Djokovic complains to umpire about shot clock as crowd loudly boo before nearly throwing away first set at Australian Open

Novak Djokovic has sealed the first set of his tie against Tommy Paul in the semi-finals of the 2023 Australian Open 7-5 but was 5-1 up before a moment saw the 21-time Grand Slam champion capitulate.

Djokovic let the unforced errors in after complaining to the umpire about how long it takes to get towels and about the shot clock as a result. A similar complaint that Rafael Nadal has made.

This meant that the crowd showed their displeasure booing the Serbian which pre-tournament fans were warned about doing but until now he has received a good reception.

"The ball kids are not allowed to give me the towel," said Djokovic.

"Tell me how it works if it’s not working. It’s the first time that I’m going to get the towel this game. You start the clock before I touch the towel." And he threw in a snarky comment as he walked away, adding: "Well done."
