Petra Kvitova and Lucie Safarova will meet in an all-Czech final at the Connecticut Open after the compatriots enjoyed straight sets wins in their respective semi-final matches in New Haven.
Defending champion and second seed Kvitova found herself 5-3 down in the first set against Caroline Wozniacki but stormed back to win 10 of the next 11 games to secure a 7-5 6-1 win over the Dane.
Earlier, fourth seed Safarova ended Ukrainian Lesia Tsurenko's giant-killing run by fending off some late resistance for a 6-2 7-6 victory.
Kvitova has a 6-0 career record against fellow left-hander Safarova but is not taking the final for granted.
"Her game is improving a lot," Kvitova said of her sometimes practice partner Safarova in a courtside interview.
"We know each other well from Fed Cups and off the court as well. She's very dangerous and fast. I think the court can suit her game as well.
"It's nice to have a Czech final for sure. It's amazing how many players we have right now in the top 10."
In the other semi-final, world number six Safarova breezed through the opening set and went two breaks up in the second before 46th-ranked lucky-loser Tsurenko mounted a stirring fightback.
Tsurenko, who had upset fifth-seeded Czech Karolina Pliskova 6-2 6-2 in the quarter-finals and did not drop a set on her way to the last four, broke her opponent's serve four times and saved a match point at 5-4 before losing the tiebreak 7-4.
Safarova, an expert doubles player, will be bidding for her seventh WTA singles title, while Kvitova will be chasing her 17th.
Whatever the outcome, Safavora, who lost the French Open final to Serena Williams in June, can reflect on a golden 2015 campaign, highlighted by grand slam doubles titles in Australia and France, and career-high rankings in singles and doubles.
