The 20-year-old, who was controversially left out of next weekend’s Walker Cup team, produced a brilliant last-day performance to win the Aberdeen Asset Management-sponsored event at Meldrum House.
He stormed into the lead with a third-round 62 then closed with a 68 for an aggregate of 14-under-par to win by two strokes from Hayston pro Stephen Gray.
Fenwick closed with a pair of 68s to finish third on 270, one ahead of former Mortonhall man David Patrick.
“I’m taking a lot of positives from the way I’ve played this week,” said Fenwick, who is playing full-time this season after finishing his PGA training at Dunbar.
Wright, who shared the lead at the halfway stage, had to settle for fifth spot after closing rounds of 69 and 70.
But, coming on the back of a top-40 finish in the Johnnie Walker Championship at Gleneagles, the West Linton pro was also upbeat.
“I’ve hit the ball well again and it was only probably down to a bit of tiredness that I let some shots slip out there,” said Wright.
Along with both Fenwick and Patrick, he’s heading for West Lothian next week for the Scottish Young Professionals’ Championship.
