Miguel Angel Jimenez claimed the Turespana Majorca Classic after an amazing late collapse by Jose Maria Olazabal.
Olazabal led by two shots with two holes to play but double-bogeyed the 17th and then bogeyed the last to hand his fellow Spaniard the title.
Jimenez had set the clubhouse target at six under after a superb closing 65 but was so confident Olazabal was going to win he had changed clothes ready for the prize-giving ceremony.
News then filtered through of Olazabal's troubles and Jimenez changed back into his golfing gear to watch the tense finale from the driving range.
Olazabal found the green on the 203-yard par three 18th but on the bottom tier and chose to chip rather than putt, but played a poor shot 10ft past the hole and missed the par putt which would have forced a play-off.
The double US Masters champion then did well to hole from five feet just to cling on to second on five under par, with England's Jamie Spence and Gary Emerson sharing third.
Ireland's Damien McGrane, who had led after the first round, slumped into a tie for 15th after a final round 74 left the Wexford professional on one under.
The tournament was reduced to three rounds because of lightning and heavy rain.
