Novak Djokovic upset by Alexei Popyrin in 3rd round of US Open - ESPN

NEW YORK — Novak Djokovic did not go easy on himself when assessing the listless way he performed from the start of the US Open, pointing to his sloppy serving as the main reason the defense of his 2023 title surprisingly ended in the third round.

«I have played some of the worst tennis I have ever played, honestly,» Djokovic said, just after midnight as Friday turned to Saturday. «Serving — by far — the worst ever.»

«It was just an awful match for me,» the No. 2-seeded Djokovic said. «I wasn't playing even close to my best. It's not good to be in that kind of state where you feel OK physically, and of course you're motivated because it's a Grand Slam, but you just are not able to find your game. That's it.

After all, Djokovic was trying to become the first player in tennis history with 25 Grand Slam singles titles. Instead, after knee surgery in June, he finishes a year without claiming at least one major championship for the first time since 2017. Before that, it hadn't happened since 2010.

Also of note: It's the first season since 2002 in which none of the
