Scotland's Marc Warren won the Johnnie Walker Championship title after beating Simon Wakefield in a play-off.
The 26-year-old, the rookie of the year in 2006, won his second European Tour title with a five-foot birdie putt on the second play-off hole.
Warren had forced the play-off with a birdie at the 18th while Wakefield, in the group behind, missed a 12-foot putt that would have given him victory.
England's Wakefield also missed from nine feet on the first play-off hole.
Warren's previous Tour win also came via a play-off win on the second extra hole at the Scandinavian Masters last August.
He went into the Gleneagles event with six missed cuts in his last eight tournaments and started the final day with three bogeys in the first four holes.
But he recovered with eight birdies in his closing 13 holes to end with a four-under 69.
If I'd putted well I would have won
"My coach Bob Torrance told me to stop being so hard on myself and it's an incredible feeling to win here in Scotland," he said.
"I feel sorry for Simon, he was looking for his first win. He had the lead for most of the day but I managed to pip him at the post."
Wakefield, still winless in 181 Tour events, was in a share of the lead with Fredrik Andersson Hed on nine under at the start of the day.
He saved par with a 14-foot putt on the fifth and claimed three birdies for a final-round 70.
"I am deflated," he said. "I held it together really well and what can I say? But at least I lost to a birdie and I didn't have a bogey all day."
Joint third, a stroke behind Warren and Wakefield, were Swede Martin Erlandsson and Dane Soren Hansen.
Lee Westwood was snapping at the heels of the leaders all day but had to settle for ninth after a closing bogey six.
He finished on eight under in a group including Colin Montgomerie.
"I didn't putt well at all," said Montgomerie. "It's getting better, but it's not good enough. If I'd putted well I would have won."
Defending champion Paul Casey, who was five shots off the lead going into the final day, had a dreadful fourth round.
The Englishman double-bogeyed three of the first five holes and finished with an 80 to end up on three over.
