Murray mounts Frenchman in four

Andy Murray is into the third round of the US Open after a hard-fought four-set win over Frenchman Michael Llodra.

The British number one had to dig deep to keep alive his Grand Slam hopes after an erratic 6-4 1-6 7-5 7-6 (9-7) win over the left hander.

Murray made a good start, but was outplayed in the second set before finally raising his game at a vital moment in the third to go 2-1 up.

But it took the Scot a tie-break to settle the match, saving two set points after the Frenchman twice went a break up in the fourth set.

Murray, the sixth seed, will play Austria's Jurgen Melzer in the last 32.

"(Llodra) is such a tricky guy to play against, he is very good at the net," said the 21-year-old Briton.

"It was a tricky match and I knew it was going to be tough but I am glad I came through. I think everyone feels a bit of pressure in those tense moments.

"I think he served well on those big points but he did miss an easy shot and I managed to get a few returns back."
