A stellar closing round score of 61 proved just enough to propel American William Mouw to a maiden PGA Tour title at the ISCO Championship in Louisville.
The 24-year-old entered the final round one-under-par and seven strokes back, but quickly set about climbing the ladder.
He opened with three straight birdies and picked up two more strokes headed to the turn to reach the halfway mark five-under-par for his round.
Mouw's momentum carried into the back nine as he birdied holes 10, 11, 13 and 17 without dropping a shot.
After a two-hour wait, Mouw’s victory was confirmed when third-round leader Paul Peterson missed a 55-foot birdie try on the par four 18th.
Conor Purcell closed with a 72 to to finish in a tie for 45th.
England’s David Skinns was fourth after an even par closing 70.
