Unheralded Dutchman Christian Kist secured his first BDO World title as he saw off favourite Tony O'Shea 7-5 at Frimley Green.
The 25-year-old, who is a road worker by trade, had to qualify for the tournament via a play-off but has not looked back since, and followed up yesterday's semi-final win over Ted Hankey with another notable scalp.
He had been cruising towards the trophy when he moved into a seemingly unassailable 6-2 lead over the Englishman, but his veteran opponent finally found some form and moved back to 6-5.
Crucially for Kist, though, he took the first leg of the 12th set and, when O'Shea miscounted while trying to check out on 112, he took the second as well.
He then missed an attempt at double 16 to win it but, after O'Shea failed on double 14, he returned to land his dart in its intended target and kick-off the celebrations and take the £100,000 prize.
"I was 6-2 in front and there was no problem and then Tony came back and the nerves came," Kist told BBC Sport afterwards.
