Nine dad-daughter teams with game
Kim and Lei Clijsters
She says she got her legs from her father -- and Kim Clijsters inherited well. Lei Clijsters had a 20-year pro soccer career that included two World Cup appearances for Belgium. After the center back retired in 1993, he turned his focus to his tennis-playing daughters, Kim and Elke, managing their careers the way he played -- without bringing attention to himself. In 2003, Kim reached No. 1 in the world. Two years later, she defeated Mary Pierce in the U.S. Open for her first of four Grand Slam titles. But eight months before Kim's second U.S. Open win, in 2009, Lei died of cancer. Still, his presence was felt. As Kim, now 29, waited anxiously to face Serena Williams in the final, a radio played a Barry White song featured at her dad's funeral. "I suddenly felt calm," she says. "And, of course, I won the match."
