Jannik Sinner (Italian pronunciation: [ˈjannik ˈsinner]; German pronunciation: [ˈjanɪk ˈzɪnɐ]; born 16 August 2001) is an Italian professional tennis player. He has been ranked as high as world No. 9 by the Association of Tennis Professionals (ATP), achieved on 1 November 2021, and world No. 124 in doubles, achieved on 27 September 2021. Sinner has won seven ATP titles in singles and one in doubles, and became the youngest ATP title-holder since 2008 by winning the 2020 Sofia Open and the youngest to have five titles since Novak Djokovic in 2007. He became the first teenage ATP 500 champion since the category was renamed in 2009 by winning the 2021 Citi Open.
Sinner grew up in northern Italy in the region of South Tyrol. He was active in skiing, football, and tennis as a child. After winning a national championship in skiing at age eight, Sinner switched his focus to tennis at age thirteen and moved to the Italian Riviera to train with veteran coach Riccardo Piatti. Despite limited success as a junior, Sinner began playing in professional events at age 16 and became one of the few players to win multiple ATP Challenger Tour titles at age 17. He won the ATP Newcomer of the Year award in 2019 after breaking through into the top 100, reaching his first ATP semifinal, and winning the Next Generation ATP Finals in Milan.
Sinner continued his rise into the top 50 in 2020 with his first top 10 victories, a French Open quarterfinal (becoming the youngest quarterfinalist in men's singles since Novak Djokovic in 2006), and a maiden ATP title. He had a strong start to 2021, highlighted by his second ATP title in a row and a Masters 1000 runner-up at the Miami Open. On 1 November 2021, he became the first player born in the 2000s to enter the ATP top 10.
Sinner has an excellent two-handed backhand and has led the ATP Tour in the amount of topspin on the shot.
