Oleksandra Oliynykova vs Diane Parry — R16 — Monterrey Open

Ranked 20 places higher, Oliynykova converted all five break points she earned and lost anyway. The market never had her: 10Bet made the 66th-ranked Parry a 70 percent favorite. Parry drew twelve break chances to her opponent's five and took six, in a match where the two of them held 11 of 22 service games between them. She broke in game 8 for 5-3, then handed serve straight back, Oliynykova erasing two match points to break for 4-5, and closed it in the breaker instead. That is 1 hour 56 minutes with almost no serve to speak of, and Parry, 8-4 on hard courts this season, is into the quarterfinals after coming through Vekic in the previous round.
