Lahiri, who is coming of top-10 finishes in his previous two starts in Asia, had as many as six birdies but also dropped four bogeys to be placed tied-28th.
South Korea's Whee Kim opened with a bogey-free, six- under 65 to take the lead in the opening round.
Making his third-consecutive start in the Shriners Hospitals for Children Open, Whee Kim was one shot clear of four players -- Alex Cejka, JJ Spaun, Ryan Blaum and John Huh -- besides Jimmy Stanger, who was also five-under but has not completed his first round.
His career-best finish since joining the PGA TOUR in 2015 is a T2 at the 2017 FedEx St. Jude Classic.
