Two of last week's title-winners inched closer to confirming their spots at the BNP Paribas WTA Finals Singapore presented by SC Global as Seoul champion Jelena Ostapenko and Tokyo champion Caroline Wozniacki each improved their standings in the Porsche Race to Singapore.
On the back of her first title of the season in a staggering seventh final, Wozniacki moved up one spot to No.5, as she looks to qualify for the WTA Finals for the fifth time in her career, and first since 2014.
Ostapenko's second title of the season at the KEB Hana Bank-Incheon Airport Korea Open helped her move up to No.7, and bump Johanna Konta down to No.8.
Both women will look to better their standings at the Dongfeng Motor Open in Wuhan this week, as Wozniacki will face Greece's Maria Sakkari and Ostapenko takes on Barbora Strycova.
Elsewhere in the Top 8, Karolina Pliskova helped her cause in the Race with a quarterfinal showing in Tokyo, and the former World No.1 displaces Elina Svitolina in the No.3 spot in the Race this week.
The Ukrainian, owner of a WTA-leading four titles this season, is still in prime position to qualify during the Asian swing at No.4 in the Race.
