🎾 52 years ago today, WSF Founder Billie Jean King made history in the “Battle of the Sexes,” defeating Bobby Riggs in front of 90 million viewers worldwide — and proving that women belong on the biggest stages in sports. Today we’re celebrating with a LaBillieBu vs. LaBobbyBu throwback because equality in sports will never go out of style. 💪✨ #PlayToLead #BattleOfTheSexes
