Stefanos Tsitsipas

Stefanos Tsitsipas (Greek: Στέφανος Τσιτσιπάς, pronounced [ˈstefanos t͡sit͡siˈpas]; born 12 August 1998) is a Greek professional tennis player. He has been ranked as high as world No. 3 in men's singles by the Association of Tennis Professionals (ATP), first achieved in August 2021 – making him the highest-ranked Greek men's tennis player. Tsitsipas has won twelve ATP Tour singles titles, including the 2019 ATP Finals and three Masters 1000 events. He has contested two major finals, at the 2021 French Open and 2023 Australian Open. He has a career-high doubles ranking of No. 64, achieved on 29 August 2022.

Born into a tennis family – his mother Julia was a professional on the WTA Tour and his father Apostolos trained as a tennis coach – Tsitsipas was introduced to the sport at age three and began taking lessons at age six. As a junior, he was ranked No. 1 in the world, and won the 2016 Wimbledon boys' doubles event.

Winning his first match on the ATP Tour in late 2017, Tsitsipas quickly ascended the ATP rankings the following year. He won his first title at the 2018 Stockholm Open and made a runner-up finish at the 2018 Canadian Open, becoming the youngest player to defeat four top ten opponents in a single tournament at the latter event. After finishing that season with an exhibition title at the Next Gen ATP Finals, Tsitsipas remained an almost constant fixture in the top 10 of the ATP rankings until 2024. He won his first Masters 1000 event at the 2021 Monte-Carlo Masters, an event he won twice more in 2022 and 2024. Tsitsipas was named the Greek Male Athlete of the Year for 2019.
