Tiger Woods won't contest the final round of the Farmers Insurance Open after crashing to a 79 on Saturday.
The world No 1's miserable seven-over par round on the South Course at Torrey Pines catapulted him down to tied 80th and meant he fell victim to the secondary cut which eliminates those outside the top 70 after round three.
Woods, who has won the California event seven times and also captured the 2008 US Open there, mixed three birdies and two bogeys in his first eight holes after teeing off at the 10th.
But a double bogey seven at the 18th sparked a horror run which saw the 14-time major winner drop nine shots in seven holes.
He finally broke the sequence with a birdie three at the seventh - giving the galleries an ironic bow as he walked off the green - before chipping in for par at the eighth.
Tiger still risked the ignominy of failing to break 80 after duffing his greenside chip at his closing hole, the ninth, but he managed to hole a nine footer for par to shoot a 79 and finish on six-over for the tournament. However, it was still the joint third highest score of his PGA Tour career and his joint worst on American soil.
Woods now switches to the European Tour to contest next week's Dubai Desert Classic.
Meanwhile, at the top of the leaderboard, Gary Woodland leads the way on eight-under - a shot clear of fellow American Jordan Spieth and Aussie Marc Leishman.
Woodland had cruised to 10-under after a flawless first 14 holes which brought birdies at 1, 8, 10 and 14. But a rollercoaster finish saw him bogey 15, birdie 16, double bogey 17 and three-putt 18 for a par and a round of two-under 70.
Overnight leader Spieth dropped four shots in his first five holes but steadied the ship to card a three-over 75. Leishman, meanwhile, had a steady 72 featuring just one birdie and one bogey.
Big-hitting Woodland said later: "The golf course is really tough. It's as tough as any (US) Open I've played.
"The rough is up, the greens are firm and fast, there's just no let-up, the golf course just keeps coming at you."
