Novak Djokovic sailed into the U.S. Open third round Wednesday in his quest for a 24th Grand Slam triumph as Iga Swiatek and Coco Gauff stayed on a quarterfinal collision course in New York.

Djokovic climbed through the gears against 76th-ranked Bernabe Zapata Miralles, winning 13 of the last 15 games to ease through 6-4, 6-1, 6-1 on Arthur Ashe Stadium court.

"At 36 years of age, after 20 years of coming to New York, I still have the hunger to play my best tennis on this court," said Djokovic, a three-time U.S. Open champion.
