Tearful Djokovic suffers US Open first-round exit

Novak Djokovic broke down in tears during a US Open first-round defeat by Argentina's Mariano Navone which provided further evidence age is fast catching up with the 39-year-old great

The 24-time Grand Slam champion was overcome by emotion in the deciding set of a dramatic match where he struggled physically throughout and had to vomit into a towel bin. Djokovic, seeded fourth, showed the fight for which he has always been renowned before succumbing to a 7-6 (7-5) 5-7 4-6 6-2 6-1 loss in a humid New York.

It was the first time the Serb had been beaten in the opening round at Flushing Meadows and the first time he had lost in the opening round of a Grand Slam tournament since 2006.

"I think it was obvious that it was an awful feeling on the court for me. I don't want to take too much out of Mariano's win. Congrats to him, he's a nice guy and a fighter - but I didn't enjoy myself," Djokovic said.

Djokovic managed to raise a smile as he congratulated 25-year-old Navone on what will rank as one of the biggest victories of the world number 49's career. But, after showing grace and class while congratulating his opponent, a disconsolate Djokovic was unable to keep a brave face for long and appeared close to tears again as he trudged back to the locker room.

The defeat ended Djokovic's latest bid for a standalone record 25th Grand Slam singles title, which would move him clear of Australia's Margaret Court. Chances are clearly running out for Djokovic. Many sensed this was another decent opportunity given world number one Jannik Sinner is missing through injury and defending champion Carlos Alcaraz is making his comeback from a long-term wrist injury.
