Capitals 2007 MVP Mark Knowles recorded his 600th career doubles win in tandem with long-time partner Daniel Nestor at the U.S. Open on August 31. 

The former champions and No. 2 seeds overcame Yves Allegro and Kristof Vliegen 6-7(4), 6-4, 6-1 for a place in the third round. The duo won the 2004 title (d. Paes-Rikl) and finished runner-up in 1998 (l. to Stolle-Suk). They are playing together in New York for the 10th time.

Bahamian Knowles, who turned professional in 1992, has a 600-286 career record, while Canadian Nestor is now
