A spot in the next round is at stake on Wednesday, when Anastasia Potapova goes up against Nikola Bartunkova in the Monterrey round of 16. Nikola Bartunkova comes in at 6 wins from the last ten. Anastasia Potapova limps in on a 2-match losing skid, just 5 wins in 10.
Bartunkova's 67.9% behind the first serve (against 63.8% for Potapova) means break chances should be scarce in one direction. Little separates them; Bartunkova gets the nod on the finest of margins.
