Andrew Putnam celebrated his first PGA Tour title after sealing a four-point win at the Barracuda Championship with a round of four-under 68.
Shane Lowry finished tied 15th, 16 points off the winner, with Graeme McDowell on + 31 points, Seamus Power on +21, and Padraig Harrington on +20.
The Barracuda Championship - formerly known as the Reno-Tahoe Open - uses a Modified Stableford format, which allocates points based on the number of strokes taken at each hole.
Eight points are awarded for an albatross, five for an eagle, two for a birdie, zero for a par, minus one for a bogey and minus three for a double bogey or worse.
Already leading the field as the final day began at the Montreux Golf and Country Club, Putnam picked up three shots on the way out, only dropping one on the fifth.
The 29-year-old scored two more birdies after the turn to complete the round with nine points, bringing his total to 47.
Chad Campbell bagged 11 points with a five-under-par 67 to place the American in second, while countrymen John Oda and JJ Spaun tied third after each picking up eight points by going round in 69.
William McGirt of the US shot the round of the day, picking up 20 points with a nine-under 63 that saw him card eight birdies and an eagle to rocket 43 places into sixth.
Having climbed up the rankings on day three, Ireland's Shane Lowry suffered a disappointing final round, carding one over par to eke out a solitary point and fall from just outside the top three into 15th with 31 points overall.
It left him tied with Scotsman Martin Laird, who dropped eight places after his one-under round of 71 afforded him only five points.
