Shuai Zhang vs Maria Timofeeva — R32 — Monterrey Open

Three holds from eight service games is what Shuai Zhang managed at the Monterrey Open, beaten by a qualifier who had not won a hard-court match all season. The betting market had made her a 53 percent pick, nearer a coin flip than the ranking gap implied; Maria Timofeeva broke in game 1 for 1-0 and again in game 5 for 4-1. Zhang broke back in game 5 for 2-3 and saved two match points, but she converted one of her six chances. The 66 minutes end a three-match losing streak for Timofeeva, whose previous win had come against Beatriz Haddad Maia at Wimbledon in June.
