhen.

After losing a decisive tie-break to Stefanos Tsitsipas on Wednesday in the Wimbledon opening round, Dominic Thiem maintained a positive outlook. Following the match, a 3-6, 7-6(1), 6-2, 6-7(5), 7-6(10-8) win for the Greek, Thiem’s tournament is over — but he feels his comeback to the top of the ATP Tour is just beginning.

“Obviously it was a great encounter, and to me, I’m leaving with [my] head up,” the 29-year-old said in his post-match press conference. “It kind of showed me that I’m still there. The quality was very, very good. The fighting spirit was really, really good.

“This match showed me a lot of good things that I’m still here, still able to compete with the big boys of the game. Obviously it’s tough, but, well, a tie-break in the fifth is like a penalty shootout. All credit to him as well, how he played in the breaker, and how he saved that break point in the fifth was just unbelievable.”

While Thiem and Tsitsipas also played a final-set tie-break in Madrid earlier this year — again won by Tsitsipas — the Austrian felt more positive about their most recent Lexus ATP Head2Head meeting.

“I needed that, because today also somehow felt different than in Madrid, for example, because the quality was really there today,” said the Austrian, who is now knotted with Tsitipas 5-5 in their series. “How I was feeling on the court in general was just how it should be, and that what makes me happy also looking to the next weeks.”

With his grass-court season now behind him, Thiem is excited to build his game further as the year continues.

“Today definitely I found [my level], and I’m hoping to keep it as well, on any level, on any surface,” he said. “The way I played and the way I stepped on court today, that’s just the only way it should be. I’m trying and working hard to keep it like that on all the remaining year.”
