Matt Every shot a final-round 66 to win the Arnold Palmer Invitational for the second successive year.
The American won last year's tournament after clawing back a four-shot deficit and had to come from behind again this time around to claim victory over overnight leader Henrik Stenson.
Every bogeyed the first but then made seven birdies, including one on the 18th where he holed from 18 feet to claim victory.
Stenson led until he bogeyed the 15th and then missed the chance to force a playoff with a 20-foot birdie putt on the 18th.
The win moves Every up to 26th in this season's FedEx Cup rankings.
