Alexander Levy made a birdie at the second play-off hole to overcome Ross Fisher and win his third European Tour title at the Porsche European Open.
With the tournament reduced to 54 holes due to fog delays over the first three days at Golf Resort Bad Griesbach, the Frenchman entered the third and final round with a four-shot lead at 17 under after 36 bogey-free holes.
He made three bogeys in his first five holes, though, and with playing partner Fisher closing the gap to one as the pair stood on the final tee, a tense finish was in store.
A closing bogey from Levy meant the pair had to go back up the last and after two pars at the first attempt, the 26 year old holed a quick 18-footer down the slope for a birdie and the victory.
The win makes Levy just the second European Tour player in history after Paul Lawrie to triumph over 72, 54 and 36 holes, following his victories in 2014 at the Volvo China Open and the weather-reduced Portugal Masters.
Levy missed his first three cuts of the season and then had two spells on the sidelines in the summer due to injury but has been in fine form since his return at the start of the month, finishing in a tie for seventh at last week's Italian Open.
"It's unbelievable," he said. "On the 18th putt I saw the line and I said to my caddy, 'I've got it'. I felt good, I felt the speed and I putted it very quickly.
"It's too good to have this feeling after two years of no wins, it's very nice.
"It's tough to say that it's the best one [win]. I have a very nice feeling and I worked a lot the last few weeks to have this one. I was close last week but didn't play good on Sunday and this week I managed my things to have this trophy in my hands.

"I didn't play really good on the front nine. I was thinking about the score and not on my own game. I stayed patient and I started to play really good on the back nine."
A 40-foot birdie putt on the second looked to have steadied his nerves after a bogey on the first and he took advantage of the par five third before recording back-to-back bogeys after loose tee-shots.
Another birdie on the par five eighth got Levy back to where he started the day but with Fisher making birdies on the first, third, eighth and ninth, the pressure was on.
Both men took advantage of the tenth but Levy then pulled away as he made it four out of four on the par fives on the 12th before putting his tee-shot on the 14th to 15 feet and getting to 20 under.
The leading duo birdied the 15th but a three-putt from Levy and a 20-foot birdie from Fisher on the next resulted in a two-shot swing and when Levy put his second shot into the spectator area on the last, extra holes were required.
"Hats off to Alex, it's always going to be tough against a great player like him who closed out in Portugal very well," said Fisher. "He got off to a little shaky start so myself and Michael [Jonzon] just needed to put some pressure on Alex from the start.
"I felt like I played pretty flawless on the front side, kept it going on the back. All you can do is hit good putts, I didn't leave one short today which is a positive sign."
Hats off to Alex, it's always going to be tough against a great player like him - Ross FisherSwedish duo Robert Karlsson and Michael Jonzon finished three shots out of the play-off at 16 under after rounds of 65 and 68 respectively.
Karlsson had eight birdies and a double-bogey while Jonzon - who was fourth reserve and only knew he was playing on Wednesday - endured a rollercoaster round, dropping three shots in a row on the front nine from the fifth before bouncing back with five birdies in six holes from the 11th.
Austrian Bernd Wiesberger was then at 15 under, a shot clear of local favourite Martin Kaymer and two ahead of another German in Florian Fritsch, English duo Richard Bland and Matthew Southgate, France's Grégory Havret, Spaniard Eduardo de la Riva and South Africa's Jean Hugo.
