After winning her biggest career title at the Western & Southern Open, Kiki Bertens has her eyes set on Singapore.
The Dutch No.1 moves up four spots in this week's Porsche Race to Singapore update, putting her in contention to qualify for the BNP Paribas WTA Finals Singapore presented by SC Global.
Bertens was runner-up in doubles at the year-end championships a year ago, but would be looking to qualify for the singles field for the first time.
The now-World No.13 saved a match point to defeat World No.1 Simona Halep in Sunday's championship, completing her week in Ohio with four straight Top 10 victories to win her first Premier 5 title.
Cincinnati semifinalist Petra Kvitova is the lone other move up in the Top 8, as she swaps spots with Australian Open champion Caroline Wozniacki for the No.3 spot.
Wozniacki was forced to retire due to injury in her second round match against Bertens in Cincinnati.
Elsewhere in the Race, two other breakout performers in Cincinnati make huge gains. Fast-rising Belarusian Aryna Sabalenka moves up six spots to No.22 after reaching the semifinals, while Acapulco champion and Cincinnati quarterfinalist Lesia Tsurenko moves up nine slots to No.26.
