It began like no other tennis match, with a piglet handed over before a single ball was struck. But what followed on 20 September 1973 at the Houston Astrodome became one of the most important moments in sporting and social history.
An estimated 90 million people worldwide watched Billie Jean King defeat Bobby Riggs in a best-of-five contest that went far beyond tennis. The spectacle, the prize money and the theatre mattered, but the symbolism mattered more. This was not just entertainment; it was a statement about equality, power and opportunity.
More than five decades on, the match still resonates whenever exhibitions are labelled a “Battle of the Sexes”, even if the stakes today are far lower than they were then.
A match bigger than tennis
At the time, King was 29, at the peak of her career and already a multiple Grand Slam champion. Riggs was 55, a former Wimbledon winner who had reinvented himself as a provocateur, publicly claiming women’s tennis was inferior and undeserving of equal reward.
King later made clear the significance of the occasion, saying the match was about social change and politics, not sport, according to BBC Sport. She knew defeat would reinforce damaging stereotypes at a moment when women’s sport was fighting for credibility and fairness.
The context of inequality
Professional tennis had only recently entered the Open era. Prize money gaps were stark. When King won Wimbledon in 1968, she earned £750, while the men’s champion received £2,000. In response, King and eight other players – later known as the Original Nine – formed a breakaway women’s circuit, laying the foundations for the Women’s Tennis Association.
Their stand eventually led to the creation of a unified women’s tour in 1973, the same year as the match against Riggs.
Provocation and pressure
Riggs spent months stoking controversy with inflammatory comments, openly embracing the role of villain. He targeted King deliberately, knowing her public identity was closely tied to the women’s rights movement.
King later recalled she accepted the challenge only after Margaret Court, then the world number one, was comprehensively beaten by Riggs earlier that year, according to BBC World Service. That loss heightened the pressure and raised the stakes even further.
Mind games before matchday
The build-up was relentless. Riggs mocked, postured and sought to distract, while King prepared meticulously, studying his game and his tactics. She was careful to play along with the showmanship without letting it undermine her focus.
When Riggs crossed the line, King publicly called him out, later explaining she wanted to be clear that his sexism was not acceptable, according to WTA.
A spectacle with symbolism
Matchday was pure theatre. King was carried into the arena on an ornate litter, Riggs followed in a rickshaw pulled by women in novelty shirts. They exchanged gifts: a lollipop from Riggs, a piglet from King – a pointed reference to his self-proclaimed chauvinism.
Despite the carnival atmosphere, the match itself was uncompromising. There were no concessions. They played five sets, on a standard court, under immense noise and scrutiny.
How King won it
The opening set proved decisive. King recovered from an early deficit to take it, a moment she later described as psychologically crushing for Riggs, according to BBC Sport.
From there, her strategy was clear. She controlled rallies from the baseline, forced Riggs to cover the court and exposed the limitations of a 55-year-old who had not competed seriously in years. King won in straight sets, sealing victory after Riggs double-faulted under pressure.
A victory that echoed beyond sport
As King lifted the trophy, the impact was immediate and lasting. Riggs admitted he had underestimated her. Later rumours suggested darker explanations, but history has focused on what the moment represented.
King has since said women felt empowered and men often approached her emotionally, describing how the match reshaped their thinking about gender and opportunity, according to BBC Sport.
Legacy of a defining moment
King went on to finish her career with 39 Grand Slam titles, but her influence stretches far beyond statistics. The victory over Riggs became a cultural reference point, cited by politicians, athletes and activists alike.
Long after the cheers faded, the match remained what King always believed it was: not just a contest, but a turning point that showed sport could challenge society, not merely reflect it.
