When Billie Jean King defeated Bobby Riggs in 1973, tennis's transformation began, which today gives female tennis players the same amount of prize money as men in the Grand Slam tournaments and otherwise equal rights.
In Sunday's match in Dubai, world number one Aryna Sabalenka will face Nick Kyrgios, who is currently ranked 671st in the world and has barely played at the elite level in recent years.
The only similarity is that it's a boy and a girl, says the now 82-year-old Billie Jean King to the BBC about the successor to "Battle of the Sexes."
Our match was about social and cultural change. Mine was truly political. I knew I had to beat him to bring about change.
Former world number one Garbine Muguruza doesn't think Sabalenka has a chance against Kyrgios.
"A top 1,000 player, or someone who is not ranked, can beat a top ten player on the WTA tour. When I was at my best, a junior could beat me," she told Spanish radio station Cope.
To make the match a bit more balanced, Sunday's players will only get one serve. And Sabalenka's half of the court is nine percent smaller than Kyrgios'.
