Serena Williams' yells of "Come on!" were crescendoing right along with the tension in a fourth-round U.S. Open match that began as a rout and suddenly became riveting.
When she ripped a backhand winner to claim the third set's opening game Sunday, Williams let out her loudest shout of the day, leaning forward and rocking both arms. This turned into a test, and she passed it.
Williams reached the quarterfinals at Flushing Meadows for a 10th consecutive appearance — she wasn't there last year because she gave birth to her daughter during the tournament — by picking her level up after a lull and using 18 aces to beat Kaia Kanepi of Estonia 6-0, 4-6, 6-3.
