Sinner steadies through technical delays to beat Gabriel Diallo in Cincinnati
Sinner overcame LED failures and a fire alarm to beat Gabriel Diallo 6-2, 7-6(6) in Cincinnati. Win.

Jannik Sinner endured an evening of interruptions on Center Court at the Cincinnati Open but advanced with a 6-2, 7-6 (6) victory over Gabriel Diallo. The world No. 1 and 2024 champion began a night session already delayed by a lengthy power outage on Monday and then dealt with malfunctioning LED screens and a fire alarm during play. The match lasted one hour and 52 minutes.
Sinner opened the tournament with a dominant win over Daniel Elahi Galán, losing just two games, yet Gabriel Diallo offered a much stiffer challenge. The 23-year-old Canadian reached a career-high of No. 35 after beginning the season outside the Top 80. Diallo broke through on clay with a run to the quarterfinals of the Mutua Madrid Open, won his first ATP title at the Libéma Open in ‘s-Hertogenbosch, and pushed Taylor Fritz to five sets at Wimbledon.
Diallo jumped to a 2-0 lead to open the match before Sinner, the reigning Australian Open, Wimbledon, and US Open champion, produced a run of six consecutive games. Sinner recovered from 15-40 to serve out the first set.
The second set was interrupted by the fire alarm but resumed with both players holding serve. Sinner won a tight eighth game to level the set at four-all. Diallo answered with a well-struck drop shot and saved the first break point of the set to move twice within a game of forcing a decider.
In the tiebreaker Sinner took the first two points but trailed 4-2 later on. Diallo won a first set point that he could not convert, ultimately netting a volley and presenting match point to Sinner. The top seed closed the match with an ace.
Sinner will next face the winner of the third-round match between No. 13 seed Tommy Paul (Sinner leads 4-1) and Adrian Mannarino (Sinner leads 3-0).

Rublev rallies past Popyrin in three-and-a-half hour Cincinnati classic
Rublev edged Popyrin 6-7 (5), 7-6 (5), 7-5 in 3.5 hours; saved five of six break points. Cincinnati.

Andrey Rublev survived a marathon to reach the round of 16 at the Cincinnati Open, prevailing in a three-and-a-half hour test against Alexei Popyrin. The No. 9 seed recovered after losing the first set to edge 21st-seeded Popyrin, 6-7 (5), 7-6 (5), 7-5.
Popyrin produced 20 aces and Rublev nearly matched him with 18, but a late break proved decisive. At 6-5, 30-0 for Popyrin, Rublev delivered a telling sequence of returns to take the game and swing the match his way. “I was trying to fight, to keep believing. In the end, somehow out of nowhere at 6-5, 30-0 for him, I make amazing returns. I was able to break him,” Rublev told Prakash Amritraj during a live interview on Tennis Channel. “Both of us deserved to win.”
Rublev saved five of the six break points he faced and moved on after a comeback that continued a theme of recent rematches at the Lindner Family Tennis Center. In the second round he reversed a recent loss to Learner Tien, flipping the script after the American had prevailed in Washington, D.C. The victory over Popyrin was Rublev’s first match against the Australian since their 2024 Montreal final, a result the Russian has had in mind.
His next opponent, Francisco Comesana, stunned Reilly Opelka 6-7 (4), 6-4, 7-5 to advance. Comesana also beat Rublev in the first round at Wimbledon last year, and Rublev acknowledged the pattern in the draw. “It’s gonna be a great challenge for me, because I lost to him the only time we played each other last year in Wimbledon. Looks like this tournament, the draw are rematches,” he said. “First match with Tien, today with Alexei, now again Comesana. I am facing all the players that I lost to. Let’s see where I can get.”
Players have also remarked on the tournament’s extensive renovations. Rublev called the changes “a huge upgrade” and praised the new food access and facilities. © Anita T. Aguilar

Alcaraz reaches 50 wins in 2025, extends rare four-year streak
Alcaraz reached his 50th win with a 6-4, 6-4 victory over Medjedovic in Cincinnati today. He is 22.!

Carlos Alcaraz moved to 50 match wins for the year with a straight-sets victory at the Cincinnati Open, defeating Hamad Medjedovic 6-4, 6-4 on Tuesday. The 22-year-old had been pushed to three sets two days earlier, but produced a cleaner performance against his fellow 22-year-old to register the milestone.
Alcaraz is the first player, male or female, to reach 50 wins in 2025. On the men’s tour Alexander Zverev has the next-most wins with 40, while on the women’s side Aryna Sabalenka leads with 49. Jessica Pegula can move closer to that group: she would notch her 38th victory of the year if she wins her third-round match against Magda Linette tonight.
The win in Cincinnati also continued two longer-running threads. With his victory over Medjedovic, Alcaraz remains unbeaten against players younger than him; he is now 10-0 versus younger opponents. More broadly, Alcaraz is the only man to record 50 or more match wins in each of the last four seasons. No other male player can join him in that distinction, because he was the only man to reach 50 wins in 2022, 2023 and 2024.
There is one woman who can match that four-year consistency: Iga Swiatek. Swiatek won 67 matches in 2022, 68 matches in 2023 and 64 matches in 2024, the only woman with those three totals in that span.
Alcaraz’s Cincinnati victory is therefore both a stand-alone milestone and another entry in a sustained run of high-volume winning. The 50th win underscores his place at the top of the season-long charts and highlights how few players, male or female, have combined volume and consistency across multiple seasons.

Dimitrov Withdraws From US Open After Wimbledon Chest Injury
Dimitrov withdrew from the US Open after tearing a chest muscle at Wimbledon; Tabilo takes his spot.

Grigor Dimitrov has withdrawn from the US Open after suffering a torn chest muscle at Wimbledon. The 34-year-old Bulgarian, a three-time Grand Slam semifinalist, was forced to quit his July 7 match against Jannik Sinner after taking the opening two sets and sustaining the injury in the third.
The withdrawal continues an unbroken sequence of incomplete Grand Slam appearances for Dimitrov. The Wimbledon exit marked the fifth consecutive Grand Slam in which he did not finish a match. That sequence includes the Australian Open in January and the French Open in May of this season, as well as last year’s Wimbledon and US Open.
A year ago at Flushing Meadows, Dimitrov stopped while trailing 6-3, 6-7 (5), 6-3, 4-1 against Frances Tiafoe in the quarterfinals. His best Grand Slam results remain semifinals at the US Open in 2019, the Australian Open in 2017, and Wimbledon in 2014.
Dimitrov reached a career-high ranking of No. 3 and is currently ranked No. 21. Organizers confirmed that Alejandro Tabilo will move into the men’s singles draw in Dimitrov’s place. The US Open men’s singles bracket begins play on Aug. 24.
The withdrawal reduces the field and hands a late opportunity to Tabilo, while marking a notable and unfortunate run of interrupted major campaigns for one of the tour’s long-standing performers.
