World No. 1 Serena Williams jokes that Rafael Nadal, who has won six of the eight tournaments he played this year and reached two other finals, is competing with her comeback success.

“I think he's performed great,” she told reporters. “I think he's been doing a great job."

She then added with a smile: “I think he's trying to compete with me with like his comeback, so...Yeah, I'm going to have a talk with him about that."
