Jannik Sinner is widely regarded as one of the most complete players on the ATP Tour right now, but a curious statistical quirk reveals a genuine area where the world No. 1 still has room to grow. Over the past year, Sinner has landed just 63.8 percent of his first serves, placing him 35th on tour in that category. Alexander Zverev leads the stat with an eye-catching 72.5 percent, followed by Sebastian Baez at 72.1 percent and Giovanni Mpetshi Perricard at 70.6 percent. Even Carlos Alcaraz and Novak Djokovic rank above Sinner, sitting 14th and 10th respectively.
The flip side of that number, however, is remarkable. When Sinner does land his first serve, he is almost unplayable. He tops the entire tour in percentage of service points won at 80.9 percent, edging out Reilly Opelka at 80.8 percent and Taylor Fritz at 79.7 percent. He also leads the field in service games held, converting an astonishing 92.9 percent of them. The power and precision once the ball is in play clearly compensates for the consistency gap on the delivery itself.
Sinner has been aware of this dimension for some time. After losing the 2024 US Open final to Alcaraz, he openly committed to making adjustments, describing small tweaks that could bring greater unpredictability to his game. His retained Wimbledon title this month suggests significant progress, though the first-serve percentage numbers indicate the work is ongoing.
For a player already dominating the tour, closing that consistency gap could make him even more difficult to break down. TennisDraw users backing Sinner deep into major draws might feel even more confident if that serving percentage climbs closer to the top of the rankings.
