Despite djokovic

Arthur Ashe Stadium: Defending champion Novak Djokovic suffered a shock defeat against Australia's Alexei Popyrin in the third round of the US Open on Friday (local time) and made his earliest exit at Flushing Meadows since 2006.

In three hours and 19 minutes long match, Popyrin stunned Djokovic 6-4, 6-4, 2-6, 6-4 while playing for the first time at Arthur Ashe Stadium in his career.

The Serbian, who was chasing his record-extending 25th major title and the 100th career title, will end the year without a Grand Slam win for the first time after 2017.
