A year after winning by six shots, Ogilvy rallied from a two-shot deficit with 10 holes to play for a 6-under 67 and a one-shot victory over Rory Sabbatini on Sunday.
Ogilvy posted his eighth consecutive round in the 60s on the Plantation Course. He joined fellow Australian Stuart Appleby as the only repeat winners since this tournament moved to Kapalua in 1999, and he became the seventh player in the 58 years of this winners-only tournament to win in consecutive years.
"We knew what we had to do," Ogilvy said. "I'd never been in that situation. I'm happy and excited to get it done. I needed to make birdies, and I did."
Even though he trailed in the middle of his round, Ogilvy still had plenty of holes in front of him.
He played short of the par-4 14th, a 272-yard hole where most players were hitting driver, and pitched to 4 feet for birdie. And he took the outright lead with a 5-wood into 25 feet for a two-putt birdie on the 15th.
Sabbatini, who started the final round six shots behind, ran off five straight birdies on the back nine to seize the lead and closed with a 63.
Ogilvy finished at 22-under 270 for his seventh career PGA Tour victory.
U.S. Open champion Lucas Glover, bidding to become the second straight wire-to-wire winner at Kapalua, closed with a 76 and was 14th in the 28-man field.
