Who dated Anna Kalinskaya?

Jannik Sinner (born 16 August 2001) is an Italian professional tennis player. He has been ranked world No. 1 in men's singles by the Association of Tennis Professionals (ATP), including as the year-end No. 1 in 2024. Sinner has won 20 ATP Tour–level singles titles, including four majors: two at the Australian Open, one at the Wimbledon Championships, and one at the US Open. He has also won the 2024 ATP Finals, and led Italy to the 2023 and 2024 Davis Cup crowns.

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 Generation 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 Masters 1000 title at the 2023 Canadian Open and finished that season by reaching the final of the ATP Finals and leading Italy to the Davis Cup crown.

At the 2024 Australian Open, Sinner defeated world No. 1 Novak Djokovic and then Daniil Medvedev in a five-set final to win his first major title. He followed by winning three Masters 1000 events, the US Open, and the ATP Finals to finish the year as the world No. 1, the first Italian to reach the top ranking. In 2025, Sinner defended his title at the Australian Open and, following a three-month suspension for the accidental administration of clostebol, finished runner-up at the French Open, losing an epic final to his career rival Carlos Alcaraz. He rebounded by winning Wimbledon over Alcaraz in the final, becoming the first Italian to win the title.
