Wagner finished at 13-under 267 and won by two strokes at Waialae Country Club. The victory was his third on the PGA Tour after titles at the 2008 Houston Open and last year's Mayakoba Golf Classic.
"I played great. I'm fired up," Wagner said in a televised interview.
Third-round co-leader Matt Every struggled a bit on Sunday and carded a two- over 72. He tied for sixth place with Michael Thompson (67), Brian Gay (67) and D.A. Points (69) at 10-under 270.
