Why didn't you include the sisters on that list? There isn't a single player that has a perfect game, everyone has chink and if they had no weaknesses, then the tour would be truly amazing. I am sure they all work hard, but people train differently. Unfortunately it takes more than hard work, it also takes alot of talent. I am sure if you talked to those who are always playing qualies, thier story would amaze you. They probably put in the longest hours, have tougher financial demands, can barely afford good coaches, fly all over the world for an opportunity and when they finally land in a main draw, they draw Serena and are back in the locker rooms in under an hour to start all over again. But then again, this is the story of all the players.
