Denmark's Thomas Bjorn was gifted the Dubai Desert Classic when Tiger Woods shot a disastrous seven on the last-hole.
The world number one is still looking for his first win of the year after a nightmare finish which was as dramatic as it was unexpected.
Even when Bjorn holed a nine-foot putt to level on the 17th the much longer Woods remained favourite for the stg£166,660 title with the 547-yard 18th to come.
Instead, however, he carved his drive into the trees, then went across the fairway into rough the other side and from there hit a 150-yard nine-iron short off the green - in water.
The double bogey seven meant that Woods, rumoured to have been paid in excess of stg£1.5million to appear in the event and four clear after seven holes of the third round, did not even take second place on his own.
He had to share that with Dubliner Padraig Harrington, who had been joint leader himself entering the back nine, but made costly bogeys at the 12th and 15th.
Ian Woosnam, 43 last Friday, was only one behind with eight to play, but he bogeyed the 15th and 16th and in the end finished joint fourth with Swede Mathias Gronberg.
