Ronald Antonio O’Sullivan is an English professional snooker player. He is one of the most successful players in the sport’s modern era. He is regarded by many commentators as the most naturally gifted player in snooker history, and is frequently described as a genius. He is also noted for his mercurial temperament and for his ambivalent relationship with the sport, from which he has repeatedly threatened to retire. He made his first century break at the age of 10.
His first maximum break came at age 15. He turned professional in 1992 and soon earned the nickname The Rocket because of his rapid playing style. He achieved his first major professional success when he won the 1993 UK Championship at the age of 17 years and 358 days, making him the youngest player ever to win a ranking title. He is also the youngest player to have won the Masters. He holds the record for the most competitive century breaks, with 807. He also holds the record for the most ratified maximum breaks in professional competition and for the three fastest competitive maximum breaks, the quickest in 5 minutes and 20 seconds.
