Frances Tiafoe Jr. ( tee-AH-foh; born January 20, 1998) is an American professional tennis player. He reached his career high at world No. 10 in singles on June 19, 2023, becoming the first Sierra Leonean American man to be ranked in the top 10 by the ATP.
Tiafoe won his first of three ATP titles at the 2018 Delray Beach Open, becoming the youngest American man to win a tournament on the ATP Tour since Andy Roddick in 2002. He won his second title on clay at the 2023 U.S. Men's Clay Court Championships in Houston and his third on grass in 2023 Stuttgart. He also has a career-high ranking of No. 160 in doubles on November 1, 2021.
The son of Sierra Leonean immigrants, Tiafoe was raised at the Junior Tennis Champions Center (JTCC), a USTA regional training center in College Park, Maryland, where his father worked as the head of maintenance. His unique background and success as a teenager led him to be widely regarded as a great prospect to become one of the next American tennis stars. At 15, Tiafoe won the 2013 Orange Bowl, the tournament's youngest-ever boys' singles champion. At 17, he became the youngest American in the main draw of the French Open since Michael Chang in 1989. As a teenager, he won the US Junior National Championship and enjoyed success on the ATP Challenger Tour, reaching nine finals and winning four titles.
Tiafoe broke into the top 100 of the ATP rankings in 2016. At the 2019 Australian Open, he reached the quarterfinals, and at the 2022 US Open, he reached the semifinals of a Grand Slam tournament for the first time.
