Key Storylines

Serena is back: The last time we saw Serena Williams on a tennis court was at Wimbledon last summer, where she was forced to retire due to a leg injury in her opening round against Aliaksandra Sasnovich. The 23-time major champion will return to competition in Eastbourne in doubles with Jabeur, with an eye toward preparing for her singles return at Wimbledon. 

Former champion Pliskova finding form: It's been a tough season for the big-serving Czech, who broke her arm during the off-season and has made just one semifinal this season. But Pliskova made great strides last week in Berlin, tallying wins over Kaia Kanepi and Bianca Andreescu before bowing out in two tight sets to Gauff. A finalist at Wimbledon last year, Pliskova could be one to watch over the next three weeks.

Badosa and Krejcikova ready for a crash course: Both women did well at Wimbledon last summer, making the Round of 16. After early exits from Roland Garros, Badosa and Krejcikova stayed on the sidelines to rest and prepare. Eastbourne will be their grass-court event before Wimbledon.
