Gary Anderson beat 16-time champion Phil Taylor 7-6 in a thrilling final to win his first PDC World Championship.
Taylor fought back from 3-1 and 6-4 down to level at 6-6 at Alexandra Palace.
Anderson, 44, won the first leg of the decider and when Taylor missed double 12 in the next, the Scottish fourth seed capitalised.
"Phil is the best and always will be the best so that makes it more special," Anderson told Sky Sports.
"I went 6-4 up and then after the break Phil took the next two sets and I felt it was gone."
Englishman Taylor, who failed to win a 17th world title, said: "Doubles cost me a couple of sets and he took advantage.
"My double eight and 16 were awful but Gary put me under pressure.
"At 6-6 I felt I had him and my energy levels were good. but he did a job on me and he beat me up in the last set."

Anderson became the first Scot to win a world title since Les Wallace claimed the BDO crown in 1997.
A 121 checkout gave Anderson the first set before a missed double 10 allowed Taylor to level.
Despite losing the next two sets, a run of nine legs out of a possible 10 saw Taylor open up a 4-3 lead.
Anderson missed bullseye for an 85 finish in the next set but Taylor missed 24 and allowed Anderson to level the match.
In the ninth set, Anderson failed to score on his first visit to the board after his third dart knocked out the previous two.
Visibly annoyed, he lost the first two legs, but regrouped to win the next three and, then opened up a 6-4 lead by taking the next set.
Taylor almost completed a nine-dart finish at the start of an 11th set he won 3-0, and won the decisive fifth leg in the following set to level the match at 6-6.
Three missed Taylor double 16s allowed Anderson to take a 2-0 lead in the final set and, although he missed a bullseye for victory, a double 12 completed a remarkable win.
