There's little movement at the top of the pile this week - but there are plenty of players shooting up the rankings further down the field.
There are no movers in the Top 10, although there is a bit of a shuffle in the Top 20, with Angelique Kerber, CoCo Vandeweghe and Sloane Stephens all moving up one place, and Agnieszka Radwanska and Elena Vesnina dropping one; Madison Keys falls two places, while Anastasia Pavlyuchenkova rises three. Elsewhere, Peng Shuai drops four places, from No.25 to No.29, after failing to defend her Tianjin title, falling in the semi-finals to Maria Sharapova in straight sets.
Here are some of the week’s biggest ranking movers:
Maria Sharapova (+29, No.86 to No.57): The Russian won her first title in two years when she beat Aryna Sabalenka of Belarus, 7-5, 7-6(8), to win the Tianjin Open.
Jennifer Brady (+10, No.70 to No.60): The American sailed to the semifinals at the Prudential Hong Kong Tennis Open, winning each of her matches in straight sets as she breezed past Misa Eguchi, Zhang Shuai and Nicole Gibbs. Seventh seed Daria Gavrilova proved a trickier proposition, though, defeating her 6-0, 7-5.
Johanna Larsson (+10, No.89 to No.79): The 29-year-old had a solid tournament at the Upper Austria Ladies Linz, with victories over Jana Cepelova and Varvara Lepchenko, both in straight sets.
Mihaela Buzarnescu (+16, No.105 to No.89): The Romanian qualifier enjoyed a great run in Linz, beating Anett Kontaveit, Ajla Tomljanovic and Belinda Bencic before losing in the semi-finals, 6-3, 7-6(3), to second seed Barbora Strycova.
Nicole Gibbs (+9, No.114 to No.105): The American had a touch of fortune as she flew to the Hong Kong quarterfinals, as Elina Svitolina withdrew from their round of 16 match. She had fought hard to get past Valentini Grammatikopoulou in the round of 32, 4-6, 6-2, 7-5.
