Andy Murray sent an early signal that he is ready to make a serious run at the US Open title when he made it through to the second round with ominous ease, by beating Lukas Rosol 6-3 6-2 6-2 in what was his first match in the Arthur Ashe Stadium since its new roof was fully installed.
Back under the watchful eye of Ivan Lendl for the first time since winning Wimbledon, the 29 year-old Scot was on the late night shift for his match against another Czech, Lukas Rosol.
After a few close early games there were no indications of any fatigue from his exertions at the Olympics and Cincinnati Masters.
Faced with a sometimes explosive opponent who had pledged that he would take risks, Murray soaked up what he needed to and protected his own serve to the extent that he did not face any break points.
He will now face world No 45 Marcel Granollers of Spain, having made it three British men in the US Open second round for the first time since 1978, joining Kyle Edmund and Dan Evans.
