Alison Riske upsets No. 10 Carla Suarez Navarro to reach quarters

Thursday August 6th, 2015

STANFORD, Calif. (AP)—American Alison Riske changed her schedule this season to include the Bank of the West Classic for a variety of reasons. One of them was to change her luck.

The 59th ranked Riske did just that, beating third-seeded Carla Suarez Navarro 6–4, 6–4 on Wednesday to reach the quarterfinals.

Riske, making her main draw debut in the event, beat a top-10 player for the first time in nearly two years and the second overall in 12 tries.

Germany's Mona Barthel also knocked off a seeded player, beating sixth-seeded compatriot Andrea Petkovic 5–7, 6–2, 7–6 (4) and could next play top-seeded Caroline Wozniacki, who makes her first appearance Thursday night.
