At the 477-yard par-4 13th, Lahiri's tee shot went 269 yards to the right rough, his second shot went 180 yards to the right front greenside bunker, and his sand shot went 29 yards to the green where he had a two-putt for a bogey.
Matt Kuchar overcame three early bogeys that cost him the lead with flawless golf and two key birdies on the back nine to close with a 4-under 66 and win the Sony Open for his second PGA Tour title this season. After breaking a four-year winless streak at the Mayakoba Golf Classic in November, Kuchar now has the second multi-win season of his career.
Kuchar matched the lowest 36-hole score of his PGA Tour career.
Putnam, who played college golf at Pepperdine and claimed his first PGA Tour victory a year ago in the Barracuda Championship, capped his 67 with an eight-foot birdie putt on the last hole. Those were the only players within five shots of the lead, and all of them are chasing Kuchar.
Kuchar's final-round 66 put him at 22-under 258 for the tournament, with Putnam finishing at 18 under with a 2-under 68 on Sunday. Kuchar came out weakly, but made the 10-foot birdie putt.
"Kuch is playing well, so I feel like I've got to get out there and make some birdies if it's not too windy", Putnam said.
"I found some good stuff between seasons ... and then things really heated up in Mexico", he said. Just needed to make some better swings. His best season to date probably came in 2013 when he won the Memorial and the WGC-Match Play Championship en route to $5.6 million in earnings.
Putnam, who won for the first time past year in the Barracuda Championship held opposite a World Golf Championship, did his best to stay in reach.
"I didn't hit the ball as well as first two days, so glad the putter was still warm", he said.
"Apparently, I need to go buy a lottery ticket today", Reavie said.
He tied third with Americans Hudson Swafford (64) and Chez Reavie (67) and Canadian Corey Conners (64). He carded one under overall after rounds of 73 and a much-improved 66 in his first event of 2019.
Love, who first played the Sony Open in 1986, missed by one shot matching the lowest 72-hole score of his career. Along with his runner-up finish in the Sanderson Farms Championship last fall, he has almost as many FedEx Cup points as previous year when he finished at No. 130.
Putnam's birdie at the third and a series of solid pars proved enough to take him into the lead, which he maintained at the turn when he matched Kuchar's birdie at the long ninth.
