Serena Williams reads a reimagined version of Rudyard Kipling's poem ‘If'

The era is almost over.

One of the greatest tennis players of all time, Serena Williams, is set to retire.

It's hard to imagine tennis without the American legend who has won everything there is to win.

Williams will be remembered as one of the game's greatest competitors and an athlete who possessed the purest serve in the women's game.

She will be remembered for speaking out against racism, pushing for gender parity and equal prize money, as well as her experiences as a black woman.

World number 11 Coco Gauff said that Serena Williams was the reason why she plays tennis and that her legacy can inspire many more generations.

Gauff said that tennis was a mostly white sport. Someone who looked like me dominated the game. I believed I could dominate as well.
