Luke Littler comfortably beat Michael Smith 11-4 to claim his maiden World Series of Darts Finals title in Amsterdam.
The teenager recovered from losing the opening two legs to race into a 7-3 lead by the interval.
Littler, 17, picked up where he left off after returning to the oche and averaged 102.21 on his way to victory and an £80,000 prize fund.
The Englishman also disposed of home favourite Michael van Gerwen 11-4 in the semi-final.
Littler, who began the day with a quarter-final victory over Chris Dobey, secures his third World Series title after previously winning in Bahrain and Poland this year.
He also won the Premier League Darts title in May after beating Luke Humphries to avenge his defeat in the final of the World Championship.
“I’m very happy to win. To come here and win on my debut is a good feeling.
“I’m playing well so I will go back home and practice even more. There is no time to sit about, it’s a busy winter coming up.
“Everyone wants to win everything but I’ve learned you can’t do that. I would like to win another major World Series of Darts Finals: Luke Littler beats Michael Smith to win third world series title. I want the Worlds as anyone else does but another major would mean the world.”
Asked if he is currently the best player in the world, Littler said: “Probably over this weekend.
“To average 103 over four or five matches, it has been really good and I’m proud of myself.”
