Mike De Decker produced the performance of his life to claim BoyleSports World Grand Prix glory on Sunday night, defeating Luke Humphries 6-4 in sets at Leicester's Mattioli Arena.
The 28-year-old from Belgium had won through to his maiden televised final with a series of superb displays in the double-start tournament, and scooped the £120,000 top prize following a thrilling final.
Reigning champion Humphries was left reeling as De Decker came from a set down to lead 4-1 with a brilliant and nerveless burst.
The world number one hit back with three straight sets to level, but De Decker took set nine before closing out victory in the deciding leg of set ten.
De Decker's success makes him only the second Belgian - alongside Dimitri Van den Bergh - to taste victory in a televised PDC event, and catapults him from 36th to 25th on the PDC Order of Merit.
