TIL Desk Sports/ World number one Caroline Wozniacki suffered her first defeat since lifting the Australian Open trophy when she was edged out 7-6(2), 6-3 by Russia’s Daria Kasatkina in the quarter-finals at the St Petersburg Ladies’ Trophy on Friday.
The 20-year-old Kasatkina was dominant in the tie-break to claim the opening set and won three of the last four games of the match against Wozniacki, who had fought hard to get back on serve halfway into the second set.
“She just won the Australian Open, and since I beat her, it means I was playing really well,” Kasatkina said. “I was just trying to play point-by-point and focus on the rally.”It was Kasatkina’s second career win over a reigning world number one, having beaten Angelique Kerber when the German held the top ranking in Sydney last year.
World number 23 Kasatkina will next face defending champion Kristina Mladenovic, who continued her strong run with a 6-4, 6-3 win over Czech Katerina Siniakova in the quarter-finals.
Earlier in the day, two-time Wimbledon winner Petra Kvitova booked her place in the semi-finals with an attacking masterclass to defeat second seed Jelena Ostapenko 6-0, 6-2.
