Murray out, Federer advances at US Open

Andy Murray was sent packing at the fourth round of the US Open, his earliest Grand Slam exit in five years, while 17-time major winner Roger Federer of Switzerland reached the quarterfinals on Monday.

South African 15th seed Kevin Anderson upset British third seed Murray 7-6 (7/5), 6-3, 6-7 (2/7), 7-6 (7/0) to end his run of 18 consecutive major quarterfinals since the 2010 US Open.

"That's something that is disappointing to lose because of that. That's many years' work that's gone into building that sort of consistency. To lose that is tough," said Murray.

"Also to lose a match like that, that was over four hours, tough after a couple of tough matches earlier in the tournament as well, it's a hard one to lose."

Anderson reached his first Grand Slam quarterfinal after seven prior fourth-round defeats.

"It was the match of my life," Anderson said. "This is a great accomplishment for me."

Anderson will be facing Swiss fifth seed Stan Wawrinka.

Reigning French Open champion Wawrinka defeated US left-hander Donald Young 6-4, 1-6, 6-3, 6-4 in the fourth round.

The Swiss dropped his first set of the tournament but reached an eighth quarterfinal in his past nine Grand Slams.

Swiss second seed Federer, seeking his sixth US Open title, dispatched US 13th seed John Isner 7-6 (7/0), 7-6 (8/6), 7-5 to reach a quarterfinal against French 12th seed Richard Gasquet, who defeated Czech sixth seed Tomas Berdych 2-6, 6-3, 6-4, 6-1.

Federer now is trying to become at 34 the oldest US Open champion since Ken Rosewall in 1970. Endi
