When King finally accepted Riggs' chauvinistic challenge and took him on in what became known as the Battle of the Sexes, she won in three straight sets: 6–4, 6–3, 6–3. The historic triumph lived on as a symbol of women’s achievement in sports and progress in society.
It also led to a few more historic firsts for women in her name: In 1973, he US Open became the first sporting event to offer equal prize money for the women’s and men’s tournaments, and in 2006 the National Tennis Center (where the US Open is played) was renamed the USTA Billie Jean King National Tennis Center, making King the first woman to have a sports stadium named for her.

When the angry official attacked me in that first race, it was a frightening, humiliating moment,” she said. “But it was also radicalizing. It made me realize that people didn’t believe in women’s capabilities, so I was determined to finish the race no matter what, even on my hands and knees if I had to, to prove women could do it.”
