Caroline Wozniacki, who endured a 1-5 stretch on European clay, is now playing with a blacked-out racket. She has been sponsored by Yonex since 2011, but played with Babolat before that. It’s unclear what frame the former No. 1 is using, but she told reporters in Eastbourne that she's experimenting with the frame to gain more power.

“I’m just tinkering a little bit with my racket,” Wozniacki said. “I’m still under contract with Yonex, so we’re just trying to figure out a racket that can help me a little bit more with my game.

“I just feel like I needed a little bit more power and the racket will help.”
