Jack McDonald battled scorching conditions and a tough field to clinch the final EuroPro Tour event of the season at Newmachar Golf Club.
McDonald posted rounds of 69, 65 and 66 to leapfrog Jonathan Caldwell who had led the opening two rounds of play. The Kilmarnock Barassie golfer carded a sensational bogey-free final round to claim his maiden professional victory.
"I played great right through today so I knew I just had to keep it going," said McDonald.
"I'm just delighted to get the win. It feels amazing. The professional game is definitely different from the amateur game and I am just delighted to get the win. I am just going to enjoy it."
McDonald finished 16th on the Order of Merit following the season-ending tour championship on the EuroPro Tour.
"One box was ticked when I made the cut. All I was thinking was that I had nothing to lose and I was just aggressive, so I am glad it paid off."
McDonald, who had only one top-10 finish to his name before that week, took home £10,000 for his victory – more three times his earnings for the entire season.
Caldwell didn't do much wrong on the last day and can count himself unfortunate to narrowly miss out. He had rounds of 64, 67 and 70, the latter proving not to be enough to steal a win.
Paul McKechnie finished third outright with a five-under-par final of 67 that included six birdies and only one bogey.
John Parry signed for rounds of 65, 68 and 70 to tie for fourth, with Will Enefer and Tim Rice, whose 63 was the best round of the week.
