Russell Knox rolled in two incredible, near-identical putts on both the 72nd and first play-off hole to claim the Dubai Duty Free Irish Open.
It was an epic end to a hugely successful event that attracted 94,239 fans over five days - 27,055 yesterday - making it bigger than the preceding Irish Opens at The K Club and Portstewart.
The Scotsman needed to hole his 40-foot birdie putt on Ballyliffin's 18th hole to get to 14 under and a chance of a playoff with New Zealand's Ryan Fox.
The New Zealander had that putt for the title but missed on the high side and the pair were left to go back up the last.
Knox grabbed a huge boost to his round when he landed his second shot at the uphill par-5 fourth hole to some six-feet right of the flag and found the bottom of the cup for an eagle 3.
"I would love to win the Scottish Open as well and for me to be playing in the Open at Carnoustie, one of the best courses in the world, I'm very happy".
On the winning putt in sudden death, he added: "I said to (caddie) James, "well, we've already made this putt". "It's so hard to win tournaments". I mean, that's a bit of a bonus.
"I hit the shots I wanted to down the stretch, felt comfortable out there and it was close".
While disappointed at not winning Fox still earns almost $1.5 million for finishing runner-up and will tee off in the third major of the year the Open at Carnoustie in two weeks time.
Knox has also leaped to 8th on the European Ryder Cup "World" points table after being snubbed two years ago for Hazeltine "wildcard" selection.
While missing out on the ultimate goal, Fox did get a handy consolation prize, with his second place finish booking him a spot in the Open Championship - his third appearance in the last four years.
After moving day, South African Erik Van Rooyen was in control with a four shot lead heading into the final round. He then birdied the sixth and then followed a birdie-bogey start to the back nine with a birdie at the 12th and another at the 15th, to join Fox and Spain's Jorge Campillo in a tie for the lead. I stood over the putt.
