Jannik Sinner: An Embarrassing Stat for Alexander Zverev

There is one statistic that better illustrates Jannik Sinner’s dominance over Alexander Zverev than any other. In fact, the German has failed to break the world No. 1’s serve for 87 consecutive service games—an impressive statistic that highlights the Italian’s effectiveness on his serve and his steady improvement in recent head-to-head matches.

In an increasingly balanced game of tennis, being able to hold serve with such consistency against one of the best returners on the tour is an extraordinary feat. Zverev, a solid baseline player with an excellent return, found himself in a position to put pressure on Sinner on several occasions, but was unable to convert those opportunities into breaks.

This statistic takes on even greater significance when considering the caliber of the matches between the two, which are often played in the later stages of major tournaments. Sinner doesn’t just win the decisive rallies; he does so while maintaining an extremely high level of play on his own service games, alternating between powerful first serves, increasingly incisive second serves, and flawless handling of delicate points.

In recent months, the South Tyrolean’s serve has become one of the deadliest weapons on the tour. While just a few seasons ago it was an aspect of his game that still needed improvement, today it is one of the pillars upon which he builds his victories. His first-serve percentage, the effectiveness of his second serve, and his ability to find unreturnable shots under intense pressure allow him to face even the most dangerous opponents with confidence.

For Zverev, on the other hand, this long losing streak highlights all the difficulties he has faced against the Italian’s style of play. When Sinner serves with these percentages, the German struggles to enter the rally under ideal conditions and is often forced to play catch-up from the very first shot.
