MASON, Ohio — Garbine Muguruza reached her first Western & Southern Open final with a 6-3, 6-2 upset of defending champion Karolina Pliskova on Saturday.
The Wimbledon champion will meet on Sunday the winner of the later semifinal between Simona Halep and Sloane Stephens.
The final will be the first on American soil for Muguruza, who lost to Pliskova in last year’s W&S semifinals. The Spaniard had lost six straight matches against Pliskova since winning their first in 2013.
Muguruza clinched the win when the top-ranked Pliskova sailed a forehand long on the fifth match point. Pliskova, who played part of one match and all of another on Friday after rain forced postponements on Thursday, had 28 unforced errors to Muguruza’s 13.
Muguruza was coming off playing the tournament’s longest match, a 2-hour, 45-minute three-set win over Svetlana Kuznetsova on Friday. That followed a 2-hour, 18-minute win over Madison Keys on Thursday, when she fought off three match points.
Muguruza took charge early on Saturday, breaking Pliskova in the first and last games of the first set.
She gained a second-set edge with a backhand winner on break point for a 4-2 lead before closing it out in 1 hour, 19 minutes.
