Sinner makes ATP history with unmatched statistical double in 2025
Jannik Sinner may not have ended the year as the No. 1 player in the PIF ATP Rankings, but that did not stop him adding another significant achievement to an already successful season.
In 2025, the 24-year-old Italian became the first player in ATP history (since statistical records began in 1991) to lead the Tour in both percentage of service games won and percentage of return games won over the course of a single season. Sinner’s dominance in both areas helped him deliver a six-title haul, including a successful defence of his Nitto ATP Finals crown on home soil in Turin.
Across 64 matches in 2025, Sinner won 713 of 775 service games, according to Infosys ATP Stats, at a rock-solid 92 per cent hold rate.
Service Games Won (2025)
| Player | % Service Games Won |
| 1) Jannik Sinner | 92.00% |
| 2) Taylor Fritz | 89.18% |
| 3) Giovanni Mpetshi Perricard | 88.97% |
| 4) Novak Djokovic | 88.67% |
| 5) Reilly Opelka | 88.50% |
Sinner finished nearly three percentage points ahead of his nearest competitor Taylor Fritz and no other player held more than 89.18 per cent of his service games. The World No. 2’s margin over proven big servers — Fritz, Giovanni Mpetshi Perricard, Reilly Opelka, and even Novak Djokovic — underlines how far his serve has come and how central it has been to his rise.
“On the serve, we changed a lot of things after the US Open,” Simone Vagnozzi, one of Sinner’s coaches, said after the Nitto ATP Finals. “We are lucky to have Jannik [who] is really fast to improve, to understand the changes and everything… For sure our goal in the next season is to be more aggressive than what we are now.”
That strong platform fed directly into Sinner’s return game, winning 247 of the 757 return games he played (32.63 per cent) in 2025.
Return Games Won (2025)
| Player | % Return Games Won |
| 1) Jannik Sinner | 32.63% |
| 2) Carlos Alcaraz | 31.88% |
| 3) Alex de Minaur | 28.80% |
| 4) Francisco Cerundolo | 28.67% |
| 5) Sebastian Baez | 28.54% |
Sinner finished 0.75 percentage points ahead of his biggest rival, Carlos Alcaraz, with whom he split the four major titles in 2025. They also clashed in the Nitto ATP Finals title match, and Sinner used his effective return of serve to apply maximum pressure.
“The return of serve is incredibly important. If you don’t get the ball back in play, you’re not going to break serve too often,” Darren Cahill, one of Sinner’s coaches, said after the Nitto ATP Finals. “Jannik, even though he was down a break of serve in that second set, was consistently putting pressure on Carlos’ service games.”
The gap between Sinner and his closest peers reflects how consistently he applied pressure in return games — especially given that in 2024, the season in which he earned ATP Year-End No. 1 presented by PIF honours, he won 28.3 per cent of return games.
Rising from 28.30 per cent to 32.63 in just one year marks a significant leap. Combined with a serve that continues to grow in reliability and potency, Sinner now possesses one of the most complete statistical profiles in modern tennis, and a foundation that makes him a formidable threat heading into 2026.
