Schauffele’s final round of 62 on the par-73 Plantation Course at Kapalua goes down in PGA Tour history as the equal-second best winning round in relation to par behind only David Duval’s 13 under par 59 to win in Palm Springs in 1999 and matches Stuart Appleby’s 11 under 59 to win the 2010 Greenbrier event.
A bogey on his very first hole on day four hardly gave notice of what was about to unfold for Schauffele but eight birdies and two eagles followed - including a wedge hole-out at the par-4 12th - to give the American the year's opening title.
The 25-year old came from 5 shots off the 54-lead held by Gary Woodland, playing the final seven holes in 6 under par to defeat Woodland by one shot, Woodland unable to convert his three-shot overnight lead and settling for a 10th PGA Tour runner-up finish.
Two years ago, Schauffele was 300th in the world and will move to 6th with his win in Maui which is his 4th career PGA Tour victory.
Woodland - who was also chasing a 4th PGA Tour title - did little wrong, but he was unable to hold off the challenge of Schauffele.
Justin Thomas’ last round of 65 moved him into outright 3rd place one shot ahead of Dustin Johnson who shared 4th with Mark Leishman and Rory McIlroy, neither of whom could mount a serious final round challenge.
Jason Day was the only other Australian in the field and finished tied for 13th after a fine last round of 66.
