Roommates Brett Coletta and Cameron Davis have set the stage for an all-Australian final-day shootout for the Asia-Pacific Amateur golf title, with a ticket to next year's US Masters awaiting the winner.
Victorian Coletta opened up a two stroke lead after three rounds at the Jack Nicklaus Golf Club in Korea, with his third-round four-under 68 leaving him at 14 under entering the final round.
Davis, who is sharing a room with Coletta at the event, had a 69 to be at 12 under overall, the Aussie pair well clear of Japan's Junya Kameshiro who is in third place at eight under.
Perth's Curtis Luck, who has already booked his ticket to Augusta next year courtesy of his 2016 US Amatuer title win, was next best at seven under, seven shots off the pace.
Starting the day with a one shot lead, Coletta raced out of the blocks with back-to-back birdies on holes number two and three.
Another pair of birdies had Coletta at four under through seven holes, and while he gave shots back with bogeys at No.8 and No.16, he finished strongly with another pair of birdies.
"You just have to put it down to the best on the day wins," Coletta said of the final-day shootout.
"There's no grudge between any of us and we'll tee it up tomorrow, the same deal as today ... I think it's great to be in this situation.
"The thought of playing the Masters just turns your stomach a little bit, you can't put too much pressure on yourself and I just have to go about my business tomorrow and the best man will win."
Davis had just one bogey all day, a six at the par-5 seventh, and his consistency was rewarded with three birdies on his backward nine.
"There's no point getting ahead of ourselves, there's still another day to go," Davis said of the final day scenario.
"You just treat it like any other golf tournament, but I guess after the tournament's finished one of us might be a little bit happier than the other - or someone else will have a great round tomorrow, so you just never know what's going to happen."
While Coletta's is having his first crack at the Asia-Pacific Amateur, Davis will be hoping to right the wrongs of 2015, when he was trailing eventual winner Jin Cheng by one shot heading into the final round which was eventually cancelled due to a nearby typhoon.
