Didn’t he beat Billie Jean King the first time?
Riggs threw that match.
Riggs defeated Margaret Court before losing to Billie Jean King.
I think in 1992, a 40 year old Jimmy Conners and 35 year old Martina Navratilova had a pay-per-view match where Conners had only one serve and had to play the Doubles Court, Conners won easily.
