On 8 July 2010, an exhibition match between Clijsters and Henin was scheduled as an attempt to set a new world record for largest attendance at a tennis match. The contest took place at the King Baudouin Stadium and was a part of the Best of Belgium national festival. After Henin needed to withdraw from the match due to an elbow injury, Serena Williams was chosen as a replacement. Although Williams injured her foot several days before the match, she chose to play. Clijsters defeated Williams in straight sets. A total of 35,681 people attended the match, breaking the world record of 30,472 set in 1973 by the Battle of the Sexes between Billie Jean King and Bobby Riggs.
