Andy: I almost threw up.

Byline: David McCarthy 

ANDY MURRAY feared he was going to throw up on the Arthur Ashe court as he lost the second set to Paul Capdeville.

The Scot beat his Chilean opponent comfortably in four sets to reach the third round of the US Open but admitted he felt ill as he lost the second set 6-3. Murray recovered from the setback to lose only two more games in the rest of the match and said: "Basically, I played three good sets and one bad one.

"In the second set, I had a bit of a down physically. "I wasn't exhausted, maybe I didn't eat enough or I ate too close to the match because I felt like I was going to be sick.

"Perhaps that's the time change after playing my first-round match late in the evening but obviously I'll address that in the next round.

"After that, though, I backed off the baseline, went bigger on my first serve and got a lot more free points.I was happy with the way I played those final two sets."

Argentine Juan Martin del Potro, seeded to meet Murray in the quarter-finals next week for the second year in a row, beat Jurgen Melzer of Austria 7-6 (6) 6-3 6-3.
