Jannik Sinner<\/a> has been near-perfect in 2026, but there is one glaring worry for the World No 1 across the season.<\/p>\n

The Italian completely capitulated in the second round of Roland Garros and it cost him his very first Grand Slam at the Paris tournament.<\/p>\n

Sinner was two sets and a break up against Juan Manuel Cerundolo when he completely lost his way, from what looked like a combination of heat exhaustion and fatigue issues.<\/p>\n

The World No 1 had played a lot of tennis on the European clay court swing, winning Monte Carlo, Madrid, and Rome back-to-back, but it was still a major concern for Sinner.<\/p>\n

He bounced back beautifully at Wimbledon to win the title for a second consecutive year, which makes his issues at Roland Garros even stranger.<\/p>\n

His coach, Simone Vagnozzi<\/a>, has finally revealed his thoughts on the matter in a new interview with Corriere della Sera<\/a>.<\/p>\n

Asked what the issues behind Sinner\u2019s<\/a> capitulation were, Vagnozzi responded: \u201cI don\u2019t think there\u2019s a single cause; many small things, when combined, can lead to these small slumps, but let\u2019s remember that there have been four in the last five years.<\/p>\n

\u201cThese guys aren\u2019t robots. Heat, fatigue, and tension can all combine. The temperature in Paris was prohibitive, and he arrived there under significant physical and mental stress.<\/p>\n

\u201cIn short, there\u2019s no single factor; in that case, it would be easier for us to correct it. We have to live with these episodes, working to avoid them. There can be a strong, stupid player. But there can never be a stupid champion.\u201d<\/p>\n

Sinner might have bounced back from his early Roland Garros<\/a> exit, but it is still clearly lingering in his mind.<\/p>\n

The star has opted not to play the Canadian Open to begin his North American swing, despite the fact he has played little tennis over the summer.<\/p>\n

The star\u2019s appearance at Wimbledon<\/a> was his only competitive tennis action since the 28th May, when he was dispatched by Cerundolo<\/a> at the French Open<\/a>.<\/p>\n

That means Sinner has played just seven matches in two months, so he is surely fresh enough to compete at the Canadian Open.<\/p>\n

The star is clearly being selective with the tournaments he plays after his gruelling time on the clay court swing.<\/p>\n

If Sinner is able to win the US Open<\/a> for the first time since 2024, his decision will surely be the right one.<\/p>\n

Sinner\u2019s next tournament is now expected to be the Cincinnati Open, which is set to begin on August 13th. The Italian reached the final of the tournament in 2025.<\/p>\n
