Kooch, who opened with rounds of 63-63, stayed on track with three birdies on the front nine and carded a 54-hole score of 18-under 192.
Just like that, his lead was three shots, making for a pleasant walk up the par-5 18th. He joins Xander Schauffle in the two-win club for this season and now has almost eight months to notch the first three-win season of his long, consistent and successful career. If I keep plugging along, I knew good things would happen.
"Good, steady golf, " Kuchar said.
Kuchar ended a almost five-year drought when he won the Mayakoba Classic in November, his eighth PGA Tour win, and he said it was a good recent experience to have in the memory bank.
Kuchar ran off four birdies in five holes to start his second round on Friday, handled the par 5s at Waialae again and finished with another round 63.
Lahiri bogeyed the 460-yard par-4 sixth, getting on the green in 2 and three putting, moving him to one-over for the round.
Putnam made his only mistake with a 9-iron into a deep bunker left of the 14th green, leading to bogey.
The only other time Kuchar won twice in the same season was in 2013, when he won the Match Play Championship in Arizona in February and the Memorial in early June.

Overlooked for last year's U.S. Ryder Cup team after an inconsistent summer, he hit the ground running in the new season and a win at the Mayakoba Classic in November, the eighth of his career, ended a five-year victory drought.
He finished at 22-under 258, the third-lowest total in Waialae history behind the PGA Tour record of 253 by Justin Thomas in 2017 and Jimmy Walker's 72-hole score of 257 when he won in 2015. However, his bunker shot got the flawless bounce off the green and one more off the flagstick for an impressive ending.
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.

"I missed couple putts early but I was awfully steady, played bogey-free".
"I want to see how great this year can be", Kuchar said.
