On her way to the final, Bertens also defeated two more Russian players, Anastasia Potapova and Veronika Kudermetova.

“I’m really satisfied with my performance and with the result I have showed this week. I’m happy to play in the final tomorrow,” Bertens said after Saturday’s match.

“I was pleased to see that half of the stands were colored in orange today. Sorry everyone that I already knocked three players from Russia out of the tournament this week, but I can do nothing about it. I will try to show my best in the final,” she added.

In the tournament’s deciding match Bertens will face off against Kazakhstan’s Elena Rybakina, who beat Maria Sakkari of Greece in their semi-final.
