DOHA: Three-time defending champion Iga Swiatek reached the Qatar Open semifinals by beating Elena Rybakina 6-2, 7-5 on Thursday.
Swiatek will face Jelena Ostapenko, who beat Ons Jabeur 6-2, 6-2, for a spot in the final.
"The second set I felt like she raised her level so I needed to do that too," the second-ranked Swiatek said after defeating Rybakina in what was a rematch of last year's title match.
Rybakina began the year with a 4-2 advantage head-to-head against Swiatek, but now they are tied.
Ekaterina Alexandrova continued her winning run by eliminating sixth-seeded Jessica Pegula 4-6, 6-1, 6-1. The Russian, who is ranked 26th, defeated top-ranked Aryna Sabalenka earlier this week.
"When I saw the draw I thought maybe I will not get very far," Alexandrova said. "But overall so far played great matches here. I hope it continues.”
Alexandrova will face another American player in the semifinals. Amanda Anisimova beat Marta Kostyuk of Ukraine 4-6, 7-5, 6-4 to advance.
