A spot in the next round is at stake on Sunday, when Anastasia Potapova goes up against Sloane Stephens in the Cincinnati round of 64. Anastasia Potapova comes in at 6 wins from the last ten. Sloane Stephens has won 3 of the last 10.
The serve is where this match separates: Potapova has been winning 63.8% of first-serve points to Stephens's 60.8%, and on hard that gap compounds fast. The edge belongs to Potapova — real, but not the kind you take for granted at this level.
