Great game vs Janko Tipsarevic

Great game!

Novak Djokovic secured his place in the semifinals by defeating his friend Janko Tipsarevic who retired in the fourth set with an injured leg 7-6(2), 6-7(3), 6-0, 3-0. After Tipsarevic retired from the 3 hour and 45 minute match, the two men shared a long friendly hug.

After battling through two arduous sets, with each winning in a tiebreaker, Djokovic won the third set 6-0 before Tipsarevic retired midway through the fourth. With Serbia playing in the semifinals of the Davis Cup the following week, he wanted to save himself rather than put more wear on his injured left hamstring.

"That's his decision," Djokovic said. "You know, I cannot comment on that. "I support anything he does because he's my friend and I know him well, and I know he's somebody who doesn't like to retire."

Now we're waiting for Roger Federer in semifinals, a rematch of last year's semifinals, an exhilarating five-setter which Novak Djokovic won.

Good luck Nole!!!
