Woods was on course for a first bogey-free round in any US Open since his closing 67 sealed a record 15-shot win at Pebble Beach in 2000 when he carded one birdie and 15 pars in his first 16 holes on Friday.
However, the 43-year-old then dropped shots on the eighth and ninth to card a highly disappointing 72 and leave himself with an uphill task over the weekend to claim a 16th major title.
Asked afterwards if he was "steaming", Woods told reporters: "Yeah, I am. Not a very good finish. Yeah, I'm a little hot right now. I just signed my card about a minute ago. So need a little time to cool down a little bit.
"I had a couple of opportunities there but overall I kept leaving myself above the hole. And unlike yesterday, when I missed it I missed in the correct spots below the hole, today I never had that many looks from below the hole. And the one I did have I made at 11."
Despite the poor finish Woods has not given up hope of adding a fourth US Open victory to the Masters title he won at Augusta National in April.
"Right now I'm still in the ball game," he added. "There's so many guys with a chance to win. We've got a long way to go, and, you know, we'll see how it shapes up for tomorrow.
"The golf course can be a little bit faster, a little bit more springy than it was today, and scores will continue to back up a little bit.
"They've got it (the course) right where they want it. It's just a matter of how much will it dry out from morning to afternoon. The fairways were a bit slow and soft. I don't think they put mowers on them this morning.
"And the short areas, the run-ups, man, they're firm. So if they get the greens anywhere like that, it will be a hell of a test."
