Serve Strength and Composure: Sinner Advances in Cincinnati with Eye on Title Defense
Sinner won 31 of 32 points on his first serve in Cincinnati extending his 24-match hardcourt streak.

Jannik Sinner extended an unbroken run on hard courts with a composed victory over Adrian Mannarino at the Cincinnati Masters. The world number 1 defeated the veteran 6-4, 7-6(4) in a match interrupted by rain, advancing into the ATP Tour Masters 1000 quarter-final.
Sinner produced a striking serving performance when it counted. He won 97% of the points when his first serve landed, taking 31 of 32 such points. That efficiency translated to pressure relief on return games, but the raw numbers also highlighted areas for improvement: he landed just 52% of first serves, finding the mark 32 times from 62 attempts.
Mannarino managed the lone first-serve point on Sinner’s delivery at 6-5 in the second set, breaking to force a tie-break. Sinner closed out the match in the tie-break, 7-4, and confirmed he was satisfied with the result as he aims to defend the Cincinnati Masters title. “He’s a tough opponent,” said Sinner. “Very different to all the other opponents. Not only because he is a leftie but also how he hits the ball – it’s very low.
“I struggled a bit to close it out but this can happen in this sport and I’m very happy to be in the next round.”
Sinner’s first serve has been a focal point in his recent development and his coach Darren Cahill described the work done since joining the team. “One thing I did say is, ‘The serve needs to improve. You’re six foot four and you’re a strong lad’,” said Cahill in an interview with the ATP Tour website. “You need to be able to get more miles per hour on that first serve, better direction on that first serve.
“Then not only do you start winning some free points from your first serve, but also your Plus One becomes much more effective. If people can neutralise your serve, you have to work much harder for your points.
“Then his questions came, one after the other ‘How do I get better at the serve? What do I need to do?’ It’s typical of him. He wants to compete. He’s a competition animal.
Cahill also explained how the partnership with Sinner’s other key coach Simone Vagnozzi works as he added: “I work hand-in-hand with Simone, he started about six months before I did, and he has been amazing. He had a vision for where Jannik’s game needed to go and we spent a lot of time together working through what technical changes he had to make.
“Anything from a technical point of view, creating more ways for him to develop finishing skills, with his serve a little bit, his transition skills, all the stuff that all the great champions of the sport have in their arsenal.
“Jannik was already a great player, he was already a top-10 player, he hit the ball great from the back of the court, but he needed to work on more avenues to finish points.
“And so we went to work and we a really fortunate that we have a player who wants to get better every single day, he never settles for where he is at the moment, no matter what he achieves and every time he steps onto the court he is looking to improve as a tennis player.”
Sinner has now won 24 straight matches on hard courts and will seek to extend that run while defending his Cincinnati title.

Tight Cincinnati Finish Could Force Top Players Out of US Open Mixed Doubles
A Monday final in Cincinnati may leave Alcaraz and Sinner unable to play US Open mixed doubles. Now.

A compressed schedule in the lead-up to the US Open has created a practical dilemma for players who progress deep in Cincinnati. The expanded ATP Masters 1000 and WTA 1000 formats mean the Cincinnati tournament can finish on a Monday, leaving little time for finalists to join mixed doubles in New York when that event begins the following Wednesday.
Carlos Alcaraz is due to play alongside Emma Raducanu in the US Open mixed doubles, while Jannik Sinner is scheduled to compete with Emma Navarro. If the Cincinnati final becomes another Alcaraz vs Sinner epic on Monday, neither player may have the appetite to appear in mixed doubles the next day in New York. Rain delays at Cincinnati would add further complication and could decide whether either of the top two men compete in the mixed event.
Iga Swiatek is also progressing in Cincinnati and could face a quick turnaround if she continues her run. Coco Gauff was among those opting against playing in the lucrative mixed doubles event as she has prioritised her preparation for the US Open singles. The two-time Grand Slam winner revealed: “For me, it was just because I know the free week of the US Open is already packed for me, for sponsor things, and it was just like a whole other thing. And I’m very competitive; if I were to lose, I would not be happy,” “So, I didn’t want to waste mental energy on that.
“Then on top of the sponsor stuff, the pre-week, and then knowing that this finished on Monday and potentially having to play on Tuesday. Well, you would have to play on a Tuesday. So I just knew it wasn’t going to work out for me, scheduling-wise.
“It’s just that I plan my sponsor weeks literally like a year out, sometimes a year and a half out. And when this whole thing was coming up, I was already booked and busy.”
Barry Fulcher, the coach referenced in recent coverage, predicted many withdrawals and questioned the event’s standing. He said: “This exhibition event will be great fun, but it is not a Grand Slam and it shouldn’t be viewed as such,” “It’s not just about the prize money and more about removing a mixed doubles Grand Slam opportunity.” “My own personal view, it is all just posturing at the moment and I will be fascinated to see how many of those 16 pairings that were announced a few weeks ago will turn up and play.” “I’d be very, very surprised if a lot of those pairs end up taking to the court and the only reason they would release that list is to get everyone talking about it.” “It’s almost like they have put their names down, but there is no obligation to play.” “For me, the best doubles pairing on that list they released is Sara Errani and Andrea Vavassori and it will be interesting to see if some doubles players who end up playing if the singles players drop out.” “I’m a fan of innovation and trying to bring new things into tennis, but I don’t agree with calling it a Grand Slam event.”
The eight teams in the field of the 2025 US Open Mixed Doubles Championship via direct entry are:
Emma Navarro and Jannik Sinner
Paula Badosa and Jack Draper
Iga Swiatek and Casper Ruud
Elena Rybakina and Taylor Fritz
Amanda Anisimova and Holger Rune
Belinda Bencic and Alexander Zverev
Jessica Pegula and Tommy Paul
Mirra Andreeva and Daniil Medvedev
In addition, six teams received wild cards into the field:
Emma Raducanu and Carlos Alcaraz
Madison Keys and Frances Tiafoe
Olga Danilovic and Novak Djokovic
Taylor Townsend and Ben Shelton
Sara Errani and Andrea Vavassori
Venus Williams and Reilly Opelka

Shelton vs. Lehecka: Cincinnati fourth-round test for an in-form American
Shelton meets Lehecka in Cincinnati fourth round. Shelton’s serve vs Lehecka’s Top-10 wins loom.

Thursday’s late-afternoon match on Grandstand at the Cincinnati Open pairs two contrasting threats: Ben Shelton, riding a surge of momentum, and Jiri Lehecka, the Czech with a habit of taking down top players.
Shelton arrives in Cincinnati as the world No. 6 and on an eight-match winning streak after capturing the biggest title of his career in Toronto last week. The American has won 15 of his last 17 matches and is one victory away from reaching the quarterfinals at back-to-back Masters 1000 events for the first time in his career. The match is scheduled to begin at an estimated 4:30 p.m. ET, Thursday, August 14.
Lehecka, ranked No. 26, brings proven scalps and the capacity to unsettle higher-ranked opponents. He owns eight career wins over Top 10 players, including three this season: victories over Grigor Dimitrov in Brisbane, Carlos Alcaraz in Doha and Jack Draper at Queen’s Club. Those results underline his ability to produce high-level tennis on different surfaces and against varied styles.
The players met once earlier this year in the Stuttgart quarterfinals, where Shelton prevailed 6-4, 6-4. That match was dominated by Shelton’s serve: 18 aces to three double faults, a spotless first-serve record (28/28), and the American never faced a break point or was pushed to deuce in 10 service games.
The matchup sets up as a clash between Shelton’s serving firepower and Lehecka’s track record against elite opponents. On paper, Shelton’s recent form and serving numbers make him a formidable favourite, but Lehecka’s history of Top-10 wins this year suggests he can produce the shots and momentum swings necessary to alter the script. The outcome will likely hinge on whether Lehecka can disrupt Shelton’s serve and whether Shelton can sustain the serving level that decided their previous meeting.

Alcaraz moves into Cincinnati quarters after composed win over Luca Nardi
Alcaraz defeated Luca Nardi 6-1 6-4 in Cincinnati, praised his improvement and moves. on court today

Carlos Alcaraz advanced to the Cincinnati Open quarter-finals with a straight-sets win over Luca Nardi, producing what he called his best performance of the event so far.
The world No 2 beat the 98th-ranked Italian, a 22-year-old competing as a lucky loser, 6-1, 6-4 in the last 16 of the Masters 1000 tournament. Alcaraz broke Nardi twice to take the opening set and then recovered from 2-4 down in the second to reel off four successive games and close out the match.
Alcaraz landed 65% of his first serves, won 83% of first-serve points and 56% of second-serve points. He finished with 10 winners and 10 unforced errors. He had earlier defeated Damir Dzumhur and Hamad Medjedovic in his first two matches in Cincinnati.
“I think this match was the best so far for me in this tournament,” he said in his on-court interview. “At the beginning of the tournament, I just really wanted to get better every day, after every practice and every match.
“I think I’m doing it, which I’m really proud about. I’m just really happy with the way I felt the ball today and the way that I moved.”
Asked about balancing on-court preparation with time off, Alcaraz added: “Well, I just try to take care of both things. It depends, without balance, everything is a mess.
“I think both things are really important to be fresh mentally and to come back to court with the feeling that you really want to have battles, to practice and then to get ready for the tournaments. I think a balance of both is important.”
The victory sends Alcaraz into his third quarter-final in Cincinnati, after runs to the last eight in 2022 and 2023, his best previous result being a runner-up finish in 2023. The 22-year-old has 27 wins in his last 28 matches and is on a 14-match winning streak at ATP Masters 1000 level, a run that includes his titles in Rome and Monte Carlo.
Since Masters events began in 1990, Alcaraz is only the third player to win 14 successive matches at this level before turning 23, following Pete Sampras and Rafael Nadal. He will meet world No 11 Andrey Rublev in the quarter-finals.
