On Sept. 20, 1973, in their so-called “Battle of the Sexes,” tennis star Billie Jean King defeated Bobby Riggs in straight sets, 6-4, 6-3, 6-3, in the Houston Astrodome. It was the first time a woman had played against a man in such a venue, and it was an historic event with much media hype and an astounding amount of betting in Las Vegas with the odds in Riggs’s favor.
