Lahiri, who had holed a whole lot of long and crucial putts on Saturday, bore the brunt of the firm Sunday greens at the Riviera, and it cost him dearly. Na was left to lament on his back-to-back bogeys on the 12th and 13th holes, while Finau would rue two three-putts on his opening nine holes.
Looking for a strong finish, Lahiri began well with birdies on first and third holes at which point a Top-10 finish looked realistic.
Half of Watson's career wins have come at Augusta National or Riviera, but his chances on Sunday looked tenuous after a mediocre front nine that included three bogeys. And he was 1 over on his round at the turn, sitting two shots back of Cantlay at the time.
Tied for 42nd in the Genesis Open overnight after a disappointing, two-over 73 on Saturday, the four-time major victor birdied his last two holes to close with a three-under 68 and a likely top 25 finish on three-under par.
Bubba Watson acknowledged he had thoughts of retirement a year ago after a form slump but they were put on hold after his two-stroke victory at the Genesis Open in Los Angeles on Sunday.

Watson, who finished at 12-under 272, moved from No. 117 to No. 41 in the world, making him eligible for the World Golf Championship in Mexico in two weeks.
On Sunday, at a venue where he won previously in 2014 and 2016, three birdies in his final eight holes helped seal a two stroke victory and that magic number 10. Ben Hogan and Lloyd Mangrum are the only other three-time winners at Riviera. Hogan's victories include a U.S. Open. The UCLA alum could do no better than pars the rest of the way for a 71 to tie for fourth with Scott Stallings (68). But he went after birdie and watched the ball roll 20 feet down the hill, leading to bogey.
SHORT SHOTS: Phil Mickelson fired a closing 3-under 68 to notch his third straight top-10 finish. Mickelson has finished in the top-10 on each of his last three starts.
"Nobody thought that Bubba Watson from Bagdad, Florida, would ever get to 10 wins". So many emotions going through my head right now.
"You never know if you're going to play good again, and you never know if you're going to lift the trophy". So you never know if that was going to be the last time.
Watson admitted that he was close to giving up on golf as he battled with health issues and a loss of form over the past two years, but he chose to continue on his quest to reach his goal of 10 PGA Tour titles.
