Michael van Gerwen won his third PDC Unicorn Youth Tour title at the Moorways Centre, defeating Michael Smith 4-1 in the final.
The Dutch ace followed up victories in Wigan and Crawley earlier this year by taking the £600 first prize in Derby, courtesy of a brilliant showing in Event 11.
He whitewashed fellow countryman Jimmy Hendricks as well as Wales' Marc Evans in the early stages, and dropped only one leg against Leon Bailey and Ricky Evans in reaching the semis.
There, he overcame fellow countryman Rick Veugelers 4-1 and produced the same scoreline to win the final in style.
After Smith missed the bull for a 170 finish in the opening leg, van Gerwen took out double 16 to lead before opening the second with a 177.
Smith hit two 180s in reply, but the Dutchman denied him a dart at double 13 by finishing tops for an 11-dart leg to double his advantage.
The pair traded maximums in the fourth leg, which Smith won with a 90 finish, but tops gave van Gerwen a 3-1 lead before he repeated the double to secure victory.
Smith's display included victories over Welsh youngster Jamie Lewis, Holland's Mike Zuidwijk and former Youth Tour winner Paul Barham as well as whitewashes of Sam Davidson and Darren Whittingham.
The St Helens ace picked up £400 as runner-up, as he lost in the final for the second time this year after being in the decider in Event Two back in February, when he had also hit a nine-darter.
Lewis celebrated his third appearance on the Youth Tour by reaching the last four, where he was joined by Dutch youngster Veugelers - who had overcome compatriot Dirk van Duijvenbode in the last eight.
The next PDC Unicorn Youth Tour event will be held in Nuland on Saturday September 24, with entry available via the PDC Head Office on 08712 501 180 or via www.pdc-europe.net for non-UK & Ireland players.
