Juan Manuel Cerúndolo produced one of the French Open’s most stunning upsets, rallying from two sets down to defeat Jannik Sinner 3-6, 2-6, 7-5, 6-1, 6-1 in the opening round. The Argentine converted 8 of 14 break points and fired 14 aces while Sinner unraveled with 64 unforced errors—nearly double Cerúndolo’s 33—to squander a commanding lead.
Sinner dominated the opening two sets, breaking serve at will and looking every bit the Roland Garros finalist from 2025. But Cerúndolo seized the pivotal third set 7-5, breaking the Italian’s rhythm and confidence. From there, the match became unrecognizable. Sinner’s second serve points won plummeted to just 41%, and he dropped 11 of the final 14 games as Cerúndolo—hitting 52 winners to Sinner’s 51—dictated play from the baseline with aggressive, high-risk tennis that left the favorite scrambling.
The fifth set was a formality. Cerúndolo claimed it 6-1, sealing the comeback and ending Sinner’s 10-match winning streak in one of the tour’s most improbable collapses. Sinner, who entered with a Rome Masters title and pristine clay form, simply had no answers once the momentum shifted.
Key Takeaways
- Cerúndolo fired 14 aces—triple his 4.7 clay-court average—while Sinner managed just 5, a clear sign the Argentine’s serve carried him through the final three sets.
- Sinner’s 64 unforced errors were catastrophic, nearly double Cerúndolo’s 33, and represented a collapse for a player who entered the tournament with a 10-0 recent record and elite clay form.
- The break point conversion disparity was decisive: Cerúndolo converted 57% (8 of 14) compared to Sinner’s woeful 31% (5 of 16), exposing the Italian’s inability to seize crucial moments once momentum shifted.
- Sinner won just 41% of second serve points, a disastrous return that left him vulnerable every time he missed his first ball—Cerúndolo exploited this ruthlessly, winning 55% on his own second serve to maintain control.
Player Analysis
Juan Manuel Cerúndolo
Cerúndolo entered this match with a 4-6 record over his last 10 matches and a pedestrian .475 win rate on clay. Nothing in his recent form—one clay win before the tournament, losses to Darderi in Madrid—suggested he could overcome a two-set deficit against a player of Sinner’s caliber. Yet he found something extraordinary in the third set. His 14 aces were a career-high performance, and his 52 winners showed he wasn’t content to grind—he took the ball early and attacked with controlled aggression. Most impressively, he kept his unforced error count at 33 while Sinner doubled that figure, a remarkable feat of composure under pressure. This is only his second career title, and it may be the biggest scalp of his career.
Jannik Sinner
This was a collapse of staggering proportions. Sinner arrived at Roland Garros having won 10 straight matches, fresh off a Rome Masters title where he dismantled Medvedev, Rublev, and Ruud. His clay credentials were impeccable: a .745 win rate on the surface, a French Open final appearance in 2025, and a recent stretch of dominant tennis. For two sets, he looked every bit the favorite, breaking Cerúndolo with ease and controlling rallies. Then the wheels came off. His 64 unforced errors—an astronomical figure for a player known for precision—and his 41% second serve points won betrayed a mental and tactical breakdown. He converted just 31% of break points, failing to capitalize on 11 opportunities. Whether the collapse was physical, mental, or tactical, it represents one of the most inexplicable losses of his career and raises serious questions about his ability to close matches when the pressure mounts.
