Twenty-seven year old Wozniaki, the world number two, beat Angelique Kerber 2-6, 7-6, 6-4 in a game that saw her save a match point. 

She will now play in the final at Eastbourne for the second year in a row. 

Immediately afterwards in her on-court interview, Wozniaki described the match as "tough".

"I was down match point and I think I got a little lucky hitting both lines, and then I somehow managed to get through," the Dane said. 

"I always have tough matches against Angie, and I knew it wasn't going to be an easy one today."

Germany's Kerber started the match as the much more aggressive player and took a double break early on, eventually winning the first set in under half an hour.

Wozniaki then took a 4-1 lead in the second set but could not capitalise initially, with Kerber coming back to such an extent that Wozniaki had to save a match point, before taking it to a tiebreak. 

Having won that Wozniaki then managed to save three break points in the third before then taking one of her own to win the final set 6-4.  

On the other side of the draw Sabalenka, who has made her debut at Eastbourne this year, beat former world number two Agnieszka Radwańska of Poland 6-3, 1-6, 6-3  in a match that saw 14 breaks of serve. 

Unlike Wozniaki, 20-year-old Sabalenka started as the much more aggressive player and maintained it throughout the match, making 54 winners compared to Radwanska's 11. 

"It's not easy to play against players like Agnieszka, because she's so good," Belarus player Sabalenka said afterwards.

"She puts all the balls in, and she can read the game, like I said yesterday. 

"I'm so happy that I did it finally."

She said she is hugely excited for tomorrow's final, having admired Wozniaki while growing up.

"I remember one situation with Wozniacki, she was running and put all the balls in, it was the longest point I’ve ever seen," she added.

"I didn't think I would play against them, and tomorrow, it's a good way to find out how to win [against] them."

Tomorrow's final will begin at 12.30pm in the English town.
