Prague, Czech Republic (SportsNetwork.com) - Top-seeded Karolina Pliskova and qualifier Lucie Hradecka will battle in Saturday's all-Czech final at the Prague Open.

Friday's semifinals saw the world No. 14 Pliskova beat Belgian Yanina Wickmayer 6-4, 7-5 and Hradecka outlast 18-year-old fellow Czech Katerina Siniakova 6-2, 4-6, 6-4 at this clay-court event.

Pliskova's victory was her WTA-leading 27th match win of the year.

"I'm still not happy with the way I'm playing here, but on the other hand I'm never happy," said Pliskova. "At least I didn't have a big gap in concentration like in my last matches, and I'm happy that I can save some energy for the final."

Pliskova and Hradecka have split two career matchups, but Hradecka prevailed in a second-rounder here in Prague in 2011.

The 23-year-old Pliskova is 3-5 in her career WTA finals, including runner-up finishes in Sydney and Dubai this year.

Hradecka, who will turn 30 later this month, is winless in five career finals.

Saturday's winner will claim $43,000.
