Matches Played
Last year is history so now it's time to start fresh once again.  5 tournaments, and 5 undefeated players, plus Nicolas Kiefer and Janko Tipsarevic who withdrew after winning a match.  But one stands out: Thiago Alves, who qualified and won the title at the Sao Paulo challenger.  So he takes the early lead with 7 matches.

Winning Percentage
Same as above.
