World No.1 Jannik Sinner produced one of the greatest shocks of the 2025 season by retiring from his Cincinnati Open final match against Carlos Alcaraz. Sinner was down 5-0 in the first set before he called the medical staff, and eventually had to throw in the towel.

Alcaraz, who also played against a medically unfit opponent in his semifinal match, won his first Cincinnati Open title. Sinner shared update on his physical status in the trophy ceremony.

Usually I start with the opponent but today I have to start with you guys. I’m super super sorry to disappoint you. From yesterday I didn’t feel great. I thought I would improve during the night. It came up worse. I tried to come out and make it at least a small match but I couldn’t handle more. I’m very very sorry for all of you. I know some of you on Monday maybe had to work or do something else, so I’m very very sorry. Of course Carlos congrats. Another title. Not the way you wanted to win but it’s amazing what kind of season you’re producing. You and your whole team are doing amazing. Keep it up. I wish you only all the best for the U.S. Open and the rest of the season.

Sinner’s preparations for the US Open have been brought under a microscope. Moreover, he is in danger of relinquishing his spot in the US Open mixed doubles format starting on Tuesday.

The two-week Masters 1000 event format and the heatwave at Cincinnati has triggered criticism from all the tennis fraternity. Seeing the physical state of Sinner will only add fuel to the fire.

Carlos Alcaraz and Jannik Sinner make US Open decision

Jannik Sinner and Carlos Alcaraz have officially confirmed their entries in the new-look US Open mixed doubles. The top two players in men’s tennis will both feature in the draw, ending speculation about possible withdrawals.

Their involvement seemed in doubt during the Cincinnati Masters final run. Sinner’s situation was even more uncertain after Emma Navarro pulled out as his partner on Saturday. Despite that, tournament organizers announced a star-studded lineup that includes both young champions.

Alcaraz will pair with 2021 US Open winner Emma Raducanu, and they face a blockbuster opener against Jessica Pegula and Jack Draper. Novak Djokovic returns for his first match since Wimbledon, partnering with Olga Danilovic against Daniil Medvedev and Mirra Andreeva.

Other headline teams include Iga Swiatek joining Casper Ruud to face Madison Keys and Frances Tiafoe. Naomi Osaka will partner Gael Monfils against Caty McNally and Lorenzo Musetti, while Venus Williams teams up with Reilly Opelka in another high-profile match.

Carlos Alcaraz wins first Cincinnati Open title as Jannik Sinner retires

Carlos Alcaraz claimed his sixth title of the year at the Cincinnati Open on Monday after Jannik Sinner retired just 23 minutes into the final. Struggling in the extreme heat, the defending champion trailed 0-5 in the opening set before calling for medical attention and deciding he could not continue.

With the win, Alcaraz secured his 22nd career trophy and boosted his chances of finishing the season as year-end No.1. He now leads Sinner by 1,890 points in the PIF ATP Live Race to Turin, strengthening his position ahead of the closing stretch of the season.

The loss ended Sinner’s 26-match winning run on hard courts. His immediate focus will be on recovering in time for the US Open, where he is the defending champion. His scheduled mixed doubles campaign with Katerina Siniakova, set to begin Tuesday, is also uncertain.

For Alcaraz, the triumph carried extra meaning. Last year, he missed out on the trophy after losing a classic final to Novak Djokovic. This time, he lifted his eighth Masters 1000 title, a tally that places him second only to Djokovic among active players.
