RIYADH, Saudi Arabia — Amanda Anisimova reached the last four of the WTA Finals by beating second-ranked Iga Swiatek 6-7 (3), 6-4, 6-2 on Wednesday.
The American, 24, earned her second consecutive victory over Swiatek since losing to the Polish player 6-0, 6-0 in the Wimbledon final.
Anisimova, ranked No. 4, had also eliminated Swiatek in the US Open quarterfinals.
Anisimova got the first break of serve in the contest to take the second set to force a decider. She faced only four break points and saved each.
Elena Rybakina, who had already advanced to the semifinals, completed her round-robin phase with a 6-4, 6-4 victory over Ekaterina Alexandrova.
Rybakina and Anisimova will learn their semifinal opponents after Thursday’s final round-robin matches: top-ranked Aryna Sabalenka plays defending champion Coco Gauff, and Jessica Pegula faces Jasmine Paolini, who has already been eliminated.
