... Sharapova's screaming has turned a lot of people off. It's within the rules, but the rules, IMHO, need to be changed to prohibit this ugly form of gamesmanship. The rules on this could have been changed back in the early 1980's, but nobody made an effort. Now, it's been going on so long, it's like the players are responding, with a surly voice "What?"
And, as Tilden once said, "Pro tennis will succeed in spite of itself." And so, people keep buying tickets or watching on TV or internet, regardless of the loud screeching, howling, grunting, etc that happens on the court.
Sharapova seems to have a bit more "juice" [mph] on the ball than Woz has, so if we took out the screaming, I would rather see her play.
