A final-round 75 proved enough for Chris Selfridge of Moyola Park to win the Irish Amateur Close Championship at Royal Portrush.
Twenty-year-old Selfridge won by two strokes from Mourne's Reeve Whitson and Gary Hurley of West Waterford.
Selfridge led by four at the start of play but had a double-bogey at seven and dropped another shot at the next.
"The longest I slept last night was an hour, said Selfridge. "I was nervous, but I got through it thankfully."
Experience was perhaps key for Selfridge who has never surrendered the lead in a tournament.
"I had a six shot lead at one stage and threw it away. I got through it in the end, just got over the line.
"No-one expected me to win today. I knew how good I was playing, I have never played this well.
"Ok, I shot 75 but the putts didn't drop and I got a couple of terrible breaks especially on seven where I made double from a perfect tee shot."
Whitson got within one shot of leader Selfridge at the 16th, but a bogey on 18 left the talented Mourne member two back, alongside Hurley who played his final round in two under par.
