Sofia Kenin

Sofia Anna "Sonya" Kenin (born November 14, 1998) is a Russian-born American professional tennis player. She has been ranked as high as world No. 4 in singles by the WTA, and No. 21 in doubles. Kenin was named the 2020 WTA Player of the Year, an award earned by winning the Australian Open and finishing runner-up at the French Open. She has won five singles and four doubles titles on the WTA Tour, the latter including the 2019 China Open and 2024 Miami Open partnering Bethanie Mattek-Sands.

Coached primarily by her father, Kenin developed into a promising junior player, reaching No. 2 in the world after winning the Orange Bowl at the age of 16 and finishing runner-up in the 2015 US Open girls' singles event the following year. She also won the USTA Girls 18s National Championship during that summer. Kenin made her debut in the top 100 of the WTA rankings in 2018 as a teenager. She won her first three titles in 2019 and finished the year just outside the top 10, being named the WTA Most Improved Player of the Year. With her title at the 2020 Australian Open, Kenin became American No. 1 and the youngest American to win a Grand Slam women's singles title since Serena Williams in 1999.

Sofia Kenin was born as Sofia Aleksandrovna Kenina in Moscow, Russia, to Alexander Kenin and Svetlana Kenina. Kenin is Jewish, and was born in a Jewish family, and has a younger sister. Her family moved to the United States a few months after she was born. They had previously left the Soviet Union to live in New York City in 1987 but returned to Russia for Kenin's birth so that other family members could help raise her initially. Her mother had worked as a nurse in the Soviet Union, and her parents had only $286 when they first moved to the United States.
