Tommy Haas beat world number four Novak Djokovic 6-3 6-7 (4-7) 6-1 to win his national tournament, the ATP Halle Gerry Weber Open.

It was the German Haas' first victory in his career over the Serbian Djokovic, who was ranked number one for the competition, following Federer's withdrawal.

Haas upset Djokovic by racing through the first set, but double-faulted in the tie-break to lose the second set. When it came to the crucial third set Haas broke Djokovic twice to win the decider with ease.

"I never believed that I would end the week with the title," said Haas.

"It is unbelievable. I would like to thank the public for their great support, it has really been a wonderful week for me." Haas added.

Djokovic who didn't appear too upset by the defeat conceded that his opponent Haas had played the better tennis.

"Tommy completely deserved the win," Djokovic admitted.

"Getting to the final is a good achievement," Djkovic added. "I had enough matches on grass before Wimbledon but I would not call myself one of the favourites."
