Five of the eight women’s quarterfinalists have either held the No. 1 ranking or won a Major title. However, four of the players with those credentials are in the top half of the draw, setting up a fantastic slate of matches Friday.

The winners of the last two Grand Slam tournaments will square off in the first Friday quarterfinal. Wimbledon champion Ashleigh Barty, the World. No. 1, is looking to reach her second straight Cincinnati semifinal. Standing her in way is French Open winner Barbora Krejcikova, who she defeated in the Wimbledon Round of 16. Barty has won four titles this season, while Krejcikova owns three.

A pair of left-handed Major champions will collide in Friday’s second quarterfinal, with both seeking a spot in their third Cincinnati semifinal.

She’s facing two-time Wimbledon winner Petra Kvitova, who has won eight of the 15 meetings between two.
 Karolina Pliskova vs Paula Badosa
The only former Western & Southern Open champion remaining in this year’s field is Karolina Pliskova. The 2016 Cincinnati winner, Pliskova ascended to the WTA’s No. 1 ranking the summer after her title here. She takes on 23-year-old Paula Badosa who is seeking a spot in her fifth semifinal of the year.
 Belinda Bencic vs [WC] Jil Teichmann
It will be a Swiss showdown as Belinda Bencic faces countrywoman Jil Teichmann in Friday’s quarterfinals. Bencic is seeking her 10th straight match victory after winning the gold medal at the Tokyo Olympics before coming to Cincinnati. Teichmann upset No. 2 seed Naomi Osaka on Thursday night to reach her first Cincinnati quarterfinal. Since reaching the semifinals at Dubai in March, Teichmann had won just three matches before claiming a trio of victories this week.
