Three-time defending champion Iga Swiatek reached the Qatar Open semifinals by beating Elena Rybakina 6-2, 7-5 on Thursday. Swiatek, ranked No. 2, will face either Jelena Ostapenko or Ons Jabeur for a spot in the final. “The second set I felt like she raised her level so I needed to do that too," Swiatek said after defeating Rybakina in what was a rematch of last year's title match.
