SANTIAGO, Chile --
Kisner, one of three 54-hole co-leaders, played the final five holes at the Prince of Wales Country Club 1-over par, but his 21-under 267 was enough to edge
Guy Boros (65) and hometown favorite
Five others were at 17 under.
Kisner figured he might be in the mix despite playing poorly in Panama and Colombia.
"I don't know why I won because I played so bad the last two weeks and missed the cut," he said. "It wasn't terrible, but my game wasn't there and I wasn't confident.
"This course just fit my eye really well. I knew when I played my first nine holes in the practice round that I'd have a chance here."
