Flushing Meadows, NY (SportsNetwork.com) - Novak Djokovic eased into the fourth round at the U.S. Open on Saturday with a straight-set pounding of American Sam Querrey.

Djokovic, the 2011 champion at Flushing Meadows, needed a mere 85 minutes in a 6-3, 6-2, 6-2 rout at Ashe Stadium. The reigning Wimbledon champ has not lost more than four games in a set through his first three matches as he continues his quest toward a fifth straight appearance in the title match at the USTA National Tennis Center.

The top-seeded Serb has lost in the final each of the last two years and also fell in the 2010 title match. He'll next take on the winner between American John Isner and Germany's Philipp Kohlschreiber.

Other early winners Saturday were fifth-seeded Milos Raonic and 10th-seeded Kei Nishikori.

Raonic, a semifinalist at Wimbledon earlier this summer, advanced to the fourth round in New York for the third straight year thanks to a 7-6 (7-5), 7-6 (7-5), 7-6 (7-3) win over Victor Estrella Burgos of the Dominican Republic. The Canadian has yet to advance past the round of 16 however, and will try to do so against Nishikori, who thumped Argentina's Leonardo Mayer, 6-4, 6-2, 6-3, on Saturday.

Also scheduled for later will be Australian Open champion Stan Wawrinka. The third seed from Switzerland will take on Slovenia's Blaz Kavcic.
