Andy Murray moves easily into US Open third round

NEW YORK — Cramp-free on a cool summer's night, Andy Murray moved easily into the third round of the US Open on Thursday with a 6-3, 6-3, 6-4 victory over Matthias Bachinger.

The eighth-seeded Murray, who battled cramps in his hamstring, shoulder and arm during a four-set win over Robin Haase in the heat of the day Monday, showed no such trouble on a crisp, 75-degree night in Arthur Ashe Stadium.

Murray, the 2012 US Open champion, has not reached a final since winning Wimbledon in 2013. He next faces Andrey Kuznetsov of Russia.
