As the US hard-court swing begins, the Top 20 are mostly holding firm to their spots in the rankings. Karolina Pliskova remains on top of the tree, with Simona Halep, Angelique Kerber, Garbiñe Muguruza and Elina Svitolina rounding out the Top 5.
The only exception is Latvia's Anastasija Sevastova, up one place to No.16 after her run to the quarterfinals at the Ericsson Open, where she was seeded second but was knocked out by eventual champion Katerina Siniakova.
