Sweden's Jonas Blixt held firm to win his first PGA Tour title as Johnson Wagner fell apart on the back nine of his final round at the Greenbrier Classic.
On a rain-affected day when low scores were not easy to come by, Blixt carded a three-under par 67 to finish 13 under overall, two clear of a group of four on 11 under which included Wagner, sealing not only his first PGA crown but also an invitation to the Masters.
The American led by two at the start of the day's play but, after being kept in the clubhouse until late in the afternoon by a three-hour rain delay, he could not build on the good work he had put in this week.
His lead was cut to one as he carded one birdie and one bogey on the front nine, but it was all downhill from there as further dropped shots at the 11th, 13th and 15th saw him slip to three over for the day and allowed Blixt in.
Blixt was in a tie for the lead when he birdied the 12th. He dropped a shot at the next, but found himself two clear when he holed a six-foot birdie putt at the 16th as Wagner was bogeying one hole behind him.
In the clubhouse at 13 under Blixt had a nervous wait as Wagner and Jimmy Walker completed their rounds, but they both arrived at the 18th two behind and when neither holed their tee shot the Swede could celebrate.
A tearful Blixt said on Sky Sports 1: "This year has been a bad year for me but to pull it off, I can't believe it. I'm really happy because now I get to go home and see my family.
"To be able to play Augusta - it's so many dreams come true. It's one week and the whole year turns around."
Wagner and Walker both parred the last to finish 11 under alongside two Australians, Matt Jones and Steven Bowditch.
