September 20, 1973 –
tennis star Billie Jean King beat Bobby Riggs in straight sets, 6-4, 6-3, 6-3, at the Houston Astrodome.
In recent years, a persistent urban legend has arisen (again,) that Bobby Riggs had thrown the tennis match against Billie Jean King, to pay off a purported $100,000 gambling debt he owed to the Mafia.
This is false: this scurrilous rumor should have been put to bed a number of times, not the least of which, when Mr Riggs passed a lie detector test denying that he threw the Battle of the Sexes.
