History was on the line for Novak Djokovic at the 2021 U.S. Open, as the 34-year-old Serb was seeking his 21st major title—one that would snap a three-way tie with career-long rivals Roger Federer and Rafael Nadal—and the calendar Grand Slam. On Sunday, the historic achievement was thwarted by Russia's Daniil Medvedev in the final. But it should not be overlooked that Djokovic was attempting this incredible feat, all while leading a labor movement.
It was at the U.S. Open last summer that Djokovic and fellow player Vasek Pospisil officially announced the formation of the breakaway Professional Tennis Players Association (PTPA), targeting reforms such as increased prize money and greater transparency when it comes to revenue sharing.
