Kyren Wilson kept his nerve to beat Judd Trump 10-9 and claim the first ranking tournament title of his career at the Shanghai Masters.
The 23-year-old from Kettering produced a break of 75 in the deciding frame to secure a thrilling victory after Trump had won two frames in succession to level the match from 9-7 down.
Starting the week ranked 54 in the world, Wilson - who had never previously gone beyond the last eight in a ranking event - becomes the lowest-ranked player to win one since 2005.
Wilson started the final full of confidence after following up wins over Joe Perry, Michael Holt and Ding Junhui, followed by Saturday's 6-1 semi-final thrashing of Mark Allen.
The underdog won three frames in a row to take a 7-3 advantage but Trump was in no mood to give in as he searched for his first title since last year's Australian Goldfields Open.
A break of 115 reduced the deficit to 7-4 and though Wilson won the next with a 68, Trump came back to trail by only one frame at 8-7 and seemed to have the momentum.
After Wilson edged to within one frame of victory, an 89 from Trump made it 9-8 before he drew level in an edgy frame 18.
But showing the maturity which had carried him through the whole competition, Wilson seized on an early chance in the decider and was visibly emotional as he picked up the £85,000 prize.
