Novak Djokovic reached his 17th straight Grand Slam quarterfinals by beating German veteran Tommy Haas 6-1, 6-4, 7-6 (4) at Wimbledon on Monday.

Djokovic trailed 4-2 in the second set but won the next four games.

He failed to serve out the match at 5-3 in the third and wasted a match point in the next game before closing out the tiebreaker with a forehand winner on his fourth match point. He has yet to drop a set this tournament.

Djokovic now faces No 7 Tomas Berdych, who reached his first Wimbledon quarterfinal since he was the runner-up in 2010 by beating Bernard Tomic 7-6 (4), 6-7 (5), 6-4, 6-4.

Djokovic's quarterfinal streak is the third longest all time behind Roger Federer's 36 and Jimmy Connors' 27 straight last-eight appearances. Federer's streak ended when he was upset in the second round last week.
