World No. 1 Jannik Sinner was eliminated from Roland-Garros in the second round by unseeded Argentine Juan Manuel Cerúndolo, 3-6, 2-6, 7-5, 6-1, 6-1, according to CBS Sports. The loss ended Sinner's 30-match winning streak and removed the overwhelming tournament favourite from contention for the only Grand Slam missing from his collection.

How did the upset unfold?

Sinner dominated the opening two sets and led 5-1 in the third set while serving for the match, but physical deterioration in the Paris heat allowed Cerúndolo to mount an improbable comeback. Temperatures reached 33 degrees Celsius during the match, and Sinner's movement visibly slowed as the contest progressed. After requesting a medical timeout for dehydration-related concerns while serving for victory, Sinner was granted a break from the court. From that point forward, Cerúndolo won 15 consecutive points to force a fourth set and eventually claimed the final two sets without further resistance, according to CBS Sports.

Why the medical timeout proved controversial

Commentator Jim Courier criticised the umpire's decision to grant Sinner a medical timeout, noting that players are typically not permitted such breaks for cramping or heat-related issues. Courier stated on the TNT broadcast that the rules were being bent for top players, a concern that echoes similar criticism Sinner faced earlier in 2026 when Daniil Medvedev objected to a timeout during their Italian Open match, according to CBS Sports.

What this means for the tournament

Cerúndolo, ranked outside the top 50, advanced to the third round of a Grand Slam for the first time in his career. The 24-year-old's victory opens the field for other contenders, including Novak Djokovic, who is pursuing his record-extending 25th Grand Slam title. Sinner's exit marks his first loss on tour since February.
