Jannik Sinner's Dominant ATP Serve: The Numbers Tell the Story

After the 2025 US Open, Jannik Sinner set out to improve his serve to challenge Carlos Alcaraz.

Since then, he has taken the hardcourt season by storm and has made his serve one of his biggest strengths.

At the Miami Open, his performance was exceptional, setting new standards and demonstrating a remarkable evolution in his game.

During the Miami Open, Sinner finished the tournament with an impressive 68% first serve percentage.

This figure surpasses the best percentages of Roger Federer and Pete Sampras in Masters events.

Sampras achieved 64% in 1997, while Federer matched that mark in 2015.

Sinner won 94% of his service games, making him nearly unbeatable in best-of-three-set matches.

His dominance on serve was crucial in winning against Jiri Lehecka, especially in the closely contested first set.

He won 18 points in a row on his serve and closed the first set by winning 100% of points on his first serve.

In the first three months of 2026, Sinner has significantly increased the number of aces.

In 2025, he finished with 405 aces, ranking 19th among the season's biggest ace hitters.

Currently, he has already hit 232 aces, placing him in the top 10, above Felix Auger-Aliassime and Ben Shelton.

Sinner has already reached half the number of aces he achieved in all of 2025, demonstrating the magnitude of his progress.

Although he missed three months in 2025, he is expected to surpass his mark this season.

If Sinner maintains this power and precision in his serve, it could be an insurmountable challenge for his competitors on the ATP tour.
