Quebec City, QC -- (Sports Network) - Nadia Petrova of Russia and American Bethanie Mattek will play for the title of the Bell Challenge after both won semifinal matches on Saturday.

The top-seeded Petrova ended American Angela Haynes' magical run with a 6-1, 6-3 victory, while the sixth-seeded Mattek notched a 7-6 (7-4), 6-3 triumph over Canada's Aleksandra Wozniak.

Petrova will try for her ninth career title and second of 2008, having captured the crown in Cincinnati before the U.S. Open. She has also lost twice in finals this year, falling to Agnieszka Radwanska in the title match at Eastbourne prior to Wimbledon and losing to Jelena Jankovic in Stuttgart last month.

Haynes had reached the main field as a lucky loser and was participating in her first WTA semifinal.

Mattek had never before reached a WTA final. She lost in the semifinals twice earlier this year -- at Birmingham before Wimbledon and at the East West Bank Classic in Los Angeles in July.

Petrova and Mattek will play for the first time on Sunday.

The 2008 Quebec champion will collect $28,000.
