Stewart Cink shot a steady 70, ending a dominant, record-setting week that culminated Sunday in his third RBC Heritage title.
Cink obliterated the lowest 36-hole score at Harbour Town of 13-under 129 shared by both Jack Nicklaus and Phil Mickelson.
Cink also broke the 54-hole mark of 16-under 197 set by Justin Leonard when he won in 2002.
Cink managed only two birdies and two eagles during his first three rounds.
Cink took a five shot lead into the final round and dared himself to put everyone in the hunt for the play by playing Justin Leonard.
Cink is the fourth player to win twice in the same PGA Tour season after turning 47. Sam Snead, Julius Boros, and Kenny Perry are the others.
After closing his final round with a par, Cink joined his family in a joyous celebration just off the green at 18.
