A successful title defence at the Abierto Mexicano TELCEL presentado por HSBC in Acapulco has catapulted Lesia Tsurenko a whopping 29 places up the Porsche Race to Singapore leaderboard to land at No.14.

The Ukrainian extended her immaculate record in WTA finals to 4-0 with a dramatic three-set defeat of Stefanie Voegele on Saturday, backing up a successful Australian swing that saw her reach the semifinals in Hobart and win rounds in Brisbane and at the Australian Open.

With no event above International level scheduled last week, there are no changes in the Top 8 this week.

The closest move to the higher echelons of the Race belongs to Acapulco quarterfinalist Zhang Shuai, who climbs three places to No.12. It was the Chinese No.2's second consecutive quarterfinal following her run to the same stage in Budapest two weeks ago.

Also making significant moves are the Australian pair of Ajla Tomljanovic and Daria Gavrilova, who have both entered the Top 30 this week. Tomljanovic's semifinal showing in the Indian Wells 125K has given the 24-year-old an eight-spot boost to No.28, while Gavrilova's second semifinal of 2018 in Acapulco sees her climb 16 rungs to No.29.

The eventual champion of the Indian Wells 125K, Sara Errani, sealed her return to the Top 100 in the rankings this week, and also rises 37 places to land at No.35 in the Race. Acapulco finalist Stefanie Voegele and Indian Wells 125K runner-up Kateryna Bondarenko are also new faces in the Race Top 50: Voegele is up a hefty 53 places to No.41, while Bondarenko's 20-place climb lands her at No.44.

Meanwhile, Acapulco semifinalist Rebecca Peterson is yet to crack the Top 100 of the rankings - but she's all the way up to No.49 in the Race with a 38-place jump.
