Murray repeated his Centre Court heroics over Gasquet when he came from two sets down to beat Melzer 6-7 4-6 7-6 6-1 6-3 at the Billie Jean King National Tennis Centre.

"They both were very good," Murray said. "I was in danger in both matches, but I felt like today Melzer was playing so well that it was going to be really tough for me to get back into the match."

He added: "Gasquet was obviously playing great too, but I still felt like I had a shot of getting back in there. And I had known in the past that he had struggled to close big matches out and struggled a bit over five sets.

"So that made it a little bit easier than today maybe."

The 21-year-old Scot said he had not been taken aback by the way Melzer, a left-handed serve and volleyer, had got off to such a strong start to their match or that he struggled to deal with it.

"The guy played great. It happens sometimes," Murray said.

"I'm not that good of a player that I can just blitz guys. But I said it was going to be a difficult match, and he's very talented.

"He's given top guys a lot of problems in the past. He's beaten (Andre) Agassi three or four times. He's a tough guy to play and he played great."
