 Andy Murray of Great Britain hits a return against Marcel Granollers of Spain

Andy Murray marched into the third round of the US Open after overcoming Marcel Granollers AND a deafening air conditioning system, writes David McCarthy in New York.

Playing under the new £376million roof on the Arthur Ashe court, the noise level from the crowd and the air-cooling pipes made it almost impossible to hear the ball being hit and both players were complaining to the umpire.

That turned the match into one of the most bizarre contests of his career. But while it wasn’t a vintage performance from the Scot, he was never in danger of losing to a player he has beaten seven times in his career.

Murray did more than enough to win in straight sets 6-4 6-1 6-4, despite his serve not firing as effectively as it had done in the first round, and in the end his class told against a Spaniard who is rated No.40 in the world.

But what started off comfortably for Murray turned very strange, on and off the court near the end of the first set.

He even complained about the noise of the rain falling on the roof.

Granollers put up a stern test against the Scot

It’s tough. You couldn’t really hear the ball at all," Murray explained afterwards. "But we’re lucky that we get to play under the roof, so it’s good for everyone.

“I hit quite a lot of winners and although my first-serve percentage wasn’t great, I won a lot on my second serves.

"It was tough, having led 5-2 and had a bunch of set points, but thankfully I got through. It’s tough, and he’s a very tricky guy to play against."

Despite the din, the players managed to serve up an enthralling first set that Murray, who had been in control at 5-2 and had a set-point on Granollers’ serve in the eighth game, almost blew.

The Scot could not convert the chance and promptly lost that game and his own following serve, after missing a second set-point – the first time in the ­tournament he had been broken.

Suddenly, the Spaniard was back in the match at only 4-5 down.

Murray was furious with himself and what followed was the type of topsy-turvy game that has almost become the norm when Murray is in action.
