Top-seeded Novak Djokovic advanced to the Rogers Cup semifinals, winning two matches Friday in the rain delayed tournament.

Djokovic, the defending champion in the hardcourt event, beat Sam Querrey 6-4, 6-4 in the afternoon in a third-round match that was originally scheduled for Thursday, then delayed by rain for 2 1/2 hours in the second set. The second-ranked Serb returned to the court at night to beat Tommy Haas 6-3, 3-6, 6-3 in a quarterfinal match that ended just before midnight.

Djokovic will face fellow Serb Janko Tipsarevic on Saturday. The fifth-seeded Tipsarevic beat No. 10 Marin Cilic 6-2, 6-4 in the third round, and topped 6-4, 6-4 in the quarterfinals.

In the other quarterfinals, eighth-seeded John Isner knocked out Canadian Milos Raonic 7-6 (9), 6-4; and 14th-seeded Richard Gasquet edged No. 11 Mardy Fish 5-7, 6-1, 6-2.
