Marketa Vondrousova, aged 24, had never progressed beyond the second round at the All-England Club until this year.
However, she is now on the verge of glory after triumphing over Ukraine’s Svitolina – who is also unseeded following her childbirth nine months ago – with a 6-3, 6-3 victory.
Vondrousova is set to face either Aryna Sabalenka or Ons Jabeur in the final on Saturday.
The second semi-final on Thursday will witness a clash between Belarusian second seed Sabalenka and Tunisian sixth seed Jabeur, following the conclusion of the first match on Centre Court.
No matter who emerges victorious, it is certain that the All England Club will crown a first-time champion.”
I can’t quite believe it,” exclaimed Vondrousova, who had never previously played on Centre Court.”I am absolutely thrilled.
Elina is a formidable competitor and a wonderful individual. It was an incredibly challenging match.”
