Teenager Donna Vekic upset the seedings for a third time to reach the WTA AEGON Classic final in Edgbaston on Saturday.
Vekic, 16, defeated former champion Magdalena Rybarikova 7-6 (7-5) 1-6 6-3 in a rain-interrupted match to move into the final of the Wimbledon warm-up event.
It is already the second final of Vekic's brief career, and Saturday's progress has taken her one step further than Maria Sharapova, on her debut in Birmingham 10 years ago.
The Croatian has been strongly compared to a young Sharapova and asked if she knew about that, the teenager wisely set them aside.
"That's very nice but she has her career and I have my career," she said.
There were though moments when doubts arose whether Vekic could handle the combined threat of Rybarikova and the damp, blustery conditions.
She threw her racket in frustration when she dropped serve to go 4-5 down in the first set, and looked increasingly concerned as the games ran steadily away from her in the second set.
However she was helped, she claimed, by the rain delay just before the end of it.
"I wasn't playing very well and it gave me a chance to spend some time with my coach (David Felgate)" she said.
"I wasn't serving very well and so after that I tried to get a higher percentage (of first serves) in. It helped.
"I was also nervous, but now I am very excited about reaching the final. I don't want to think about it too much though now."
Her opponent in Sunday's final will be Daniela Hantuchova, the former world No 5 from Slovakia, who beat American Alison Riske 5-7 6-1 6-4 to reach her first singles final since February last year.
