Jannik Sinner, the top seed and a leading title contender at the French Open, was knocked out in the second round in a shocking upset against world No. 56 Juan Manuel Cerundolo of Argentina, 3-6, 2-6, 7-5, 6-1, 6-1.
The match was played under sweltering conditions with temperatures reaching 30°C. Sinner started strongly, taking the first set comfortably with a single break. In the second set, the Italian continued his impressive form, adding another break to claim it 6-2.
Sinner appeared in full control as he moved ahead 5-1 in the third set. However, at that moment, the 24-year-old began to struggle physically and called for a medical timeout while serving at 5-4. After a five-minute break, Sinner was immediately broken, allowing Cerundolo to level at 5-5 and eventually take the set 7-5.
Sinner's decline continued as he lost the fourth set 6-1 and was broken early in the fifth. Cerundolo seized every opportunity, winning the final set 6-1 to complete a remarkable comeback.
This is considered a major shock at Roland Garros, as Sinner arrived in Paris as the reigning champion of three major clay-court tournaments: Monte Carlo, Madrid, and Rome. Meanwhile, his main rival Carlos Alcaraz was absent due to injury, and Novak Djokovic had yet to rediscover his best form. With this loss, Sinner bids farewell to the French Open, leaving the tournament without its top seed.
