Padraig Harrington went for broke in a suicidal bid to win the Zurich Classic of New Orleans and ended up tied fourth
After a back nine charge, the Dubliner needed an eagle at the 589-yard, par-five 18th to tie with clubhouse leader and eventually winner Andres Romero on 13-under par.
Going for the green in two from a fairway bunker, the Dubliner's five-wood splashed down in the lake protecting the right had side of the hole.
After missing the green with his fourth, he had to hole a 30 footer for a brave bogey six.
He said: "I had to make eagle and I was pushing it a little bit. I just got a bit distracted during my routine and I should have stood off it.
"But I had to take it on. There is a world of difference between first and second."
Harrington completed a third round 68 to move up to tied eighth and after a bogey at the fourth, he caught fire on the way home with five birdies in eight holes .
He birdied the par three ninth, par-five 11th and the 13th before holing twice from off the green at the short 14th and again at the 16th to get to within two shots of Romero on 11-under.
His final round 69 left him tied for fourth with Woody Austin, who finished with a double bogey seven, and Nicholas Thompson on 10-under par.
The event was marred by weather delays.
More than half of the field were unable to finish their rounds at TPC Louisiana on Saturday after heavy rain and lightning caused third round play to be suspended at 2:48pm.
Officials tried to bring the golfers back out later in the day and had vans loaded, but the storm intensified and the players had to return to the clubhouse.
Argentine Romero came out on Sunday, completed the rain-delayed third round in 65 and then fired a four-under par 68 to set the target of 13 under with the leaders still on the front nine.
After Harrington, Austin and Thompson failed to catch him, Romero watched in the clubhouse as Australia's Peter Lonard caught him on 13 under with at birdie at the 16th.
But the Australian bogeyed the short 17th, bunkered his tee shot at the last and failed to hole a 40 footer that would have forced extra holes.
