Murray, Federer move on

NEW YORK - Andy Murray was only briefly troubled by Nick Kyrgios in the most anticipated match of the U.S. Open's first round.

The third-seeded Murray, who won the title at Flushing Meadows in 2012, hit 18 aces and saved 11 of 14 break points en route to a 7-5, 6-3, 4-6, 6-1 victory over Kyrgios on Tuesday night.

Murray was mostly steady in the face of Kyrgios' various antics, which included appearing to take a nap during changeovers, smashing his racket and earning a warning from the chair umpire for cursing aloud.

Kyrgios has drawn a lot of unwanted attention lately, stemming from his trash-talking to Stan Wawrinka during a match in Montreal last month.

Second-seeded Roger Federer routed Leonardo Mayer of Argentina, 6-1, 6-2, 6-2, in a brisk 77 minutes. The 34th-ranked Mayer had given the 17-time Grand Slam champion trouble in their only previous meeting, when Federer saved five match points to win in three sets in Shanghai last year.

American Donald Young rallied from down two sets and a break to stun 11th-seeded Gilles Simon. The 68th-ranked Young won, 2-6, 4-6, 6-4, 6-4, 6-4, in 3 hours, 34 minutes with a packed Court 17 urging him on.

The 26-year-old Young's career has been one of extremes, a onetime teen prodigy who has stumbled through some long losing streaks as a pro. He reached his second ATP final in Delray Beach, Fla., in February, dropped nine straight tour-level matches from March through August, and then upset sixth-ranked Tomas Berdych in Montreal this month.

Young had never before come back to win after losing the first two sets.

Simon had been 5-0 against Young. The Frenchman lost in the opening round for the first time in nine appearances at Flushing Meadows.

One the women's side, Caroline Wozniacki needed just 67 minutes to win at the U.S. Open against an opponent making her Grand Slam debut. Those sorts of lopsided victories have been rare among the top women so far in the first round.

The fourth-seeded Wozniacki, last year's U.S. Open runner-up to Williams, beat NCAA champion Jamie Loeb, 6-2, 6-0. The 20-year-old Loeb earned a wild card into the draw by winning the college title as a sophomore at North Carolina.

Like Wozniacki, second-seeded Simona Halep had no trouble, moving on in 47 minutes on a hot, humid day when Marina Erakovic retired in the second set. Halep was leading 6-2, 3-0.

In a late match, fifth-seeded Petra Kvitova beat 126th-ranked Laura Siegemund, 6-1, 6-1.

Of the first 25 seeded players to take the court, nine lost. Half of the top 10 women are already out, counting third-seeded Maria Sharapova's withdrawal because of injury.
