Passage: As an amateur, Doherty won the Irish Amateur Championship twice, the World Under-21 Amateur Championship and the World Amateur Championship. Having turned professional in 1990, Doherty has won a total of six ranking tournaments, including the 1997 World Snooker Championship in which he defeated Stephen Hendry, inflicting Hendry's first loss in a world final.

He reached a third final in 2003, in which he was defeated by Mark Williams. In other triple crown events, he is a three-time UK Championship runner-up and a two-time Masters runner-up.
