France's Arthur Fils came out on top after a gruelling three-set encounter with Alexander Zverev to win the Hamburg Open on Sunday, defeating the hometown player 6-3, 3-6, 7-6 (7/1).

After victory in Lyon last year, it is the 20-year-old's second ATP title as he confirms his position as one of the sport's leading next-gen players.

World number 28 Fils overcame German top seed Zverev on the clay in Hamburg after just over three-and-a-half hours on court.

"I knew from the start it was not going to be easy. First set I was taking care of it, I think I had a little but of luck, but playing great. Then second set he managed to play better than me and to raise his level," said Fils during the trophy ceremony.

"When we closed the roof I knew it was going to be just a fight, like a dogfight. You just have to fight until the last point, until the last ball. I've practising for a long time for this kind of moment so I'm really happy to win it." (AFP)
