Former World No. 1 Kim Clijsters, 36, says it was her family—especially her daughter Jada, 11, who persuaded her to make a comeback to tennis when she played an exhibition match against Venus Williams, 39, at the opening of the No. 1 court in Wimbledon last year.

Clijsters, a mother of three kids — Jada, Jack, seven and Blake, three, told Tennis World USA: "Being in Australia to do commentary and being so close to the action brought back the passion. I told my husband [Brian Lynch] about it. At the age of 35, I said to myself: 'You see Roger, Venus and Serena, maybe I should try it?' She [Jada] was the one who said to me, 'Mom, you have to come back.' "
