"I was dead wrong at that," she said.

It's not a new sentiment for Carillo, who told me last year in an interview that the Williams sisters "created a Tiger-like buzz" when they started winning, but never made a Tiger Woods-like imprint on the game because "they play so seldom."

On Saturday, at a press briefing, Serena Williams responded to those comments in a typically aggressive way.

"Well, I think I've had a little more effect on tennis history than she has," she said. "I'm pretty excited about that."

Her endlessly quotable dad, Richard Williams, had this to say:

"I think that Mary has a good idea of tennis, but I'm just glad that the Williams sisters don't play the way she did so they have a chance of winning."
