Jannik Sinner’s 2026 season has been a masterclass in tennis dominance. The Italian became the youngest player in the Open Era to complete the career Golden Masters by capturing all nine active Masters 1000 titles. Along the way, he completed a flawless straight-set Sunshine Double and secured his fifth Grand Slam title at Wimbledon.
But beneath the success lies the punishing reality of the hectic 11-month ATP Tour calendar. Even for a 24-year-old world-class athlete like Sinner, the grind is exhausting. So, should he play every Masters 1000 event? French tennis coach Patrick Mouratoglou recently weighed in on that question.
Patrick Mouratoglou Warns Jannik Sinner’s Relentless Masters 1000 Schedule Could Cost Him at US Open
On a reel posted on his Instagram account, Mouratouglou expressed disbelief at how Sinner is managing his workload amid his winning spree. “I don’t know how he can win back-to-back Indian Wells, Miami, and then again play almost immediately after Monte Carlo and then Madrid and then Rome and then Roland Garros. I thought, I mean, who can do that? It’s crazy,” Mouratoglou said.

The veteran coach acknowledged that Sinner might be built differently than his peers, but he also warned that the grind could eventually catch up to him. “Physical is one thing, but emotional is important too. You need to be fresh emotionally. And this is always a balance that is very difficult to find,” Mouratoglou added.
There have been warning signs of exhaustion in Sinner’s matches this year. At the French Open, after leading 6-3, 6-2, 5-1 against Juan Manuel Cerúndolo, Sinner had a physical collapse in the Paris heat, feeling dizzy and nauseous, eventually losing in five sets (3-6, 2-6, 7-5, 6-1, 6-1). Earlier, during the Madrid Open in early May, he had admitted feeling fatigued due to the schedule.
Last year, Sinner had missed the Canadian Open due to an elbow injury and the need to recover after winning Wimbledon.
Following a grueling stretch that tested his stamina, his coaching camp must be carefully evaluating his upcoming schedule. When asked if the Italian will be playing the Canadian Open and the Cincinnati Open back-to-back following his Wimbledon win, his coach Simone Vagnozzi said, “For sure, Masters 1000 is really important tournament after the Slams. So we are going to speak tonight, probably tomorrow, and we see how we plan the schedule.”
Sinner is on the entry list of the National Bank Open in Montreal, a.k.a. the Canadian Masters, and he will be looking to match the record for the most Masters 1000 titles in a single season, with six, at the sixth Masters 1000 event of the year.
