The American will face Marina Erakovic of New Zealand on Saturday with a chance to reach the finals. Erakovic beat Ajla Tomljanovic of Croatia 2-6, 6-1, 7-5.

Trailing 6-1, 6-5, McHale rallied to reach her second Quebec semifinal.

"I thought it was an extremely tough match," McHale said. "Polona started off playing really, really well, and it took me a while to get used to her game, but I just kept fighting and taking it point by point, and I was serving well today as well, which helped a lot, and I'm really excited to be into the semifinals now."

Canadian teenager Eugenie Bouchard also advanced to the semis by beating Kristina Mladenovic of France 6-3, 6-2. Bouchard will face Lucie Safarova of the Czech Republic, who beat American Lauren Davis 6-2, 6-4.
