Co Stompe warmed up for his debut appearance at the Ladbrokes.com World Championship by claiming his first PDC title with a 4-2 victory over Phil Taylor in the final of the 2008 PartyPoker.net German Darts Championship.
The Dutchman came from 2-1 down to win three successive sets in a brilliant final - matching Taylor blow for blow, with both players averaging over 107.
Taylor hit a pair of 12-darters to take the first set, and an 11-darter to level in the next, but Stompe landed double ten in the second set's deciding leg to level.
The duo shared 180s in the third set's opener, which was won by Taylor with a 101 finish for a 12-darter, only for Stompe to better a 174 from the Englishman with a 177 in the next and then step in to land double top.
But Taylor took the set's deciding leg with a 13-darter for a 2-1 lead, which was once again pegged back when Stompe took an extraordinary fourth set.
Taylor landed three 140s in the opening leg, but a missed bullseye allowed Stompe in for a 14-darter, before the Dutch ace set up a potential nine-darter in the next leg with scores of 174 and 180.
He hit the treble 20 and treble 17 but wired the double 18, and Taylor - who had landed a maximum of his own in the leg - took out double seven.
Stompe landed another maximum in the deciding leg, which he won on double nine to square matters.
Taylor led in the fifth set, hitting a second 101 finish, with Stompe sat on 40 after setting up a double with a 177.
Stompe hit scores of 174 and 128 in the next leg, and a missed bullseye from Taylor let him in on double eight, before a missed double top from the world number one was punished by the Dutchman on double ten as he took the lead at 3-2.
A 105 checkout put Stompe in front in the next set, with Taylor kicking off leg two with a 180 but missing three darts at double top and ten before Stompe sealed a remarkable win on double 16.
Stompe ended the game with a superb 107.28 average, with Taylor averaging 108.09 in defeat - having been close to 120 for much of the first five sets.
"In all honesty I never expected to win the game because of the standard Phil has set," said Stompe, who overcame Steve Hine and Andy Hamilton on Sunday to reach the final.
"In many ways we come into events trying to be the 'best of the rest', and to give Phil a run for his money.
"Phil is the best darts player the planet has ever seen and normally has an answer to everything but I found some answers too.
"I've been European Champion and reached the semi-finals at Lakeside but this is the PDC, and beating Phil Taylor in the final is the greatest moment in my career, there's nothing better than that."
Taylor had not dropped a set in reaching the final, powering past Wayne Jones with a 112.98 average in the quarters and defeating World Champion John Part 4-0 in the semis.
"Obviously I'm gutted but I lost to a better player in the final," said Taylor. "I was over the moon just to be in the final and thought I was going to win it after my performances over the last couple of days.
"But I didn't win and Co played better than me to be honest.
"I think a lot of other players would have folded after the start I made in the final but he didn't. He was enjoying himself and played fantastically.
"I put a lot of darts on the wire and not in trebles and I was pushing to win sets and when he won the fifth set, that was a killer."
He added: "The defeat won't do me any harm and it's given me a big punch in the mouth. I'll be locking myself away and getting ready now for the World Championship."
