He finished strong with two more birdies in his final three holes to remain in contention as he carded a 4-under 66. Tied for the lead with five holes to go, Putnam made bogey from the bunker on No. 14 and Kuchar birdied the next two holes to seize control.
His only birdie of the day came on the ninth hole, where he landed his third shot to seven feet and holed it for a birdie.
"Boy, to win two out of three events - it's insane to comprehend", said Kuchar, who missed the Tour Championship last year for the first time in eight years but has now taken his tally of US PGA Tour titles to nine.
The 40-year-old is also trying to win for the second time this season after capturing the Mayakoba Golf Classic in November.
Kuchar matched the lowest 36-hole score of his PGA Tour career. "To shoot seven-under back-to-back is unexpected, but certainly awfully exciting", said Kuchar, who finished his front nine by making an eagle on the par-five hole.
US veteran Matt Kuchar shook off a slow start and pulled away for a four-shot victory over Andrew Putnam Sunday in the US PGA Tour Sony Open in Hawaii. Those were the only players within five shots of the lead, and all of them are chasing Kuchar.
Super-consistent Marc Leishman is on track for another big US PGA Tour payday but the Sony Open title appears nearly out of reach going into the final round. Kuchar came out weakly, but made the 10-foot birdie putt. "If I just keep plugging along I know good things are going to happen". He won the Match Play Championship and the Memorial in 2013. But he had a good session with his swing coach in Dallas, and it paid off two weeks later on the Gulf side of the Mexican coast.

Putnam, who won the Barracuda Championship last summer and was runner-up to Dustin Johnson at the FedEx St. Jude Classic, moves into the top 50 in the world for the first time in his career at No. 45.
"I'm feeling a little let down right now", Putnam said after closing with a 68. "I look forward to the rest of the year to try and continue to see how great this year can be". "I have to stay aggressive". "Still got a chance". Marc Leishman, Hudson Swafford, Chez Reavie and Corey Conners were T-3 at 17 under.
"For not playing well at all and being on the bad end of the draw, to miss the cut by one is reassuring", Spieth said.
Peter Jung, who qualified by winning an amateur tournament, played in his first PGA Tour event.
