Template - Date: Development Tour Weekend

MIKE DE DECKER won his third PDC Unicorn Development Tour title with a narrow 4-3 victory over Berry van Peer in the final of Event 19 as the 2016 season came to a close in Wigan.

Belgian ace De Decker, a 20-year-old from Mechelen won two Development Tour events in 2015, and capped this year’s campaign by winning the £2,000 first prize in Sunday’s event.

Following a narrow 4-3 win in his opener against Cas Hogenhout, De Decker dropped just two legs in his next four games as he overcame Shane Reidy, Carlo van Peer, Russia’s Anton Kolesov and Denmark’s Daniel Jensen.

He then edged out former World Youth Champion James Hubbard in the semi-finals before repeating the 4-3 scoreline in the final against Berry van Peer, completing a double over the Dutch brothers in the tournament.

Berry van Peer, 20, had won two titles himself in 2015 and followed up three previous semi-finals this year with his best display of the year to reach the Event 19 final.

In a tough route through the event, van Peer dropped only one leg in his early wins over Ryan McCarthy and Ryan Meikle before edging out Callan Rydz – a semi-finalist in both of Saturday’s events – before seeing off Ryan De Vreede, Kurt Parry and Aden Kirk on his way to the decider.

Norfolk’s James Hubbard was a semi-finalist for the second time this year, while Aden Kirk was bidding to win his third Development Tour title as he also won through to the last four.

Danish youngster Jensen warmed up for his challenge at the PDC Unicorn World Youth Championship by reaching the quarter-finals alongside Justin Smith, Callum Loose and Welsh ace Parry.

In total, 252 players earned prize money on the PDC Unicorn Development Tour in 2016, with 19 events being held across the UK and in Germany during five weekends.

The season concludes on Sunday afternoon with the Last 64 of the PDC Unicorn World Youth Championship, with qualifiers fro the Development Tour Order of Merit joined by a series of International Qualifiers and two Junior Darts Corporation representatives.

Dean Reynolds’ win in Event 17 on Saturday secured him the top place on the Development Tour Order of Merit, with Ross Twell finishing second to join him in securing a PDC Tour Card for 2017/2018.

In addition, the players finishing from third to eighth will earn free entry to the 2017 PDC Qualifying School (if they do not already possess a PDC Tour Card).


Dean Reynolds was confirmed as the DTOoM Table winner with Ross Twell the Runner-Up and both players are offered a 2 year PDXC Tour Card.
