How Sinner is close to doing what never has been done before
Jannik Sinner is closing on history.
The Italian might be on the back foot in the battle for ATP Year-End No. 1 presented by PIF honours. But according to an Infosys ATP Beyond The Numbers analysis, the World No. 2 has a chance to rewrite the record books in another way.
The 24-year-old currently leads the ATP Tour in both service games won and return games won. Since 1991, when the ATP began tracking such statistics, no player has topped both categories in the same season.
Service Games Won (entering Paris)
| Player | % Service Games Won |
| 1) Jannik Sinner | 91.45% |
| 2) Giovanni Mpetshi Perricard | 89.29% |
| 3) Taylor Fritz | 89.28% |
| 4) Reilly Opelka | 89.03% |
| 5) Novak Djokovic | 88.46% |
Entering the Rolex Paris Masters, Sinner has won 91.5 per cent of his service games for the season. No other player has held more than 89.3 per cent of their service games. Second on the list is Giovanni Mpetshi Perricard (89.3%), followed by Taylor Fritz (89.3%), Reilly Opelka (89%) and Novak Djokovic (88.5%).
Nobody else in the Top 5 of the service games won leaderboard also features in the Top 5 of the return games won chart. Sinner leads the way having won 32.7 per cent of his return games.
Return Games Won (entering Paris)
| Player | % Return Games Won |
| 1) Jannik Sinner | 32.68% |
| 2) Carlos Alcaraz | 32.55% |
| 3) Alex de Minaur | 30.14% |
| 4) Sebastian Baez | 28.72% |
| 5) Francisco Cerundolo | 28.68% |
Sinner’s great rival, World No. 1 Carlos Alcaraz, is just two-hundredths of a percentage behind in second place. Alex de Minaur is well behind in third (30.1%), followed by Sebastian Baez (28.7%) and Francisco Cerundolo (28.7%).
One year ago, Sinner became the first Italian to claim ATP Year-End No. 1 presented by PIF honours. In 2025, he has actually won a higher rate of service games won (91.5% to 91.4%) and return games won (32.7% to 28.3%) compared to 2024.
Sinner has taken a big step forward in his return game. Before this season, he had never broken more than 29.2 per cent of the time, which he did in 2023.
The performance has helped him remain in the hunt for year-end No. 1 with less than a month remaining in the season. Sinner’s hopes have increased after Alcaraz’s second-round loss in Paris.
Alcaraz entered Paris sixth in service games won (87.5%) and second in return games won (32.7%).
Sinner begins his Rolex Paris Masters on Wednesday against Zizou Bergs.
