Riggs had been a top men's player in the 1930s and 1940s in both the amateur and professional ranks. He won the Wimbledon men's singles title in 1939, and was considered the World No. 1 male tennis player for 1941, 1946, and 1947. He then became a self-described tennis "hustler" who played in promotional challenge matches. Claiming that the women's game was so inferior to the men's game that even a 55-year-old like himself could beat the current top female players, he challenged and defeated Margaret Court 6–2, 6–1. King, who previously had rejected challenges from Riggs, then accepted a lucrative financial offer to play him for $100,000, winner-take-all.
