Joe Ogilvie won the US Bank Championship on Sunday after shooting a three-under-par 67 in the final round to finish at 14-under 266.
It is the first PGA Tour victory for Ogilvie who was participating in his 230th event.
Ogilvie was tied for the lead at 11-under with Tim Clark through 15 holes in the final round.
But a long-distance eagle on the par-four 16th and a birdie on 18 allowed him to secure the win at the Brown Deer Park Golf Course.
Ogilvie finished with four birdies and overcame three bogeys.
Conversely, Clark bogeyed number 16 and finished tied for second at 10-under along with Tim Herron and Charlie Wi.
It was the second consecutive second-place finish for Clark, who was runner-up last week at the John Deere Classic.
Still in search of his first PGA Tour victory, Clark also finished second in the 2006 Masters.
A four-time PGA Tour winner, Herron had owned a one-stroke lead at 12-under entering Sunday, but his two birdies in the final round were not enough to make up for the four bogeys he carded.
Wi came out of nowhere as he birdied four of the final five holes, but the late surge was not enough to challenge for the lead.
Steve Flesch, Bob Heintz, Jeff Maggert and Kenny Perry finished tied for fifth at eight-under.
