Hampered Jannik Sinner loses from two sets and 5-1 up to Juan Manuel Cerundolo at Roland Garros

When Jannik Sinner led Juan Manuel Cerundolo 6-3, 6-2, 5-1 Thursday at Roland Garros, no one could have predicted the 180-degree turn to come on Court Philippe Chatrier.

With Sinner seemingly struggling with the excessive heat, Cerundolo stunned everyone inside by winning 18 of the final 20 games to bring the world No. 1’s 30-match win streak to a crashing halt in the second round.

The Italian had opened his event by playing in the night session against France’s Clement Tabur. This marks his earliest exit on the major stage since bowing out in the second round here three years ago to Daniel Altmaier.

Sinner had won every clay-court event he entered coming into Paris, picking up trophies in Monte Carlo, Madrid and Rome in cementing himself as the pre-tournament favorite. And with the absence of defending champion Carlos Alcaraz, it only strengthened Sinner’s bid to complete a Career Grand Slam.

Instead, Novak Djokovic is the lone former major champion left in the men’s draw—with Stan Wawrinka, Marin Cilic and Daniil Medvedev previously falling in the first round.
