A Final That Never Was
The defending champion pulled out with illness, raising questions about his preparations before next Sunday’s US Open, as Alcaraz raced into a 5-0 lead in the first set when an out-of-sorts and emotional Sinner announced that he was unable to continue. What was expected to be another classic encounter between tennis’s two brightest stars became a moment of genuine concern and sportsmanship.
“I’m super super sorry to disappoint you. I tried to come out, trying to make it, at least a small match, but I couldn’t handle more so I’m very, very sorry for all of you,” Sinner said after the match, having begun to feel unwell the night before. The Italian appeared visibly distressed as he addressed the disappointed crowd at the Lindner Family Tennis Center.
Alcaraz’s Gracious Victory
Despite the circumstances, Carlos Alcaraz handled the situation with remarkable maturity and empathy. “This is not the way that I want to win trophies, I just have to say sorry, I can understand how you must feel now,” Alcaraz told Sinner during the presentation ceremony. The 22-year-old Spaniard was seen consoling his rival on the bench and even signed the television camera lens with “Sorry Jannik” as a gesture of support.
“I’m so sorry for Jannik!” Alcaraz wrote on X. “Nobody likes to win because their opponent retires, especially in a final like this. Wishing you a speedy recovery! Very happy with my week in Cincinnati and feeling ready for the US Open.”
Record-Breaking Achievement
This victory marks several significant milestones for Carlos Alcaraz:
- First Cincinnati Open title after a heartbreaking runner-up finish in 2023
- Eighth Masters 1000 championship, extending his remarkable collection of big titles
- Third Masters 1000 crown of 2025, following victories in Monte Carlo and Rome
- 17-match winning streak at Masters 1000 level
- Sixth ATP title of the season, maintaining his position as the tour’s most successful player in 2025
At 22, he becomes the youngest champion in Cincinnati since Andy Murray in 2008, and the third Spaniard to lift the trophy after Carlos Moya (2002) and Rafael Nadal (2013).
The Sinner Situation
Jannik Sinner’s retirement raises immediate concerns about his fitness for the upcoming US Open, where he is the defending champion. The 24-year-old was on a 12-match winning streak and had won 26 straight matches on hard courts, bidding to become the first player to win back-to-back Cincinnati Open titles since Roger Federer in 2014 and ’15.
Sinner looked out of sorts from the outset under the mid-afternoon sun during an 88-degree day in Cincinnati, serving first and spotting Alcaraz a 40-0 lead in the opening game before Alcaraz took a 1-0 advantage. The world No. 1 struggled with his serve, recording two double faults and nine unforced errors to only four winners in the brief encounter.
Head-to-Head Implications
Monday’s result extended Alcaraz’s head-to-head record over Sinner to 9–5, including a 6–2 edge on hardcourts, with Alcaraz now holding a 9-5 advantage in his matchups with Sinner. This was their fourth meeting in a final this year, following encounters at the Rome Masters, French Open, and Wimbledon.
This year, Sinner won in four sets at Wimbledon, and Alcaraz won a five-set thriller at the French Open and in straight sets at the Rome Masters in May.
Rankings Battle Intensifies
The Cincinnati victory significantly impacts the year-end No. 1 battle between the two tennis superstars. Alcaraz has taken a firm grip on pole position in his battle for ATP Year-End No. 1 presented by PIF honours with rival Jannik Sinner, with the Spaniard entering the US Open with a 1,890-point advantage over Sinner.
As Sinner is defending champion at Flushing Meadows, Alcaraz will start with a 50-point lead in the PIF ATP Live Rankings once their points from the 2024 US Open are removed. This sets up a fascinating dynamic for the tournament that begins next week.
A Season of Dominance
Carlos Alcaraz’s 2025 season continues to be nothing short of spectacular. The 22-year-old has won an ATP Tour-leading six titles this season, including four Big Titles, with a tour-leading 54 wins and six titles in 2025. His collection now includes 13 “Big Titles” — a combination of Grand Slam championships, trophies at the Nitto ATP Finals and ATP Masters 1000 tournaments, and Olympic singles gold medals.
Alcaraz is 8-1 in Masters 1000 finals, with his only defeat coming in the 2023 Cincinnati final, in which he held championship point against Novak Djokovic before the Serbian rallied to victory in a thrilling final-set tie-break.
Looking Ahead to the US Open
With the US Open beginning next week, both players face different challenges. While Carlos Alcaraz heads to New York with tremendous confidence and momentum, questions linger about Jannik Sinner’s physical condition. Sinner is scheduled to participate in the US Open mixed doubles event tomorrow with Czechia’s Katerina Siniakova, but his participation must now be in some doubt.
The defending US Open champion will need to recover quickly if he hopes to defend his title and maintain his position at the top of the rankings. Meanwhile, Alcaraz, who won the US Open in 2022, arrives as a formidable challenger with the perfect preparation behind him.
