“All I can say… as I said many many times, you are truly a champion. I’m pretty sure from this situation you’re gonna come back better, even stronger. You always do. That’s what true champions do. You really are one. Sorry and come back stronger.”
Sinner’s apology to the crowd
Fighting through illness, Sinner explained his decision to retire.
Apologizing to the crowd, he said, “Usually I start with the opponent but today I have to start with you guys [the crowd]. I’m super super sorry to disappoint you. From yesterday I didn’t feel great. I thought I would improve during the night. It came up worse.”
He continued, “I tried to come out and make it at least a small match but I couldn’t handle more. I’m very very sorry for all of you. I know some of you on Monday maybe had to work or do something else, so I’m very very sorry.”
“Of course Carlos congrats. Another title. Not the way you wanted to win but it’s amazing what kind of season you’re producing. You and your whole team are doing amazing. Keep it up. I wish you only all the best for the U.S. Open and the rest of the season," Sinner added.
