The 15-time major winner carded a 4-over-par 75, which included a double-bogey on the course’s shortest hole.
The first round, which was Woods’ first since missing the cut at the Open Championship last month, leaves the 43-year-old some 13 shots adrift of the leader, Troy Merritt.
More worryingly for him, Tiger could now miss the cut for the first time in the FedExCup Playoffs, which also would jeopardize a return to East Lake for the TOUR Championship.
“We all knew it was soft out here with the rain last night,” he told reporters after the first round.
“I knew I had to go get it, post a low one, and didn’t do it. It’s certainly out there. Greens are soft. Fairways are soft. You can play aggressively and not have any real ramifications for playing aggressive.”
Merritt had no such issues, tying the course record with a 9-under 62 to take a one-shot lead over Dustin Johnson, who won The Northern Trust Open in 2017.
Kevin Kisner and Jon Rahm follow at 7-under, one shot ahead of Tony Finau, Rory McIlroy, Justin Rose and Webb Simpson.
Meanwhile, world number one and pre-tournament favorite Brooks Koepka is tied for 65th after finishing 1-under par on Thursday.
Here’s all you need to know ahead of the second round.
