Here's what Jannik Sinner said about his early withdrawal.

Speaking after Monday's disappointing showing, he said: “Didn’t feel great from yesterday. Also during the night, I thought I would recover a bit better, but it was not the case. And I just tried to go out for the fans, trying to give a match.

“That’s the reason why I went on the court, but it was not meant to be for me today. So, you know, it happens. And, but another way, I don’t want to take anything away from Carlos. He had a great week, great, great tournament again. And now the main focus, obviously, is for the US Open. And yeah, now recovery is the most important. And then we see.”
