The "Best of Belgium" exhibition event, renamed the "Best of World" after Justine Henin was replaced by Serena Williams in the match due to an elbow injury, set a new world record for attendance at a tennis match with 35,681 spectators surpassing the previous record of 30,472 set by the "Battle of the Sexes" match in 1973 featuring Billie Jean King + Bobby Riggs.
Kimmie defeated an injured ReRe (foot) 6-3, 6-2 with 18-time Grand Slammer Martina Navratilova serving as chair umpire and Roland Garros champ Francesca Schiavone making a surprise appearance.
"I was here often as a little girl to come and watch football," said Kimmie referring to her late father, Leo, who played soccer in the stadium. "That I can actually play here is very special and emotional. I said to myself a few times: 'Remember this moment well.'"
The event, held at King Baudouin Stadium, raised money for charity and marked Belgium's 6-month presidency of the European Union. It concluded with a concert and fireworks.
