SHENZHEN, CHINA – Naomi Osaka extended her winning-streak to 11 matches after defeating Petra Kvitova of the Czech Republic 7-6 (7-1), 4-6, 6-4 in the first of three round-robin matches at this year’s WTA Finals on Sunday.
Osaka, the Australian Open champion, arrived in Shenzen having won the last two tournaments she played — in Osaka and Beijing.
The two-time Grand Slam champion failed to take advantage of two match points when serving at 5-2 in the third, but nailed down the victory on a third match point when serving in the 10th game.
Kvitova surrendered the encounter when she sailed a backhand crosscourt wide on the final point.
The only other time Osaka played Kvitova came when the she captured this year’s Australian Open final by a score of 7-6 (7-2), 5-7, 6-4.
Osaka’s debut at the yearend final last year in Singapore ended in disappointment when she lost all three of her round-robin encounters.
The 29-year-old Kvitova, the oldest player in this year’s eight-player field, is competing in her seventh WTA Finals. She won the title in her first appearance in 2011, and was also a finalist in 2015.
Osaka is now 1-0 and Kvitova 0-1 in Red Group round-robin action.
Top-ranked Ashleigh Barty of Australia and Belinda Bencic of Switzerland make their WTA Finals debuts playing each other in the next match on Sunday.
