Andy Roddick

The U. S. Open champion Andy Roddick has given a revealing insight into the sort of behaviour the tennis umpire has to put up with. "I've never gone too far over the line," he told Rolling Stone magazine.

"There's a way to go about it. Like, if you're on a centre-court TV match and you go up and say point-blank, `... . you,' that probably wouldn't fly too well. You're probably going to get fined. So you'd say it more like under your breath and hope they hear it but don't really quite hear it, if you know what I'm saying.

"I've had some umpires come up to me and be like, `Man, on the court, you're the biggest ... to us, but off the court you always say hello. You're a totally different person. You're just weird, man."
