New British number one Andy Murray was soundly beaten in the first round of the Las Vegas Championship, going down in straight sets to Tommy Robredo.
Murray was broken at the start of the first set and never recovered, losing 6-2 6-2 to the third seed in under an hour in blustery conditions, reports BBC News Online.
The 18-year-old admitted the weather had played a part in his defeat.
“For the last couple of years I’ve not really played in anything as bad as what it was out there,” said Murray.
He added: “I could have played much better but I could have done with slightly calmer conditions after just coming from playing indoors for four weeks.
“It was not really great for getting into a rhythm and getting used to playing outside again – I even almost missed a couple of serves.
“But I also wasn’t quite all there unfortunately.”
