DIMITRI VAN DEN BERGH and Mike Van Duivenbode continued their success on the PDC Unicorn Development Tour as they claimed victories on Saturday's double-header at the Barnsley Metrodome.
The fourth of five Development Tour weekends of the year began as Belgian ace Van den Bergh claimed his third title of 2017 with victory in Event 13.
The Belgian ace has previously won nine events since 2013 on the PDC's youth system, and moved into double figures as he defeated Griffin in a deciding leg in the final.
After opening Event 13 with 4-1 wins over Scott Dale and Dawson Murschell, he overcame Adam Smith-Neale 4-2 and then dropped just leg in defeating George Andrew to reach the last eight.
There, he saw off Justin Smith 5-3 before repeating that scoreline in the semi-finals against Adam Hunt, and although Griffin shared the final's opening eight legs it was Van den Bergh who claimed the deciding leg and the £2,000 first prize.
Griffin won through to his first Development Tour final since 2015 as he defeated Luke Nelson, Jack Vincent, Ronnie Roberts, Berry van Peer, Luke Humphries and Harry Ward.
Van den Bergh was within touching distance of a daily double as he won through to the Event 14 final against Van Duivenbode, only for the Dutchman to take a 5-3 win in the decider as he claimed his second title of the year.
Van Duivenbode defeated Dylan Powell, Sean Johnson, Rob Hewson and William Borland for the loss of only four legs as he reached the quarter-finals.
He then defeated fellow countryman Justin van Tergouw 5-2 in the last eight and saw off Austrian ace Rowby-John Rodriguez 5-3 to reach the final, where he repeated the scoreline to take the £2,000 top prize.
Van den Bergh saw off Rusty-Jake Rodriguez, George Killington, Rhys Hayden, Ryan Meikle, Adam Hunt and Christian Bunse as he claimed a spot in a second final of the day during a memorable run of form.
German youngster Bunse joined Rowby-John Rodriguez in the last four, while Hunt, Van Tergouw, Sven Groen and Berry van Peer completed a cosmopolitan line-up in the last eight.
Sunday sees Event 15 and Event 16 complete the Development Tour double-header weekend in Barnsley, with a further £20,000 in prize money on offer.
