World No. 3 tennis star Coco Gauff won the 2024 WTA Finals on Saturday, becoming the youngest US player to take the tournament since Serena Williams in 2001.

Gauff's championship came by way of a grueling three-hour 3-6, 6-4, 7-6 (2) final match win over reigning Olympic champion Zheng Qinwen.

The 20-year-old's road to the $4.8 million purse — the largest in women's tennis history — included just her second-ever win over No. 2 Iga Świątek in the group round and a semifinal victory over No. 1 Aryna Sabalenka on Friday.

A winning end to a rollercoaster season

When asked about her 2024 season, Gauff told reporters, "There’s been a lot of ups and downs. At moments, it felt great. At other moments, it felt awful. Basically, a typical year on tour."

Her low point was a disappointing attempt to defend her 2023 US Open title. Gauff stumbled out of the US Grand Slam in the fourth round this fall.

That performance led Gauff to an apparently productive coaching change. She left coach Brad Gilbert, adding Matt Daly to her team to work with Jean-Christophe “JC” Faurel.

Since then, Gauff has gone 13-2, ultimately adding the China Open and WTA Finals titles to her June French Open doubles trophy.

After silencing doubters with Saturday's victory, Gauff took to social media, writing "lol safe to say I beat the bad season allegations."

A double dose of WTA Finals history

Just before Gauff took the court, Canadian Gabriela Dabrowski and New Zealand's Erin Routliffe were crowned the season's doubles champions.

Dabrowski and Routliffe avenged their Wimbledon final loss by defeating US player Taylor Townsend and her Czech partner Kateřina Siniaková 7-5, 6-3 on Saturday. They are now the first athletes from Canada and New Zealand to win the WTA Finals doubles title.
