ATP World No. 1 Jannik Sinner, the heavy favorite to win the French Open, is out of the tournament in the second round.
Sinner was defeated by Argentinian world No. 56 Juan Manuel Cerundolo in a five-set 6–3, 6–2, 5–7, 1–6, 1–6 match. The Italian had been up 5–1 in the third set, but started to struggle physically throughout the set. While up 5–4 and serving for the match, he called a medical timeout and was seen by a physiologist after initially receiving a time violation from the chair umpire.
During Sinner’s conversation with the umpire, he said that he felt dizzy and suggested that he was possibly dealing with dehydration. He also left the court prior to the fourth set.
