Carlos Alcaraz clinched the Cincinnati Open 2025 title after Jannik Sinner withdrew from the final due to illness, with the score at 5-0 in the first set, in a match held on August 18 at the Lindner Family Tennis Center in Mason, Ohio. The world number 2, Alcaraz, secured his first trophy at the Masters 1000 event, bolstering his status as a favorite for the US Open, starting August 24. Sinner’s unexpected withdrawal, as the current ATP number 1 and 2024 champion, stunned fans filling the stands, halting what promised to be another intense chapter in the rivalry between the two young tennis stars. The Spaniard, who dominated the match’s start, capitalized on his opponent’s vulnerability to secure the win, though he expressed solidarity with his rival. The unusual outcome marks Alcaraz’s sixth title of the season and extends his lead in their head-to-head record.
The match began with Alcaraz setting a blistering pace, breaking Sinner’s serve in the first three games. The Italian, known for his consistency on hard courts with 26 consecutive wins this season, appeared off-balance, committing unforced errors and showing physical discomfort. After the fifth game, Sinner signaled to the medical team that he could not continue, abruptly ending the match. The decision raised concerns, especially with the US Open looming, where Sinner defends his title.

- Initial performance: Alcaraz won all five games played, with three service breaks.
- Sinner’s condition: The Italian reported feeling unwell, with no immediate details on the cause.
- Fan expectations: The crowd anticipated a competitive match, disappointed by the early end.
- Calendar impact: Sinner’s withdrawal raises doubts about his US Open preparation.
The victory solidifies Alcaraz’s stellar 2025 season, with 53 wins in 59 matches, including titles at Roland Garros and Rome. The Cincinnati tournament also marks a redemption for the Spaniard, who was runner-up in 2023, losing to Novak Djokovic in a memorable final.
Alcaraz’s early dominance in the final
Alcaraz entered the court determined to impose his aggressive game, leveraging his powerful forehand and quick movement. In the five games played, he displayed precision in his shots and capitalized on Sinner’s errors, who seemed uncomfortable from the start. The 5-0 scoreline in just 20 minutes reflected the Spaniard’s momentary superiority.
Sinner, in contrast, found no tactical or physical answers. His flat groundstrokes, typically a strength on hard courts, lacked power, and his movement was visibly limited. The decision to retire came after a brief consultation with the medical team, prioritizing his health ahead of the US Open.
- First game: Alcaraz broke Sinner’s serve with a crosscourt forehand winner.
- Third game: Sinner committed a double fault, easing the second break.
- Fifth game: Alcaraz sealed the game with an ace, holding serve to love.
- Sinner’s response: The Italian attempted an ace to avoid the third break but failed.
The crowd, expecting a high-level clash, was surprised by the swift conclusion but applauded Alcaraz’s gesture as he approached the net to shake Sinner’s hand and wish him a speedy recovery.
Historic rivalry between Alcaraz and Sinner
The Cincinnati final was the 14th meeting between Alcaraz and Sinner, with the Spaniard extending his head-to-head lead to 9-5. Dubbed the “Sincaraz Era” by fans, their rivalry is marked by intense, high-quality matches, comparable to historic clashes between Federer, Nadal, and Djokovic. In 2025, the two faced off in four finals, with Alcaraz winning in Rome and Roland Garros, while Sinner prevailed in Wimbledon.
In Rome, Alcaraz dominated with a 7-6(5), 6-1 victory, exploiting the clay surface to neutralize Sinner’s aggressive play. At Roland Garros, the five-set final, lasting nearly five and a half hours, was one of the season’s most thrilling, with Alcaraz prevailing in the fifth-set tiebreak. In Wimbledon, Sinner staged a comeback after dropping the first set, winning 4-6, 6-4, 6-4, 6-4 to claim his first title there.
- Rome 2025: Alcaraz won convincingly, dominating the second set.
- Roland Garros 2025: Epic final decided in the fifth-set tiebreak.
- Wimbledon 2025: Sinner overcame Alcaraz in four sets to win London.
- Cincinnati 2025: Alcaraz won by withdrawal, leading 5-0 in the first set.
The rivalry promises more chapters at the US Open, where both are favorites. Sinner’s withdrawal, however, raises questions about his physical condition for the Grand Slam, while Alcaraz gains momentum with the title.
Path to the final
Alcaraz had a solid campaign in Cincinnati, facing tough opponents. In the first round, he defeated Damir Dzumhur in three sets, overcoming a shaky second set. In the quarterfinals, he outlasted Andrey Rublev in a three-set battle, showcasing resilience against the Russian’s aggressive style. In the semifinals, he faced Alexander Zverev, who also had physical issues, allowing Alcaraz a 6-4, 6-3 victory. The Spaniard stood out for his consistency and ability to raise his level in crucial moments.
Sinner, meanwhile, had a smoother path to the final. Without dropping a set, he defeated players like Daniel Elahi Galan, Adrian Mannarino, and Térence Atmane, the latter in the semifinals, marking his 200th hard-court win. His campaign reinforced his dominance on the surface, but the illness in the final halted his 26-match winning streak.
- Alcaraz’s opener: Win over Dzumhur, with a scare in the second set.
- Quarterfinal vs. Rublev: Intense match, with Alcaraz prevailing in three sets.
- Sinner’s semifinal: Victory over Atmane, with a tiebreak in the first set.
- Sinner’s milestone: 200th hard-court win, celebrated on his birthday.
The contrasting performances suggested a balanced final, but Sinner’s physical condition shifted the outcome, giving Alcaraz an unprecedented victory.
Repercussion and US Open expectations
Sinner’s withdrawal sparked concern among fans, especially with the US Open starting August 24. The Italian, the defending champion, has an impressive hard-court record, with 31 wins and only three losses in 2025. His team has not yet clarified the cause of the illness, but speculation points to possible fatigue or dehydration, common in high-temperature tournaments.
Alcaraz expressed solidarity but did not hide his satisfaction with the title. “It’s a shame the match ended this way, but I’m happy to win Cincinnati. I wish Jannik the best for the US Open,” he said. The victory positions him as a top favorite for the Grand Slam, where he seeks his second title after winning in 2022.

The win narrows the ATP ranking gap with Sinner, who leads with 11,480 points to Alcaraz’s 9,580. With the 2024 US Open points expiring, Alcaraz could take the top spot depending on his performance in New York.
The title also marks Alcaraz’s redemption in Cincinnati, where he was runner-up in 2023, losing to Djokovic in an epic nearly four-hour final. His 2025 campaign, with 53 wins in 59 matches, underscores his consistency and versatility, particularly on hard courts, where he has a 75% career win rate (112 wins, 31 losses).
