Angelique Kerber was the two-time defending champion, but she lost in the second round to Kristina Mladenovic.

Laura Siegemund won the title, defeating Mladenovic in the final, 6–1, 2–6, 7–6^(7–5).

As a result of Kerber's loss, Serena Williams regained the world No. 1 ranking, despite being on pregnancy leave. This tournament also marked the return of Maria Sharapova to the WTA Tour, after serving a 15-month suspension for doping offences.

The top four seeds receive a bye into the second round.
