NÜRNBERG, Germany - No.2 seed Katerina Siniakova pulled off an emphatic comeback to reach the Nürnberger Versicherungscup semifinals, knocking out American Madison Brengle, 1-6, 6-4, 6-0.
"I feel ready and really warmed-up at the beginning of these matches," Siniakova said after the match.
"Maybe I might as well miss the first set and come on court for the second and third!" she added with a laugh.
Siniakova suffered a slow start but made up for lost time in the deciding set, wrapping up the win over the former World No.35 in 89 minutes on Centre Court.
"It doesn't matter to me, so long as it ends with a victory!"
The WTA Doubles Co-No.1 - alongside partner Barbora Krejcikova - was playing her second quarterfinal of the clay court season, having reached the last eight at the J&T Banka Prague Open, where she fell to countrywoman Barbora Strycova.
"This season has been tough for me. I feel good on the court, but the victories haven't been there. I'm really happy with this week, winning three tough matches in a row. Hopefully, I'll take confidence from this, and it's not the end yet."
Brengle, by contrast, was playing just her second WTA clay court main draw of 2019, after competing for the USTA Roland Garros Wildcard Challenge on the ITF Pro Circuit. The American nonetheless played solid tennis this week in Nürnberg, upsetting No.7 seed Evgeniya Rodina and winning the first five games against Siniakova.
Though the Czech managed to get on the board at the tail end of the opening set, Brengle held on and broke to start the second set.
Emerging from four consecutive service breaks, Siniakova began to get into the match as she exchanged holds of serve until the all-important 10th game, where she converted the second of two set points on Brengle's serve.
The final set went entirely to the Czech youngster, who saved a break point in the opening game and ultimately roared to victory, winning the match at love.
Standing between Siniakova and her first WTA singles final of the season will be either Tamara Zidansek or Veronika Kudermetova, who play the final quarterfinal match on Thursday.
"I expect another tough match. It'll be a good opponent no matter who, so I'm just going to fight, and hopefully I'll win again."
