A spot in the next round is at stake on Tuesday, when Raphael Collignon goes up against Rinky Hijikata in the Winston-Salem round of 32. Raphael Collignon limps in on a 4-match losing skid, just 4 wins in 10. Rinky Hijikata has won 4 of the last 10.

The serve is where this match separates: Collignon has been winning 72.6% of first-serve points to Hijikata's 68.8%, and on hard that gap compounds fast. The edge belongs to Collignon — real, but not the kind you take for granted at this level.
