After winning her first title of the season at the St. Petersburg Ladies' Trophy over the weekend, Petra Kvitova soars into the Top 8 on the latest edition of the Porsche Race to Singapore leaderboard.
Kvitova, who won the WTA Finals when they were staged in Istanbul in 2011, was also a runner-up in Singapore in 2015.
The Czech looks to qualify this season after having missed the past two editions of the BNP Paribas WTA Finals Singapore presented by SC Global, and made an early statement in the race with her win at the Premier-level tournament in Russia over Kristina Mladenovic.
She moves over 100 spots in the Race standings this week, up to No.8 - in a tie with fellow St. Petersburg competitor Julia Goerges. Kvitova defeated Goerges in the semifinals en route to the title in St. Petersburg, but by virtue of Mladenovic failing to defend her title, rose into the Top 10 of the WTA rankings for the first time in her career.

Goerges's run to the final four in Russia moves her up eight spots from No.16.
Otherwise, the rest of the Top 7 remains unchanged from the week following the Australian Open.
Elsewhere in the leaderboard, Taiwan Open champion Timea Babos - who sits on top of the doubles Race after winning the Australian Open with Mladenovic - moves up 43 spots to No.17 in the singles standings.
The Hungarian defeated Kateryna Kozlova to win her second title in the past year, as she's reach a total of four singles finals in the past 12 months.
The No.4 seed in Taipei City, Babos dropped just one set en route to winning the trophy.
The aforementioned Mladenovic is the biggest mover of any this week, however - after snapping a 15-match losing streak dating back to last season with three wins in Russia, moves up 347 places to No.21.
