Adam Hunt won the inaugural PDC Unicorn Youth Tour event, overcoming Josh Jones 4-2 in the final at Derby's Moorways Leisure Centre.
Chester-le-Street's Hunt, 18, picked up the £600 first prize in the first of 15 events to be held this year for players aged from 14-21.
The youngster had competed earlier on Saturday in the Players Championship in Derby, overcoming experienced professional Andy Smith 6-5 in the first round before losing out to Chris Aubrey.
However, he fared even better in the PDC Unicorn Youth Tour event, whitewashing Sean White and Marc Evans before then defeating Josh McCarthy 3-1 and Jamie Green 3-2.
He then overcame Birmingham's Matt Gallett 3-0 in the quarter-finals and defeated Kettering's Ricky Evans 4-1 in the semis.
Hunt shared the first four legs of the final with Jones, but punished missed doubles from the 20-year-old from Rugby in the next two to secure victory.
Jones, who turns 21 on Sunday, was denied the perfect birthday present but still pocketed £400 for reaching the final.
He had defeated Tunstall's Jamie Landon 4-1 in the semi-finals, whitewashed Sunbury-on-Thames' Brandon Monk in the quarters and also knocked out Chris Aubrey and Dutch talent Jimmy Hendriks in the event.
Adam Smith-Neale, who won a PDC ProTour Card this year and has already competed three times on the professional circuit, reached the last eight before losing to Landon, while Newbury's Jonathan Mulley was the other quarter-finalist.
PDC Unicorn Under-21 World Champion Arron Monk lost in the last 32 to Darren Whittingham, while Co Stompe Jnr - the son of the Dutch ace - was defeated in round one by Tom Murray.
The second PDC Unicorn Youth Tour event will be held at the Barnsley Metrodome next Saturday, with 110 players already entered for the £2,000 tournament.
