I never faced Pete (Sampras) in a match. I think from watching, his is the best serve ever. And he is the only guy that I would probably not take the bet that he would so often offer in practice -- he's down love-40, says '10 bucks, I still hold serve.' I probably wouldn't even take that against him. So many times he would come back and win. He would just put it on the dime. I also wouldn't take the bets when we were just practicing our serves, he put just a tennis ball can on the other side, and says, 'A hundred bucks for who hits more.' That's not a safe bet with him.
