Murray Wins Opener For Britain
Andy Murray registered a comfortable victory in Great Britain's opening Davis Cup rubber against the United States.
The Scot treated his home crowd in Glasgow to a dominant display against Donald Young to seal a 6-1 6-1 4-6, 6-2 victory in the opening match of the World Group first-round encounter in Glasgow.
Murray took just 46 minutes to wrap up the first two sets as the American floundered and kept his composure to regain control after Young stunned the home crowd by snatching the third set.
Murray set the tone for proceedings as he dropped just one point in the opening two games.
Young struggled to return the world number five's serves throughout the first two sets and hit the net on countless occasions during his own service games.
Murray sealed the first set with a forehand pass and the American did not even register a point during four consecutive games that spanned the first and second sets.
There were few more points for the American in the second set and some home fans chanted 'Can we play you every week?' at the Emirates Arena as Murray put Britain on course to follow up their 3-1 victory over the States at the same stage last year.
Young rediscovered some resilience at the start of the third set, hanging on to his serve during a series of rallies that were absent in the opening two.
The underdog continued to struggle on Murray's serve until the 10th game, when Young took the first two points to set up the chance for an extraordinary comeback.
Murray responded with an ace and then a volley to go level but two long forehands handed Young the set.
The world number 47 did not drop a point as he served the first game of the fourth set and looked a different player as he buzzed around the indoor court.
But Murray settled himself with a wonderful drop volley in the second game and then broke when Young sent a shot too long after a lengthy rally.
Murray further broke Young with the help of a brilliant backhand cross-court shot and an exquisite lob before serving out the match in confident fashion.
Speaking on court after the home win, the Dunblane-born player said: "It was pretty special and I'm glad I managed to play a good match and get the win.
"I played an extremely high level of tennis the first two sets. I was pretty fired up at the beginning, emotions were running high.
"I had a slight lull but I settled down and played a good fourth set.''
