Lesia Tsurenko of Ukraine reached her first final in four years after the top-seeded Bianca Andreescu retired with a shoulder injury during their semifinal match at the Thailand Open on Saturday.
Tsurenko, in search of her fifth WTA title, was leading the 2019 U.S. Open champion 7-5, 4-0 when the Canadian stopped playing.
Andreescu entered the match having not lost a set this week. The former world No. 23 fought from 3-5 down to take the first set and reeled off eight straight games before Andreescu retired with a right shoulder problem. "Bianca is such an amazing player.
She is capable of hitting all kinds of shots and gave so much trouble today," Tsurenko, now ranked 136th, said from Hua Hin. "But I was just fighting, and I told myself positive things that I can do it.
