Brendan Jones' US Masters dream went down the sink as his approach shot to the 18th ran off the green into the water on Sunday.
The Canberran could have settled for equal fourth and played safe, but instead he attacked the pin in search of a birdie and a tie for second at the Australian PGA Championship at Coolum.
It would have capped a big year for Jones, who finished third on the Japan Tour money list and played in the US and British opens. He also finished second at last week's Australian Open.
But his aggressive approach to the 18th green missed its mark by a couple of metres and he ended up with a triple bogey that put him one-over for the day and dropped him to equal 17th.
If he had hit his mark he would have been about $91,000 richer and a chance to play in the US Masters.
''I won't get too many world ranking points for this, [the US Masters is] off the radar for next year, but the way I've played the last couple of weeks I've proved to myself I can mix it on any tour pretty much,'' Jones said.
''Disappointing to finish with a triple bogey - par would've finished me fourth - but that's just the way it goes.
''It's been a good year, I'm going to sit back and be happy with the year I've had.''
Fellow Canberran Matt Millar also finished equal 17th after shooting one-under on Sunday.
Like Jones, he felt it was a missed opportunity.
He said while it was nice to finish in the top half of fields, he needed to start converting them into top-10 finishes.
Millar finished equal 10th at the Australian Masters at Kingston Heath, before placing 23rd at the Australian Open.
He said Daniel Popovic's stunning victory confirmed it was possible to win a big tournament.
''I would've liked another top-10 at least out of the last two weeks after getting one at the Masters,'' Millar said.
''[Popovic's win] shows you that it's possible, but I've known that for a while now. I've just got to get all my ducks in a row.''
After having a few weeks off, Millar will keep busy at tournaments such as the Victorian Open before returning to the OneAsia Tour in March.
