In the World Championship, Higgins defeated Stephen Lee 10–5 in the first round, Rory McLeod 13–7 in the second round and Ronnie O'Sullivan 13–10 in the quarter-finals. On the way to a 17–14 victory over Mark Williams in the semi-finals, Higgins was heckled by an audience member who shouted out, "How do you swallow that three hundred thousand, John? ... You're a disgrace to snooker." Higgins went on to defeat Judd Trump 18–15 in the final to win his fourth world title, which prompted Steve Davis to comment "I think John Higgins is the best snooker player I've ever seen in my life". Despite the victory, Higgins lost the world number one ranking to Mark Williams.
