Deyen Lawson has scored an emphatic win at the $50,000 Queanbeyan Open, running away with the title by four shots.

The Gold Coast-based VIctorian added a seven-under 64 to his opening course-record 61 for a two-round 15-under-par total.

In second place was the fast-finishing Daniel Gale, at 11 under, while recently crowned women's Australian Amateur champ Grace Kim, playing a modified course, finished third at 10 under.

Lawson, who did his PGA traineeship at Curlewis, was thrilled with his winning performance, which came at the end of a long day with a two-hour weather delay stopping the leading group from hitting the course until just after 3 pm.

"I'm very, very happy," Lawson said post-round. " I played really good yesterday and hit it pretty solid today."

Lawson, who began the day with a two-shot lead, made a slow start, but as he neared the turn for home, his game picked up a gear.

"I didn't get want I wanted out of the round early, but on the 8th, I made a good birdie. I hit it to about 10 ft and rolled it in (and) got some momentum."

More birdies followed for Lawson as he rolled through the back nine, and by the 16th, he was three in front.

"I saw the leaderboard on the 10th and Jordan Mullaney had got to 10 or 11 under.

"I hit a good wedge to a foot on 11. I looked again after the 14th, and Daniel Gale had finished well, and 11 under was the total.

"On 16 I wanted to keep pushing, because the scores the guys have been shooting in the last month or so, well, you know anyone can come out and have a low one."

And push Lawson did.

A solid three-metal set up eagle on 16 and from there, with a big lead, the title was all but his.

"I was happy in the end to play solid coming home. It is a comfortable feeling walking up the last with that lead. It doesn't happen very often, but when you do, it's easy."

With Lawson already exempt for next month's NSW Open, the three qualifying positions went to South Australian Adam Bland, 2006 NSW Open champion Rick Kulacz and Murwillumbah amateur Lucas Higgins.
