Kiki Bertens moved through to her second final at the Ladies' Championship Gstaad on Saturday after Sara Sorribes Tormo retired at the close of the opening set of the first semifinal.
The No.2 seed and 2016 runner-up won the opening set, 6-1, when the unseeded Spaniard retired due to a left wrist injury, putting the Dutchwoman through to her second WTA final of the season.
"It's tough always to win a match like this when your opponent has to retire, but I'm happy to be in the final again this year," Bertens said. "Hopefully, I can do a little bit better than last year. I think it's going to be a tough match [tomorrow]."
