(CNN) -- Top seeds Andy Roddick and Novak Djokovic cruised to straight sets second round wins at Flushing Meadows on Thursday to advance their bid for the U.S. Open title.
Roddick, the 2003 tournament winner and fifth seed, dispatched Marc Gicquel of France 6-1 6-4 6-4, nailing 13 aces and making just 10 unforced errors to the Frenchman's 37.
Earlier, the fourth-ranked Serbian Djokovic cast aside Carsten Ball of Australia, 6-3 6-4 6-4, making just 18 unforced errors to Ball's 45 -- though Ball knocked off nine aces.
Djokovic's best finish at the tournament was in 2007, when he lost to Roger Federer in the final.
Other top seeds Federer and Rafael Nadal have advanced to the third round, as well as 21st seed American James Blake
