Ireland's Keane Barry is now a dual darts world champion after winning the BDO World Youths Championship in London.
Barry picked up the Junior Darts Corporation's world title at Alexandra Palace last month, a few days after making his debut in the senior PDC World Championship at the same venue.
The 17-year-old from Meath saw off defending champion Leighton Bennett at the O2 this afternoon.
Bennett, 14, had himself made his senior world championship debut earlier this week when he lost out to Scott Mitchell in the British Darts Organisation's premier event.
The 3-0 win, where he averaged 90.54 and hit three 180s in a mature performance, means Duleek's Barry, who is the current Irish Matchplay champion, now holds the BDO's Boys Youths World Masters, JDC and BDO world titles.
Next on the agenda for Barry, known as 'Dynamite', is an attempt to gain a full PDC tour card at Q School in Wigan from 16-19 January.
He will also face Luke Littler in the JDC Super 16 academy final, which will be held during the World Masters at Milton Keynes on 2 February.
"This year has gone really well for me, 2019 was good and I'm after starting off 2020 with a very good win," he told Eurosport.
"Leighton Bennett was unbelievable, he's on this stage for a reason, he's deserves everyone's applause.
"I'm over the moon to win this. I'm aiming to reach the top, but you have to take every game as it comes and every year as it comes.
"I'm going to get my head down, I've Q School next week and we'll see what that brings. I'm looking forward to the year ahead."
