Andy Murray is through to the third round of the US Open after beating Paul Capdeville.
The world number two recovered from losing the second set to Capdeville, responding with some of his best tennis so far this tournament.
Murray then went on to win but reckons he wasn't on his best form because he didn't eat well before the match.
He said: "I wasn't exhausted, maybe I didn't eat enough or I ate too soon to the match."
"Basically, I played three good sets and one bad one."
Murray will take on American wildcard Taylor Dent in his next match.
