Top-seeded Karolina Pliskova has advanced to the Prague Open final by beating Yanina Wickmayer of Belgium 6-4 7-5.
Pliskova produced an ace on her first match point on Friday, one of 11 aces for the hard-hitting, 14th-ranked Czech.
Pliskova will face qualifier Lucie Hradecka in an all-Czech final. Hradecka beat another Czech, unseeded Katerina Siniakova, 6-2 4-6 6-4.
In her third final of the year, Pliskova will seek her first title of 2014, and fourth overall.
Hradecka converted her first match-point with a service winner to advance to her seventh career final. She has never won a tournament.
The 18-year-old Siniakova was a set down and trailed 4-2 when she came back, winning four straight games and taking the second set on her fifth set point when Hradecka double-faulted.
