World number one Caroline Wozniacki, today Thursday, fell to a shocking defeat at the hands of Russia’s Daria Kasatkina.
Wozniacki had earlier routed 16-year-old Russian wild card to make the quarter-finals and had been heavily tipped to lift the St. Petersburg Ladies’ Trophy, but was beaten 7-6, 6-3 by 20-year-old Kataskina, who produced a stunning performance to reach the semi-finals.
Kasatkina was dominant in the tiebreak 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, who’s ranked 23rd in the world 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.
The Russian will next face defending champion Kristina Mladenovic, who continued her impressive run with a 6-4 6-3 win over Czech Katerina Siniakova in the quarter-finals.
