Michael van Gerwen staged a remarkable comeback to beat Mervyn King and win the World Grand Prix title in Dublin.
The Dutchman, 23, trailed 4-1 in the best-of-11-sets final, but won five consecutive sets to win 6-4 and claim a winner's cheque for £100,000.
"It's the best day of my life," said van Gerwen, who moves up to eighth in the PDC Order of Merit.
"I'm not a person who gives up so this feels very good for me. I'm so happy to have won."
He added: "I started the year as the number 38 in the world and now I'm number eight, so it's unbelievable for me.
"I need to work on this and get more consistency. I've got a lot of work to do in the next couple of months but now I know what I feels like to win a major tournament like this. It's the best thing in the world."
