Masters champion and world number two Adam Scott clinched a four-shot victory at the Australian PGA Championship following a final-day 67.

The home favourite carded three birdies and an eagle while dropping just the one shot on the par-four ninth as he went round in four under par on a rain-affected last day.

That left the Adelaide-born 33-year-old on 14 under for the tournament at Royal Pines on the Gold Coast, and saw him claim victory ahead of American Rickie Fowler.

Fowler, who led by two shots after the first round following his course-record 63, scored 68 on Sunday to finish on a 10-under total of 274 at the joint PGA Tour of Australasia/OneAsia Tour tournament.

Victorian trainee Jack Wilson (68) was third on eight under while his compatriot Cameron Percy (68) was a shot further back in fourth.

David McKenzie, who had been joint second alongside Fowler overnight, three shots behind leader Scott, fared poorly on the last day as his 74 left him tied for 11th place on four under par.

Play had been suspended for 90 minutes at one stage because of bad weather.
