Kurt Kitayama shot a six-under 65 and held on to win the 3M Open by one stroke for his second PGA Tour victory, as Seamus Power's challenge faded.
The Waterford native had a mixed round with five birdies and four bogeys to shoot 70, his highest round of the week. It left him on 13 under par, 10 off Kitayama.
One off the top after shooting 60 on Saturday, Kitayama managed 65, with eight birdies and just two bogeys, moving to 23 under.
That was one clear of fellow American Sam Stevens, who shot a second consecutive 66 to finish in outright second place.
