Woods stood last at 13-over 155 for the tournament, his first tour event since last August after recovering from a back injury, and said he was healthy but simply needs more tournament work to try and recover his top form.
"I've still got a lot of work to do," Woods said. "I've got to continue with the process. I've got to keep things in perspective. Sometimes it's difficult. No doubt about it."
He will have missed the cut at least once in each year since 2008, when he won his most recent major title at the US Open at Torrey Pines.
Woods is set to play a tour event next week at Torrey Pines, where he has won eight times but last year struggled and missed a secondary 54-hole cut.
