Match of the Day:  Garbiñe Muguruza (ESP) vs Alison Riske (USA)
Muguruza is one of the most vexing players to predict. She holds two major titles and was also a major runner-up. When she plays well, she looks like a star who could be setting the standard on the WTA Tour, but her style of play also seems to have a low margin for error. Riske is not exactly a backboard or defensive player. Still, she has a lot of momentum and confidence since Wimbledon. If Riske plays with self-belief, Muguruza will have to tap into a level I have not seen from her game in many months. My Prediction Alison Riske d. Garbine Muguruza 6-4, 6-3
