Judd Trump was trembling with nerves as he clinched his place in the World Championship final but now insists he will take some stopping.

The 21-year-old qualifier, whose astounding impact in the past fortnight has seen him likened to Jimmy White and Alex Higgins, blazed to a 17-15 victory over China’s Ding Junhui yesterday to become the youngest finalist since Stephen Hendry in 1990.

He could pocket a £250,000 jackpot tomorrow evening, and quipped: “I’ll probably want a new car at the end of this – maybe a Ferrari or a Lamborghini.”

Trump came from 15-14 behind to beat Ding in one of the great Crucible semi-finals, finishing off with a sublime 105-break under pressure.

“It hasn’t sunk in yet. I’ll have to go away and have a little think about it,” Trump said.

“Towards the end I’ve never felt nerves like it. Even though the balls were all there, it hits you really. I just took my time and knew if I didn’t miss anything silly they were all there to be taken.

“I feel sorry for Ding because he couldn’t have played much better; if he’d have played anyone else then he would have probably won.”

Trump claimed after his win over Dott that he felt “invincible”, and the success against Ding has reinforced that view.

“Winning that game makes me feel more invincible than I was before,” he said.

Ding led the semi-final 15-14 after a break of 119 and held a 48-0 lead in the next frame. But the Chinese 24-year-old lost positioning, and Trump came back to take it, finishing off with a run from yellow to pink after laying a good safety which caused Ding to leave him a chance.

Ding had earlier rattled in 138, matching the highest break of this year’s tournament, set by Mark King against Graeme Dott in the first round. Unless that is bettered, Ding and King will share £10,000.

Other semi-final: Higgins bt Williams 17-14.
