Mark Walsh celebrated victory in a UK Open Qualifier in Derby for a second successive year with a 6-2 defeat of Phil Taylor in Sunday's final.
Walsh had defeated Raymond van Barneveld to take the £6,000 title at the Moorways Centre in 2009, and this time overcame the World Champion in the decider.
He had held off a Co Stompe fightback to win their semi-final 6-4, having led 3-0 and 4-1 before the Dutchman levelled.
Walsh also took some notable scalps in the early rounds with wins over Colin Lloyd, Mark Webster and Dennis Priestley, before seeing off Colin Monk 6-1 in the quarter-finals.
He saved perhaps his best form for the final, taking out double five for the opening leg after Taylor missed two darts to break throw, before finishing 100 in the second leg to move two legs up.
Taylor hit back with a 14-darter, but paid for missed doubles in the next two as Walsh took out a brace of 14-darters on 62 in reply to move 4-1 up.
Taylor hit a 177 score to lead 28 in taking leg six, but was waiting on 40 as Walsh landed a 14-dart finish to move a leg away from the win.
Taylor missed double top for a 104 finish in the next leg, and Walsh followed up a 177 to leave 40 by hitting the bed for a 13-dart finish in celebrating the victory.
"I must love this venue and it's a great confidence boost for me," said Walsh. "I've had a bad six months or so but I think my game is coming together again.
"Defeating Phil at any time is memorable but to do so in a final is very special. Hopefully I can build on this now and have a good year."
Taylor had dropped only six legs in seven matches in taking victory in Saturday's Players Championship, and was in fine form again 24 hours later.
Only Andy Callaby won more than one leg against Taylor in his run to the final, losing 6-3 in round two, as Andy Hutchings, Kevin Painter, Nick Fullwell, Jelle Klaasen and Andy Hamilton lost 6-1.
World number three James Wade reached the last eight, including wins over Paul Nicholson, Andy Smith and Wayne Mardle to warm up for Thursday's Whyte & Mackay Premier League Darts clash with Adrian Lewis in Exeter.
Lewis also won through to the quarters before losing to Hamilton, while Monk's run to the last eight was his best showing since October.
