Cadby defeated former World Series qualifier Tic Bridge, Tim Pusey and finally a World Championship qualifier of recent times, Gordon Mathers to win event four.
The UK Open finalist also overcame his father Fred Cadby in the event on his way to the victory.
He then reached the semi-finals on Saturday losing to eventual winner Raymond Smith and then the Quarter-Finals on Sunday in an event Mal Cuming won.
It isn’t known when he will return to the tour over here in the UK but it is good news that the King is still on form when back home.
