NEW YORK — The Latest on the US Open (all times local):
11:55 p.m.
Roger Federer shut out John Isner in a tiebreaker — something that had never happened to the big-serving, 6-foot-10 American in an official, tour-level match — and won their fourth-round U.S. Open match 7-6 (0), 7-6 (6), 7-5.
Federer broke in the last game, ending Isner's streak of 110 consecutive service holds at Flushing Meadows over the last two years.
Federer has not dropped a set on the way to a quarterfinal against No. 12 Richard Gasquet, who got past No.
