Ronnie O'Sullivan

Ronald Antonio O'Sullivan (born 5 December 1975) is an English professional snooker player. Widely recognised as one of the most talented and accomplished players in snooker history, he has won the World Snooker Championship seven times, a modern-era record he holds jointly with Stephen Hendry. He has also won a record eight Masters titles and a record eight UK Championship titles for a total of 23 Triple Crown titles, the most achieved by any player. He holds the record for the most ranking titles, with 41, and he has been ranked world number one on five occasions throughout his career.

After winning amateur titles including the IBSF World Under-21 Snooker Championship, O'Sullivan turned professional in 1992, aged 16. He won his first ranking event at the 1993 UK Championship and remains the youngest player to win a ranking title. He is also the youngest player to win the Masters, having claimed his first title in 1995. Now also noted for his longevity in the sport, he is the oldest winner of all three Triple Crown events.

O'Sullivan made his first competitive century break at age 10 and his first competitive maximum break at age 15. He was the first player to achieve 1,000 century breaks in professional competition, which he has since extended to over 1,300 centuries. He has made the highest number of officially recognised maximum breaks in professional competition, with 17, and holds the Guinness World Record for the fastest competitive maximum break, compiled in a time of 5 minutes and 8 seconds at the 1997 World Championship. At the 2026 World Open, he made the highest break in professional snooker history, a 16-red clearance of 153.
