Murray ousted; Serena surges

Disappointed. That was the word Andy Murray used over and over to describe how he felt about his exit from the U.S. Open. After all, Murray arrived at Flushing Meadows ranked No. 2, owner of a tour-leading 37 wins on hard courts this season — and quite sure he was prepared to win his first Grand Slam title a year after reaching the U.S. Open final. Instead, he heads home after the fourth round, a 7-5, 6-2, 6-2 loser to No. 16 Marin Cilic of Croatia on Tuesday.
