Keane Barry will become the third youngest player to compete in the William Hill World Darts Championship when he steps out at Alexandra Palace against Vincent van der Voort.
Barry secured his place in the World Championship by winning the Tom Kirby Memorial Irish Matchplay final against Liam Gallagher in October.
He has drawn experienced Dutchman Van der Voort in round one, and will be 17 years and 174 days old when they meet on Monday December 16 - making him the third youngest player in the tournament's history.
Mitchell Clegg is the youngest player to have competed in the tournament, having been aged just 16 years and 37 days when he met Raymond van Barneveld in the first round in 2006/2007.
The second youngest player is Max Hopp, who was 16 years and 117 days old when he competed in 2012/2013, defeating South Africa's Charl Pietersen in the preliminary round before losing out 3-2 to Denis Ovens in round one.
Michael van Gerwen was previously the third youngest player, having been 18 years and 237 days old when he took on Phil Taylor in the 2007/2008 first round.
Barry is guaranteed at least two appearances on the Alexandra Palace stage, having also won through to the JDC's Scott Farms International Junior World Championship final, where he will take on Adam Gawlas on Saturday December 21.
The 2019/2020 World Darts Championship will be held from December 13-January 1 at Alexandra Palace in London.
The tournament will be broadcast live on Sky Sports in the UK, on PDCTV-HD for Rest of the World Subscribers and through the PDC's worldwide broadcast partners including DAZN and RTL7.
