Already guaranteed of becoming the eighth Czech to reach the WTA Tour's top 10, Karolina Pliskova celebrated with a win.
Karolina Pliskova celebrated her impending debut in the WTA Tour's top 10 with a first-up win at the Bank of the West Classic on Thursday.
Without hitting a ball in Stanford, Pliskova was already assured of entering the WTA's elite bracket at the next rankings release on Monday - and now it could be a matter of how far into the top 10 she will go after a 7-5 6-2 win over Kimiko Date-Krumm.
Pliskova, ranked 11th, beat Date-Krumm at the WTA Premier event for the second year running, and could potentially climb as high as eighth - results pending.
The Czech's draw opened up when 44-year-old Date-Krumm upset Sabine Lisicki, and opportunity further beckons for Pliskova after top seed Caroline Wozniacki was dumped out of the hard-court tournament.
American Varvara Lepchenko ousted world number five Wozniacki 6-4 6-2, leaving Pliskova as the only seed in the top half of the draw.
Second seed Agnieszka Radwanska avoided the same fate, fighting back to beat qualifier Misaki Doi 1-6 6-2 6-0.
Next up for the seventh-ranked Radwanska is fifth seed Angelique Kerber, who was a 6-4 6-3 victor over Ana Konjuh.
