Matches Played
Things at the top get a little tighter as Benjamin Becker got in 4 matches.  But after 4 weeks of inactivity, Juan Albert Viloca returned to action and got in a couple of matches to stay on top.  But his lead is now just 1 match.  Pablo Santos-Gonzalez moved into 3rd.

Winning Percentage
US Open results are through the third round so Roger Federer is not quite caught up to Jo-Wilfried Tsonga.  After winning Germany F14, Thomas Schiessling appears on the list in 3rd with a 14-1 record.
