Murray wins opener against Young
Andy Murray handed Great Britain the ideal start to their Davis Cup clash against the United States with a straight-sets demolition of Donald Young in San Diego.
The Scot showed no ill-effects from his Australian Open exertions and had no apparent problems adapting to the newly-laid clay at Petco Park, home of the San Diego Padres baseball team, as he raced to a 6-1 6-2 6-3 win.
Young, the world number 79 who replaced the injured John Isner in the US team, had no answer to Murray's game as the Wimbledon champion wrapped up victory in the first rubber of this World Group quarter-final.
Murray went into the match on the back of a run to the quarter-finals in Melbourne and still feeling his way back into the rigours of the main tour after back surgery.
But he needed no time to find his feet on Friday as he broke twice in each set to finish the match in one hour 38 minutes.
He was dominant on serve, not even facing a break point in the first two sets and saving the two he did in the third, and laid brutally into Young's second serve.
"It's important to get off to a good start," Murray said on BBC3.
Murray said the court had played slower than during practice over the past days because of the damper conditions, but added: "It's still pretty slippy, it's tough to change direction."
American Sam Querrey will go in as favourite against James Ward in the second singles rubber.
This is Britain's first World Group quarter-final since 1986 and their last victory over the US in the competition came way back in 1935.
