French Open stunner: No. 1 Jannik Sinner struggles with dizziness during heat wave in 2nd-round loss

PARIS (AP) — Not since Rafael Nadal was winning his record 14 French Opens had a player come to Roland Garros as such an overwhelming favorite to win the clay-court Grand Slam. Jannik Sinner had won everything there was to win in tennis over the past three months: five straight Masters 1000 titles — three of them on clay — and 30 straight matches. And with Carlos Alcaraz, his biggest rival, out due to an injured right wrist, it seemed almost a foregone conclusion that Sinner would raise the Coupe des Mousquetaires trophy and complete a career Grand Slam. That's why Sinner's meltdown amid the Paris heat wave was so stunning Thursday. The top-ranked Sinner struggled with dizziness and was beaten by 56th-ranked Juan Manuel Cerundolo 3-6, 2-6, 7-5, 6-1, 6-1 in the second round after wasting a chance to serve for the match. "I didn't feel very well on court," Sinner said. "I struggled, starting to feel very dizzy, very low on energy." Sinner said that when he woke up on Thursday he "didn't feel very well." Sinner bent over on the clay court in apparent exhaustion multiple times and was hardly even running for shots as the match wore on, resorting to drop shots and serve-and-volley tactics to try and shorten the points. He attempted to cool himself with a hand-held fan on changeovers and put bags of ice around his neck. The temperature at the start of the match was 29 degrees C (84 F) and rose to 32 C (90 F). "It was warm but not crazy warm," Sinner said. "I feel like it was quite OK to play. Really it was nothing against the heat, nothing against the weather. It was just me today, but it happens." Cerundolo didn't celebrate too much when it was over, just producing a little wave to the crowd. "It's tough for him," Cerundolo said. "I couldn't win more than three games by set. So I think I was a little bit lucky. … He was deserving to win in this match. But then I don't know what happened. … I feel sorry for him and hope he recovers." Sinner led by two sets and 5-1. When he served for the match a second time at 5-4, he bent over at 0-40 and then walked to his chair. He asked for assistance and left the court. His entire light blue outfit was soaked through with sweat. After losing the set 7-5, Sinner received medical attention and left the court. Minerals were added to his drink when he returned but Sinner wasn't able to recuperate. Sinner's previous loss came Feb. 19 in the Qatar Open quarterfinals. He had won five straight Masters titles while dropping just three sets. "We'll definitely do some tests to be sure of what happened today," he said. "Let's hope we're ready for Wimbledon," Sinner added. "To be ready there, we need to recuperate well and do things right now." But Sinner has a history of struggling in the heat. He admitted he was lucky at the Australian Open in January against Eliot Spizzirri when the roof was closed and the third-round match swung his way. And he had to retire from a match in Shanghai in October that was contested amid extreme humidity. "Shanghai was very tough. Humidity very high. Australia was very, very warm," Sinner said. "Here, I mean it was warm, but it was OK. It was not like I was dying because of the heat. I think today was completely different scenario. "It's tough to accept, of course, because of the position where I've been in and everything considered," added Sinner, who sportsbooks had listed at around -300 to win the tournament. On the same Court Philippe Chatrier last year, Sinner wasted three match points against Alcaraz and lost an epic final. 17-year-old advancesIn other matches, 17-year-old Frenchman Moise Kouame became the youngest man to reach the third round of a Grand Slam since Rafael Nadal was also 17 at 2003 Wimbledon. Kouame beat Adolfo Daniel Vallejo 6-3, 7-5, 3-6, 2-6, 7-6 (8). And Cerundolo's older brother, Francisco, beat Hugo Gaston 2-6, 6-4, 6-2, 6-1. In women's action, Naomi Osaka put on another fashion show for her walk-on before beating Donna Vekic 7-6 (1), 6-4.
