Three-time defending champion Iga Swiatek advanced to the semi-finals of the Qatar Open on Thursday with a straight-sets win over last year's runner-up Elena Rybakina. But the Pole was broken at the start of the second and struggled to catch up for a long time,

After the exits of Rybakina and Pegula, Swiatek is the last survivor among the Doha seeds. “I’m super happy and proud of myself, in the second set I felt she lifted her level,” Swiatek said. She next plays Latvia’s Jelena Ostapenko, who eased past Tunisia’s Ons Jabeur, a former world No. 2, 6-2, 6-2.

The win is Swiatek’s 100th at WTA 1000 level in 121 matches played -- making her the second-fastest to the milestone after Serena Williams

Swiatek dropped a set in Doha for the first time since 2022 -- ending a run of 25 won in a row -- but recovered to advance 6-7 (1/7), 6-4, 6-4 and extend her winning streak at the tournament to 14 matches.

Ostapenko lost to Jabeur last week at the Abu Dhabi Open, 7-6 (4), 7-5, which put her season's singles record at 1-4. But with four straight-set victories this week, including upsets of No. 4 seed Jasmine Paolini and No. 16 seed Liudmila Samsonova, the 2017 Roland Garros champion has found her form.

Iga Swiatek claimed her 100th WTA-1000 match victory by beating Elena Rybakina to reach the semi-finals of the Qatar Open.

Three-time defending champion Iga Swiatek overcame Elena Rybakina 6-2 7-5 to reach the semi-finals of the Qatar Open on Thursday, while Russia's Ekaterina Alexandrova defeated American sixth seed Jessica Pegula.

Sixth-seed Jessica Pegula advanced on Wednesday to the quarterfinals of the Doha Open with a 6-3, 7-5 victory over Daria Kasatkina. The American will next face Ekaterina Alexandrova, who beat Elise Mertens 6-4,
