British number one Johanna Konta booked a place in the final of the Aegon Open in Nottingham with a 6-2 7-5 win over Magdalena Rybarikova.
Top seed Konta, 26, maintained her record of having yet to drop a set in the tournament as she closed in on her first WTA title on home soil.
Playing in the semi-finals of the competition for the first time, Konta twice broke Rybarikova in the opening set.
After swapping breaks in the second, the Slovakian double-faulted in the 11th game to gift Konta the advantage and the Briton served out the match.
Konta will now take on Donna Vekic in Sunday's final after the Croatian caused an upset by outlasting fifth seed Lucie Safarova 7-6 (7/5) 3-6 7-6 (7/4) in three tough sets.
Russia's Natalia Vikhlyantseva upset Ana Konjuh in straight sets at the Ricoh Open in 's-Hertogenbosch to reach her first WTA final.
Vikhlyantseva will meet Estonia's Anett Kontaveit in Sunday's showpiece after beating fifth seed Konjuh 6-3 7-5.
Unseeded Vikhlyantseva, who had lost her previous six matches before this tournament, broke Konjuh in the fourth game of the opening set and hit back from 4-5 down in the second to win the last three games.
Kontaveit booked her place in the final by defeating Lesia Tsurenko 6-3 6-7 (0/7) 6-2.
World number 49 Kontaveit built a 4-1 lead in the opening set and although her errors were punished in a one-sided second-set tiebreak, she held the edge on the big points in the decider to triumph in two hours.
