Coletta will improve to 22nd in the season-long standings as he chases a spot inside the top 25 who gain automatic graduation to next season’s PGA Tour.
Coletta birdied three of his last five holes for a round of 66 to improve from his overnight 9th, seemingly finding a form reversal in his last two weeks.
Sydney’s Jamie Arnold also tied for 4th and moved to the verge of a spot in the top 25 but he will rue a horror finish which included a double bogey at the 15th and a bogey at the 16th.
Arnold does however move from 42nd to 31st in the standings and with three more events remaining in the regular season ahead of the Korn Ferry Tour Finals, the NSW golfer has his chance to get to the PGA Tour for the first time.
Brett Drewitt was 18th and Rhein Gibson finished 27th.
Gibson - in 9th position in the standings - is assured of a return to the PGA Tour for the 2019/2020 season.
