NEW YORK (AP) - Aside from a brief first-set blip, Roger Federer was rather dominant in a 6-4, 6-3, 6-2 victory over 17th-seeded Roberto Bautista Agut of Spain that put the five-time champion in the U.S. Open quarterfinals for the 10th time in 11 years.
Federer was broken only once, part of a three-game run for Bautista Agut that took the score from 5-1 to 5-4. But Federer had no trouble the second time he tried to serve out that set, which he ended with a pair of aces.
Moving well and winning the point on 35 of 52 trips to the net, the second-seeded Federer needed less than two hours to improve to 25-1 in night matches at Arthur Ashe Stadium.
A year ago, Federer lost in the fourth round at Flushing Meadows.
