King also completed the Triple Crown at Wimbledon (winning the singles, women's doubles, and mixed doubles titles in the same year), thus becoming the first, and only, player to do so at Wimbledon in the Open Era. In none of the preceding tournaments, however, did King play Court. Their rivalry resumed in the final of the Virginia Slims of Nashville tournament, where Court won for the third time in four matches against King in 1973. (This was the last ever singles match between those players, with Court winning 21 and King 13 of their 34 matches.) Three weeks later at the US Open, King retired from her fourth-round match with Julie Heldman while ill and suffering from the oppressive heat and humidity. When Heldman complained to the match umpire that King was taking too long between games, King reportedly told Heldman, "If you want the match that badly, you can have it!" The Battle of the Sexes match against Bobby Riggs was held in the middle of the Virginia Slims of Houston tournament. King won her first and second round matches three days before playing Riggs, defeated Riggs, won her quarterfinal match the day after the Riggs match, and then lost the following day to Casals in the semifinals 7–6, 6–1. According to King, "I had nothing left to give." To end the year, King won tournaments in Phoenix, Hawaii, and Tokyo and was the runner-up in Baltimore.
