EPA/WARREN TODACaroline Wozniacki of Denmark celebrates her win over Sloane Stephens of the United States of America after their semi-final match in the Rogers Cup Women's Tennis tournament in Toronto, Canada, 12 August 2017.
Later on Saturday, Halep will be back in action against Svitolina, while Denmark's Wozniacki, the sixth seed, takes on American Sloane Stephens for a place in the final.
Wozniacki, who has the most wins on the WTA Tour this year, is looking for her first tournament title of the year in her sixth final appearance. "I knew I was going to play someone that was really tough today, and I'm just happy with my win and that's really it".
In doubles play, Ottawa's Gabriela Dabrowski and Latvia's Jelena Ostapenko defeated Germany's Julia Goerges and Ukraine's Olga Savchuk 4-6, 6-2, 10-3. But I think I'm ready, I feel strong enough in my legs.
"I got back to the hotel at like 12 (a.m.) and went to sleep at 1".
"I thought she started off really strongly and she was attacking and playing really, really well", Wozniacki said.
"She's having a good year as well - injury free and playing really well", Svitolina said.
The world number two seemed keen to move on, saying, "it's just this match that I will forget it very fast for sure".
