The Rocket, who came out a 17-11 winner against the world number three, is now one win away from his fifth world title and becoming the first player to defend the World Championship crown since 1996 when Stephen Hendry claimed his sixth world title after beating Peter Ebdon.
O’Sullivan’s run to the final in this year’s World Championship is something of a remarkable achievement considering his break away from sport lasting almost a year and having played just one competitive game all season.
And he will go into the final with the stunning statistic of never being behind throughout the tournament – no player in history has won snooker’s biggest prize without being behind.
Leading 14-10 overnight in a match which failed to live up to its hype, O’Sullivan made all but certain of reaching his fifth career World Championship final when he quickly wrapped up the first two frames of the session to go 16-10 ahead.
Trump pulled a frame back with a break of 77 but there was no stopping O’Sullivan in the next frame when runs of 31 and 33 confirmed his victory. He will play either Ricky Walden or Barry Hawkins in the final – in a match will undoubtedly see the four-times world champion as a huge favourite.
“It was tough because I don’t think either of us played anywhere near our best,” O’Sullivan said.
“There was a lot of tension out there during the sessions. We practise in the same environment and used to have the same manager so obviously that creates a derby match feel.
“Then you have the crowd who are excited by the way Judd plays and over the years I’ve also had such great support. Everyone was really geared up for it with the newcomer and the future of the game against someone who’s been around for a long time and wears his heart on his sleeve.
“I might say some things that frustrate people sometimes but my fans always get behind me because they know I try my hardest and give it my best every time I go out there.”
