Jannik Sinner (born 16 August 2001) is an Italian professional tennis player. He is currently ranked world No.1 by Association of Tennis Professionals (ATP), and was the year-end No. 1 in 2024. Sinner has won 29 ATP Tour–level singles titles, including four majors, ten Masters 1000 events, and two ATP Finals titles. He also led Italy to back-to-back Davis Cup crowns in 2023 and 2024. Sinner is one of two men (and the youngest) to complete the career Golden Masters in singles.

At age 13, Sinner moved to Bordighera to join the Piatti Tennis Center. Despite limited success as a junior, Sinner began playing in professional men's events aged 16 and became one of the few players to win multiple ATP Challenger Tour titles at age 17. In 2019, he won the Next Gen ATP Finals and the ATP Newcomer of the Year award, and two years later became the first player born in the 2000s to enter the top 10 in rankings. Sinner won his first ATP Masters 1000 title at the 2023 Canadian Open and finished the season as runner-up at the ATP Finals. At the 2024 Australian Open, Sinner defeated world No. 1 Novak Djokovic followed by Daniil Medvedev in a five-set final to win his first major title. He went on to win both the US Open and the ATP Finals to finish the year at the top of the ATP rankings, becoming the first Italian player to reach world No. 1.
