At the UK Championship later that year, Magure defeated Mark King, Mark Davis, Stephen Lee, Ronnie O'Sullivan and Steve Davis "en route" to the final. In the final, Maguire defeated David Gray 10–1. Players praised the quality of the play Maguire had produced to win one of the Triple Crown events. Steve Davis described him as "inspired", while O'Sullivan suggested that "he could rule the game for the next ten years". At the 2005 World Snooker Championship first-round match, Magure led O'Sullivan 9–7 but lost 9–10. At the end of the season he moved from number 24 to third in the world rankings.
