Jannik Sinner, the world No. 1 and top seed at Roland Garros, surrendered a commanding position Thursday after a sudden drop in level and a medical stoppage against Juan Manuel Cerundolo.
Sinner had run up a score of 6-3, 6-2 and was leading 5-1 when his play faltered; he lost three consecutive games to fall to 5-4 and then found himself on the brink of losing a fourth at 40-0 before leaving the court for treatment.
Television images and on-court behaviour showed Sinner appearing to be bothered by his left hip; he also rubbed his thighs after departing the court. The break lasted about ten minutes before the world No. 1 returned to the court.
The minutes away did not restore the earlier rhythm. Cerundolo, ranked 56th in the world, capitalized and won the third set 7-5. A fourth set began after Cerundolo's comeback set victory, turning what had looked like a routine second-round passage at roland garros into a competitive match.
The raw numbers underline the swing: a player who had dominated two sets at 6-3 and 6-2 suddenly faced a 5-4 position after losing three games in a row, with a near-break against him at 40-0. Those figures are the clearest measure of how abruptly the match pivoted.
For Sinner, the disruption came at a moment when he had been on course for a straightforward qualification for the third round of the tournament. The match was part of the second round at Roland-Garros, and the immediate significance is how a leading contender’s rhythm can be overturned by a short sequence of games and a medical stoppage.
Cerundolo’s run to take the third set 7-5 reinforced the point that a momentum shift of a few games can be decisive on the clay in a best-of-five format. Ranked 56th, he erased a 5-1 deficit in the third set to steal it at the end, seizing the opening Sinner had relinquished.
The tension in the match is straightforward: Sinner’s authority in the first two sets and his visible physical complaint do not sit together neatly. A player at No. 1 losing ground in one swing and then needing treatment creates a clear gap between the expectations set by the early scoreline and the reality on court.
That gap raises immediate, practical questions for the rest of the day at Roland Garros. If the left hip issue that appeared to bother Sinner after he rubbed his thighs is genuine, it changes the match dynamics; if it was a temporary cramp or discomfort eased by treatment, Sinner may yet reassert control. The facts on the scoreboard so far — 6-3, 6-2, 5-1 turned into a 7-5 third set for Cerundolo — have already altered the match’s narrative.
What happens next matters beyond this single match. A continuation of Cerundolo’s surge would force the world No. 1 into extended work on clay and could complicate his path through the draw. Conversely, a resurgent Sinner would reset expectations and underline why he is the top seed.
The single, most consequential unanswered question after Thursday’s play is this: can Sinner shake off whatever disrupted him at 5-1 and reclaim the command he held for the opening two sets, or will Cerundolo complete the comeback that the third set began?
