World Champion Raymond van Barneveld suffered his second defeat of the 2007 Holsten Premier League Darts, with Dennis Priestley taking out the Dutchman 8-4 in Blackpool.
Van Barneveld bounced back from a defeat to Phil Taylor with a superb 8-1 win over Roland Scholten a week ago, but never settled against Priestley.
The 56-year-old Yorkshireman regained his finishing touch following his first defeat of the competition in Aberdeen seven days earlier to take a notable scalp.
Having previously drawn with Phil Taylor, Priestley moved onto 11 points and a step closer to securing his play-off berth with a famous triumph.
The opening four legs went with the throw before Priestley took out a crucial 124 finish on double 11 in leg five to break the throw - after van Barneveld leg 61 with a maximum.
Dennis PriestleyVan Barneveld saw the chance to break back in the next leg evaporate when he missed double 18, with Priestley landing a tricky double 19 to go into the break 4-2 up.
The Dutchman hit back with a 15-darter but a 120 "Shanghai" finish and then double five against the throw put Priestley 6-3 up.
The tenth leg proved pivotal in the outcome of the match, with a van Barneveld 180 leaving him 76 and Priestley's 177 setting up a 42 finish - only for both to suffer double trouble.
The Dutchman eventually missed nine darts at the double before Priestley one a double one shoot-out to ensure at least a draw.
Van Barneveld stayed in the hunt with a 64 finish, but wasted three darts at the double in leg 12 before Priestley took out double ten for the win.
"I'm obviously delighted to get the win but I didn't feel I played all that well," said Priestley. "It was a real contrast from last week, when I scored well but couldn't finish.
"I kept my nerves intact this week and it is such a big thing for us each week to get the two points.
"Perhaps I've been lucky but I'll take it!"
