It took a three-hour quarter-final for the 20-year-old Polish, seeded seventh, to break 36-year-old Kaia Kanepi.

Not an easy match, she says afterwards.

- I had so many break points in the first set that I felt I missed my chance, she says and continues:

- I was quite annoyed and I should have just focused on the next point.

So in the second set, I did just that.

Kanepi won the first set (6-4), but Swiatek managed to equalize by taking home others with 7-6 and could then decide with 6-3 in the last set.

-Det är enkla saker att göra, men de funkar. Det kändes som att hon spelade så snabbt att jag inte kunde hålla ihop, så jag var tvungen att fokusera på mina forehands. Det var tillräckligt, konstaterar hon.

I semifinalen väntar amerikanska Danielle Collins, som tog sig vidare efter att vunnit mot franska Alize Cornet med 7–5, 6–1.

I den andra semifinalen, på torsdag, möter världsettan Ashleigh Barty, Australien, amerikanska Madison Keys, 51:a på världsrankingen.
