Lahiri’s third round of one-over-71 took his total to six-under-204 for the tournament and placed him seven shots behind the leader, Rickie Fowler of the United States.
Anirban mixed an eagle and a birdie with four bogeys in the penultimate round.
The 2015 Asia No. 1 landed his approach within five feet for an eagle conversion on the par-5 third and sank a 33-feet birdie putt on the 12th.
Winless in more than a year, Rickie Fowler finished strong Saturday for a 5-under 65 and built a four-shot lead going into the final round of the Honda Classic.
Fowler made two birdies over the last three holes at relatively benign PGA National as everyone else around him was making mistakes.
Fowler holed a 10-foot birdie putt on the 16th, got a potential break with a ruling behind the 17th green that allowed him to use a putter instead of a wedge, and then closed with a drive so bold and big that he had only a 7-iron into the par-5 18th that set up a two-putt birdie.
That put him at 13-under 197.
Fowler was four shots ahead of Tyrrell Hatton of England, playing his first PGA TOUR event in Florida.
Protecting large leads is never easy, especially around a course like this. The forecast was for strong wind on Sunday, which could make it even tougher for everyone.
“I know I have the lead, and it’s nice to go out in front,” Fowler said. “But you still have to play, and especially around this place, it can jump up and bite you at any time.”
It never bit Fowler. He kept a clean card Saturday, and was never seriously in trouble. His longest par putt was from 5 feet, and he had only two others in the 4-foot range. His break came on the 17th hole when he went long into a clumpy lie in the collar of the rough.
Fowler immediately identified the area as newly sodded and felt his ball was in a seam of the new grass. He was able to get a free drop one club length away, and the ball hopped into the short grass, allowing for a simple two-putt for par. Fowler said the chip would have been relatively standard, and that he used putter only because of bare grass from where players had been walking.
But he was at his best on the par 5s.
Fowler, starting the third round one shot behind, hit a 6-iron on the green at the par-5 third hole for his first birdie. He finished with a 340-yard drive over the bunkers that allowed no more than a 7-iron into the green.
There also was small redemption from a year ago, when Fowler became the first player to go bogey-free over the opening 36 holes at PGA National. But on Saturday, he made no birdies, shot 74 and dropped out of the hunt.
“I did better than last year,” he said. “I’m definitely in a better position that last year.”
