Serena Williams's two withdrawals in a row from Indian Wells and Miami allow Angelique Kerber to come back to be World No. 1 despite she had a very poor 2017 season so far. At the third place there is Karolina Pliskova, who has 1,500 points less than Serena. Dominika Cibulkova overcomes Simona Halep at the fourth place and achieves her career-high ranking. Agnieszka Radwanska loses two places, she is now World No. 8, while Indian Wells finalist Svetlana Kuznetsova earns one place to be World No. 7. The champion Elena Vesnina achieves her career high ranking at No. 13, while Kristina Mladenovic, who reached the semifinals in California, and Anastasia Pavlyuchenkova break into the top 20. Irina Camelia Begu breaks into the top 30, Katerina Siniakova in the top 40. The former Indian Wells and Miami champion Victoria Azarenka, who will return to the competition in summer after giving birth last December, drops to the World No. 48.
