Bayan brought up a hat-trick over hurdles in the feature race of the day at Listowel.
The Gordon Elliott-trained four-year-old has won twice at Perth this summer, with a second-placed finish on the Flat at Galway in between, and again showed plenty of spirit in the Listowel Races Supporters Club Lartigue Hurdle.
The 5-1 favourite was joined by One Fine Day two flights from home, but the latter rather made a meal of the last hurdle to give Bayan a definitive edge.
Call Me Bubbles stayed on for second under Ruby Walsh, but Elliott's inmate had enough in reserve to strike by a length and a half in the hands of Davy Condon.
Bayan is owned by the Core Syndicate, whose members include racing presenter Gary O'Brien.
O'Brien said: "We're thrilled with that. We were very worried about the ground beforehand, to be honest, but he's been a smashing little horse and I think that's the fourth race he's won since we got him.
"Gordon has done a great job. We had a chat earlier on about whether we'd run or not.
"I was a little bit worried about the ground - he was as well, to be fair.
"If it hadn't been such a big race we might have pulled him out because Gordon does think he's a better horse on better ground.
"I'm absolutely thrilled we took the chance, it worked out great.
"It's great to have a winner here in Listowel."
Stablemate Toner D'Oudairies (7-1) had earlier accounted for Ancient Days by a length and a half in the John F McGuire Novice Chase for jockey Davy Russell.
Elliott said: "He was very disappointing the last day - they went very quick early and he half-sulked.
"Davy rightly pulled him up then when the race was over.
"He's not a novice for much longer and it was a nice pot so we said we'd let him take his chance."
Trainer Paul Deegan has high hopes for Shining Emerald (6-4 joint-favourite) after he sauntered 16 lengths clear in the Jet O'Carroll Memorial EBF Maiden.
Deegan said: "He had good form in the book. He ran a blinder first-time out in the Curragh, but the ground was just too quick for him last time at Leopardstown.
"We probably got away with it the first day. He likes to get his toe in and is above average.
"We'll maybe look at something like the Killavullan Stakes (Leopardstown).
"He'll be a bigger, stronger horse with a winter under his belt and will be a nice horse for next year."
Lanyard (4-1) made a successful debut in the Irish Stallion Farms EBF Median Auction Fillies Maiden, in which she accelerated between horses before scoring eased down by five lengths from Princess Pearlita.
Captain May (8-1) made every post a winning one in the Brandon Hotel Handicap, while 12-1 shot Romantic Stroll was another to benefit from positive tactics, with Wayne Lordan kicking her into a clear advantage a couple of furlongs from home in the Irish Stallion Farms EBF Fillies Handicap and she kept going to hold Surreal three lengths at bay.
