Ronnie O'Sullivan rockets into snooker World Championship final after beating Judd Trump at Crucible Armed with a 14-10 lead heading into the fourth session of their semi-final, the defending champion punished Trump's errors to move a frame away from victory, with a flicker of a recovery from the young pretender extinguished as O'Sullivan came through a 17-11 winner. He has already claimed this will be his last appearance at the World Championship, where he has won all four of the previous finals he has contested, and given the ease with which he has carved a path through to the title decider, that can only be good news for his rivals, including the inconsistent Trump. Trump crashed in a 77 break to give himself the slightest hope, but the reprieve was all too brief as O'Sullivan creamed off breaks of 31 and 33 in the next frame to clinch a showdown with either Ricky Walden or Barry Hawkins in the two-day final, beginning tomorrow. Trump said of his performance: "I feel disappointment really because I did have chances and in the first two sessions I really struggled. As soon as he got in front he was so difficult to peg back. My scoring wasn't good enough at this level and it was the worst I've played in this tournament. He scored a lot heavier than I did. You've got to score while you're in. I probably got in first more than he did which showed how good my safety was. But over the tournament he has missed less easy balls than the rest of us. Trump urged O'Sullivan to reconsider his plans to walk away from snooker. "Hopefully next year he plays in it again so I can beat him," Trump added. I want to win the World Championship with him in it and I want to beat him on the way.
