Karolina Pliskova reached her first ever WTA final by crushing fourth seed Ayumi Morita 6-0, 6-2 at the BMW Malaysian Open in Kuala Lumpur.
The Czech player, who is ranked world No. 127, has not dropped a set in the tournament and needed just 47 minutes to cruise past her Japanese opponent and set up a clash against American Bethanie Mattek-Sands.
Pliskova, 20, admitted she was surprised by the ease of her victory and by how well she has been playing at the tournament.
"I expected a tough match but and I'm surprised it wasn't," she said.
"I've been better in other tournaments but the results were not as good as this. I'm excited to play in my first final and can't wait to see who I'll be playing.
"I'm quite surprised I have yet to drop a set but I did tell myself I must finish the matches off quickly as the weather is really tough.
Pliskova will now face Mattek-Sands in the final after the wildcard came through in straight sets against two-time Grand Slam quarter-finalist Anastasia Pavlyuchenkov.
Mattek-Sands, who has 12 doubles titles to her name, including last week's Dubai Duty Free Championships with Sania Mirza, eased past third seed Pavlyuchenkova of Russia 6-4, 6-1 in 73 minutes.
"This is an important tournament for me as I'll be going for my first singles title. It will mean more to me than my 12 doubles crowns if I were to win it," said Mattek-Sands, who is ranked world No. 197.
"I reached as high as 30 before all my injuries and I hope this is a good start for me to climb up the rankings."
