Some people forget this part though In 1973, Riggs saw an opportunity to both make money and to draw attention to the sport of tennis. He came out of retirement to challenge one of the world's greatest female players to a match, claiming that the female game was inferior and that a top female player could not beat him, even at the age of 55. After Billie Jean King declined, he challenged Margaret Court, 30 years old and the top female player in the world. In their May 13, 1973, Mother's Day match in Ramona, California, Riggs used his drop shots and lobs to keep an unprepared Court off balance. His easy 6–2, 6–1 victory landed Riggs on the cover of both Sports Illustrated and Time magazine. The match was called the "Mother's Day Massacre". Following Court's loss to Riggs, King accepted his challenge, and on September 20, 1973, the two met in the Houston Astrodome, in a match billed as The Battle of the Sexes. King beat Riggs, 6–4, 6–3, 6–3 for the $100,000 winner-take-all prize. Unlike a similar match between Jimmy Connors and Martina Navratilova in 1992, in which the rules were altered to favor the female player, this match was played using the normal rules of tennis. According to an extensive article by the ESPN program Outside the Lines,[10] Riggs took advantage of the overwhelming odds against King and threw the match to get his debts to the mob erased. This would confirm the suspicions held by many of Riggs' peers, including Don Budge. On the other hand, the article says Riggs' close friend and estate executor Lornie Kuhle vehemently denied Riggs was ever in debt to the mob or received a payoff from them.
