Jannik Sinner: The numbers speak for themselves—a surprising fact emerges from the comparison

While Jannik Sinner continues to train in Monte Carlo ahead of his scheduled return to the court in Beijing, a statistic that emerged after the U.S. Open reveals a striking difference when comparing his numbers to those of Alexander Zverev, the newly crowned champion in New York. The German, who claimed the second Grand Slam title of his career after weathering a particularly grueling stretch of weeks, is in fact the true “iron man” of the tour: in 2026, he has already played 66 matches spread across 15 tournaments, spending a total of over 152 hours on the court.

Sinner’s numbers, for various reasons, are quite different. The Italian, who has been sidelined since his Wimbledon final victory over Zverev due to knee tendonitis, has played 47 matches across 9 tournaments so far, logging just over 90 hours on court. After feeling unwell at Roland Garros, he took a deliberate break ahead of Wimbledon; following the tournament in England, however, he was forced to sit out due to a knee issue that has been treated in Turin over the past few weeks.

The comparison becomes even more telling when you broaden the view to include the entire new generation. Even Carlos Alcaraz, fresh off a long layoff due to a wrist injury, has in fact played just 30 matches this season. This situation raises questions about the need for different approaches to managing a schedule that is increasingly packed and demanding, regardless of the athlete’s age.

Zverev’s numbers are nonetheless surprising given the high volume of matches he has consistently played for years. In 2025, the German finished the year with 80 matches played, while in 2024 he reached as many as 88, confirming his status as one of the most active players on the tour. Sinner and Alcaraz, on the other hand, seem to be leaning toward a more selective schedule even in the near future: a choice that worries ATP executives, who by 2025 had become quite accustomed to seeing these two young phenoms face off in finals.

Now the world No. 1 is looking forward to his return. His schedule takes him to Beijing, a tournament where fans hope to finally see him back in action after more than two months away. In the meantime, however, the comparison with Zverev reveals a surprising fact: among the top players on the tour, no one has accumulated a workload comparable to that of the U.S. Open champion.
