Northern Ireland's Graeme McDowell beat India's Jeev Milkha Singh in a play-off to win the Ballantine's Championship.
Both men entered the final round on 18 under par, but Singh looked to be heading for victory after opening up a three-shot lead on the front nine.
McDowell hit back and, after missing a putt to win it on the last, triumphed at the third extra hole in South Korea.
"This feels special and it's pretty sweet to get something this early in 2008," said a delighted McDowell.
"The ultimate goal this year is to make Nick Faldo's [Ryder Cup] team in September. I've given myself an opportunity to do that now. I've just got to keep working as hard as I have done.
"At the K Club I realised I should have been on the team. I was good enough to be on the team and I promised myself I was going to do everything to be on Faldo's team."
Ireland's Paul McGinley shot a 69 to finish third on 17 under, seven shots off the pace.
The day had started brightly for Singh.
He rattled in five birdies in the opening nine holes as the expected gusty conditions on the exposed Jeju Island course failed to materialise.
McDowell's charge gained momentum on the 10th with a 25-foot eagle putt.
A birdie on 12 drew him level in the inaugural European Tour event to be played in South Korea, but Singh edged ahead again with another birdie at the 13th - his fourth of the tournament at that hole.
I made a bad start today, I was three back after four holes and really had a game on my hands
McDowell, 28, hit back on 15 after hitting his ball to six feet before another Singh birdie at 16 was eradicated by a bogey on 17.
The Indian then had to sink a five-foot putt on the last to force a play-off.
Both parred the 18th twice before Singh pushed his birdie putt beyond the right edge and McDowell sank his to win his third European Tour title and his first since winning the 2004 Italia Open, also in a play-off.
McDowell added: "I made a bad start today, I was three back after four holes and really had a game on my hands, but I played the last 13 holes in six under par.
"It's a major relief to get it over with - he (Singh) just kept coming and I'm just glad I was able to hit one close to the flag at the last there."
