Billie Jean King opened the door for women in tennis to come out as gay and gave Ilana Kloss the confidence to come out herself. That turned out to be a bonus for King's bravery, as the two have now been together for decades! Kloss was an excellent tennis player in her own right, but was more active as a doubles player than she was in singles. Her career highlight was winning the US Open Doubles Tournament in 1976.
Since retiring, Kloss has stayed involved with the sport. She's been the commissioner of World Team Tennis since 2001, as well as coaching several players one on one, although she does less of that now she's in her 60s. In 2018, she and King branched out into a completely different sphere of sport; they made a joint investment and became minority owners of the LA Dodgers baseball team.
