LINZ, Austria (AP) — Alison Riske defeated Chinese qualifier Wang Xinyu 6-3, 7-5 on Wednesday to set up an all-American semifinal against Danielle Collins at the Upper Austria Ladies Linz.
The third-seeded Collins, who is pursuing her third title of the season, beat Alison Van Uytvanck of Belgium 7-5, 6-3.
Simona Halep also advanced to the semifinals, rallying to beat Jasmine Paolini of Italy 4-6, 7-5, 6-0.
Riske and Collins have played each other once before — in Rome in 2018, when Collins won in three close sets.
The 73rd-ranked Riske is going into her second semifinal this year, after reaching the final in Portoroz, Slovenia in September.
