Tiger Woods sank to the bottom of the US Open leaderboard after an opening round 10-over 80 on Thursday, but vowed to fight on and return to the top.
Without a major title since his US Open victory seven years ago at Torrey Pines, Woods chances of ending the drought seems unlikely after he carded the fourth highest score in his professional career to leave him 15 shots behind co-leaders Dustin Johnson and Swede Henrik Stenson.
"Not very happy, that's for sure. It was a tough day," Woods said. "It's one of those things, just got to work through it.
"I'm trying as hard as I can to do it, and for some reason I just can't get the consistency that I'd like to have out there."
Even in a year that has produced only disappointment Woods' display on the links-style layout was shocking.
Dressed entirely in black, the outfit perfectly reflected Woods dark mood as he piled up bogey after bogey and was unable to tap into any of the form and belief that carried him to the top of the world rankings and 14 major titles.
The 39-year-old American made a dreadful bogey, bogey start and went steadily downhill from there until he made a triple-bogey at the 14th that dropped him to 10-over.
Only one player, Rich Berberian Jr., a club professional playing in his first US Open, was below him at the time.
A birdie at the 16th was the lone bright spot before he finished with a bogey to leave him in tie for 152, one shot clear of Rickie Fowler and three in front of Berberian.
"The bright side is at least I kicked Rickie's butt today," joked Woods, managing to find a bit of humour in his performance. "I fought hard and that was my number (80).
"I couldn't grind out any harder than that. So that's just the way I played and unfortunately it was a high number today."
"They're all not easy to do. I've gone through tough phases in each one of these things and I've come out okay on the other side," said Woods.
"I haven't played enough. I haven't had a rhythm to play.
"I didn't play much last year and I haven't played much this year.
"Knee surgeries are pretty easy compared to a back surgery, the recovery time and for some reason, it's just a lot harder dealing with a nerve than a joint.
"Keep grinding and keep working."
Johnson, Stenson share Open lead
Dustin Johnson and Henrik Stenson set the first-round pace at the US Open on Thursday on a day of remarkable highs and lows as Tiger Woods shot an 80, his fourth-worst score as a professional.
American Johnson and Swede Stenson fired matching five-under-par 65s on a firm and fast-running ChambersBay layout while Phil Mickelson made an encouraging start with a 69.
The long-hitting Johnson piled up six birdies and a lone bogey to finish level with Stenson, who birdied four of his last five holes at the British Open-style venue in the year's second major, being played for the first time in the Pacific Northwest.
They were one stroke ahead of American Patrick Reed, while Americans Matt Kuchar, Ben Martin and amateur Brian Campbell trailed by two.
