Back in Basel for the first time in 15 years, the 39-year-old Djokovic fell 6-7(4) ,7-5 7-6(5) , in the second round on Thursday, his first defeat by German veteran Struff in nine meetings.

"I knew I needed to go for it. There was only one way to play it. So I was very happy," said Struff, who clinched the win with his 27th ace of the match.
