The two-time World Champion opened his challenge in Sydney with a whitewash of David Clegg and a 6-3 win over Heath Daley before edging out Steve Hine in a deciding leg in the last 16.
He then overcame top Australian Simon Whitlock 6-3 in the quarter-finals and edged out Paul Nicholson – last year’s Australian Open Players Championship winner – in another 11-leg tussle at the semi-final stage.
Priestley secured victory in the final with a 6-3 win over Mark Hylton, the Rugeley-based left-hander who had won through to his first PDC ProTour decider.
Hylton opened with wins over Australian pair Pat Orreal and Peter Asmussen, and then battled through a tricky path to the final – picking up wins over Robert Thornton and Mark Walsh before edging out Sean Reed 6-5 in the semis.
Although he went down in the final, Hylton’s run will almost certainly win him a Ladbrokes.com World Darts Championship debut as a Players Championship Order of Merit qualifier, as well as increasing his hopes of winning a World Grand Prix spot.
Reed – who sits in the top ten of the DartPlayers Australia Order of Merit this year – claimed £1,250 for his run to the semis, which was begun with a first round defeat of former World Champion Steve Beaton and also included wins over Barry Jouannet and Preston Ridd.
Nicholson’s bid to retain the title came unstuck in the last four, after had had overcome current DPA Order of Merit leader Rob Modra in the quarter-finals.
Welshman Mark Webster joined Beaton in being a first round casualty, losing 6-4 to Mick McCreadie, while Tony Eccles and Richie Burnett went out in the last 32.
Former PDC player David Platt, who emigrated to Australia last year, reached the last 16 before losing to Whitlock.
The £22,000 Players Championship was the culmination of over a series of events in Australia, with Whitlock winning last Sunday’s Oceanic Masters and Thornton and Eccles taking Australian Grand Prix wins.
