Serera Williams demolishes Maria Sharapova 6-0, 6-1

Serena won the first eight points of the match and the rout was on.

What you may have missed on TV is that Serena left the court right as the match was suppose to start.  If it was a bathroom, it would have been very odd since the players were on the court no more than 10 minutes before Serena disappeared.  Sharapova jogged in place and hit a couple of practice serves during the delay.  When Serena reemerged onto the court, the chair umpired announced, "Time."  Instead of walking onto the court, Serena sat down, and took a slow, deliberate drink of water and the crowed booed.  I don't think any of this behavior was accidental.  It's my guess that Serena was trying to get Sharapova off her game.  It worked.

Sharapova won only one game and had only two break points the entire match.  She was struggling just to win points, let alone games.
