Murray comfortably into round four

Andy Murray put the drama of the second round behind him at the US Open with a routine 6-1 6-4 6-2 victory over Feliciano Lopez to set up a fourth-round clash with rising American star Donald Young.

After coming back from two sets down to beat Robin Haase on Friday night, the world number four made a blistering start in front of the night session crowd on Arthur Ashe Stadium, winning the first set in 26 minutes without dropping a point on serve.

The second set was much closer but again it was Lopez that cracked first and there was no danger of a comeback from the Spaniard in the third.

Murray had beaten Lopez in all five of their previous meetings, including in the Wimbledon quarter-finals in June, and the left-hander's game is one that Murray particularly enjoys facing.

The 24-year-old had started slowly in both his first two matches but it was completely different on Sunday night as he reeled off 14 points in a row.

The crowd seemed to fear for the Spaniard and got behind him but Murray looked a totally different player to the one who had struggled so badly against Haase and he was displaying all his skills. Another break put him 5-1 ahead and he wasted no time in wrapping up the most comprehensive of sets.

Lopez needed to find something quickly just to stem the tide and a love game at the start of the second set was precisely what the doctor ordered. Not only did he win a point on Murray's first service game, he played a delightful lob and volley to create a break chance but then drilled a forehand long.

Murray looked a little frustrated that he could not re-establish his dominance of the first set but the break he craved was handed to him with a seventh Lopez double fault in the ninth game to leave the fourth seed serving for the set. And he had no trouble doing just that, clinching it with a delightful angled backhand.

The Scot's charge was briefly held up by a moth on court in the seventh game that evaded his grasp, but not much else did and a superb backhand overhead brought up his 11th break point of the match.

Lopez saved that one and the one that followed but the Spaniard put a backhand over the baseline on the third break point to leave Murray serving for the match. The Scot's first-serve percentage was a stellar 76% and he was not about to get broken now, sealing victory in an hour and 54 minutes.
