When you have the opportunity, you strike.

The roughest thing I ever said to an umpire was, 'Are you sure?'

There's a lot of ingredients go into being a good tennis player.

Roger Federer certainly is my claim to be the best of all time - if there is such a thing. With Rafael Nadal not far behind.

Manners are manners. Jimmy Connors and Ilie Nastase have no respect. I don't want my kid seeing Nastase play. The demeanor you show on the court is important to tennis.... Maybe we (yesterday's stars) were too stereotyped. But we were told to behave or they'd take our racket away.

I often surprise myself. You can't plan some shots that go in, not unless you're on marijuana, and the only grass I'm partial to is Wimbledon's.

An otherwise happily married couple may turn a mixed doubles game into a scene from Who's Afraid of Virginia Woolf.
