Tiger Woods crashed out of the British Open at the halfway stage after a second round 74 in Scotland on Friday.
An error-strewn display left the world number one on a two-round total of 145, five over par, one stroke above the cut mark and ten adrift of leaders Tom Watson and Steve Marino.
It was only the second time since he turned professional that Woods has missed the cut in a major tournament, the only precedent being the US Open in 2006 which he contested shortly after the death of his father, Earl.
There had been no hint of what was about to unfold as he followed six straight pars with a birdie at the long 7th hole to move to even par for the tournament -- a position from which he expected to mount a challenge to win.
But his round fell apart with a disastrous run of holes around the turn, with double bogeys on both the 10th and 13th ultimately proving fatal to his chances.
"There is no doubt I'm frustrated because I was playing well," Woods said afterwards. "After seven holes I was right there in the championship.
"I thought if could post level par for the round I would probably be in the top ten. But I didn't do that. I went the other way.
"I had a few really poor holes in a row. I hit a few bad shots. It just seemed to be problem after problem and I kept compounding it.
"It is very disappointing. I just did not play certain holes well enough."
Woods has won three tournaments since coming back from an eight-month lay-off for reconstructive surgery on his left knee.
But he has not been able to add to his haul of 14 majors after finishing tied for 6th in both The Masters and the US Open.
"I have just not played well enough in the majors this year," he said. "In all the majors I've won I've played cleanly in all four rounds and I just haven't done it this year.
"I was on the range yesterday and I felt good. I was hitting it well. But unfortunately it was not to be today."
After bogeys on both the 8th and 9th, Woods sent his drive at the 10th flying into the long grass. With the help of dozens of spectators two balls were found but neither was the one they were looking and he was forced to mark his card with a double bogey six.
The situation was not totally desperate at that stage with the American then only four over -- right on the projected cut mark.
But a bogey on the 12th, where his drive ended in a fairway bunker, was followed by a second double bogey on the 13th.
The best golfer on the planet watched in disbelief as his chip failed to make it up the slope on the back edge of the green and rolled all the way back down. Woods then hit a poor approach putt and was unable to hole out from 15 feet.
A good approach to the 16th set up a 25-foot birdie putt which Woods holed to give himself a fighting chance of survival.
At the 17th, he had a lucky break when his second shot took a kindly bounce over the huge bunker at the front left of the green, the ball coming to rest just off the back edge, from where he was able to get up and down to get back to five over.
That meant a birdie at the last would enable him to squeeze into the last two rounds but a slightly over-hit approach meant he had to play a good chip to salvage a par that was just not good enough.
