GENEVA — Novak Djokovic celebrated his 37th birthday on Wednesday by beating unseeded Yannick Hanfmann 6-3, 6-3 to reach the quarterfinals at the Geneva Open.

It was the 1,100th victory for the World No. 1 at ATP tournaments.

Djokovic rallied from 3-0 down in the final set by winning six straight games. He converted his second match point when Hanfmann's forehand hit the net.

The 32-year-old German broke Djokovic in the second game of the set when Djokovic struggled with his first serve.

The second-round match had earlier been suspended by rain with Djokovic trying to serve out the first set 5-3, deuce.

The record 24-time Grand Slam champion wasted a set point and had to save four break points before the match was interrupted by rainfall.

He had to save another break point after play resumed before serving out the set with an ace.
