Wozniacki wins over Serena:

So now she plays Sharapova, who blasted past Li Na, 6-3, 6-0.  This'll be a pretty match.

Meanwhile, there's the ups-and-downs of trying-to-get-fit Andy Roddick:

Andy Roddick upsets Roger Federer at Key Biscayne
 
NOBODY beats Andy Roddick 22 times in 24 matches!  (His Wimbledon 2009 is still one of the greatest runner-up efforts in the history of the tournament.  Not a single loss of serve until the final game.  Geez.) 

Of course, he lost in the next round.  Obviously Djokovic is odds-on favorite for tourney title.  But Nadal is here too.
