Judd Trump laid his hands on the williamhill.com UK Championship trophy after beating Mark Allen 10-8 in a gripping final in York.
The 22-year-old from Bristol caused a sensation at this year's World Championship when, as a qualifier, he sprung shock result after shock result before losing out to John Higgins for the title.
And Trump was not to be denied on another big stage, adding the UK crown to the China Open success he achieved just prior to heading to the Crucible in April.
Trump fended off a sparkling evening revival from Allen, who rifled three century breaks in four frames, to win 10-8 and carry off the silverware and a cheque for £100,000.
"To win it the way I did is a brilliant achievement," Trump said.
"Mark pushed me all the way. It's a good job I had a big lead in that last session."
The handsome prize pot takes the new champion's earnings for the year above £350,000.
The Barbican Centre crowd were wowed by a match-defining run from Trump of seven frames in a row which took him from 3-1 behind to 8-3 ahead and left Allen with too much ground to make up.
Allen went close to pulling off the spectacular comeback but he rattled a long red in the jaws of a corner pocket at the start of frame 18 and Trump, having spent so much of the evening in his chair, seized his big chance with a rapid match-clinching 91 break.
It was a reminder of the "naughty" snooker Trump spoke of over the past week, the brand which has turned him from a precocious youngster to the most exciting player in the game just now.
