Austria's Bernd Wiesberger saw a ninth European Tour title and potentially a Ryder Cup debut slip through his fingers after a dramatic finish to the Omega European Masters, where Denmark's Rasmus Hojgaard took victory.
Wiesberger held a one-shot lead with one hole to play at Crans-sur-Sierre, only to run up a double-bogey six and finish a shot behind Hojgaard on 13 under, who had set the clubhouse target after a flawless 63.
A second victory of the season would have taken Wiesberger into the automatic qualifying places for Europe's Ryder Cup team, with just two events remaining before Padraig Harrington's team is finalised.
Jonathan Caldwell finished with a 68 to end up on level par.
The 35-year-old began the day three shots off the lead and was still two behind Ross McGowan with seven holes to play, but birdied the 12th and eagled the 14th to open up a two-shot lead.
A bogey on the 15th was swiftly followed by a birdie on the next to restore Wiesberger's two-shot lead, before Hojgaard birdied the 18th to complete his last six holes in five under and pile on the pressure.
The pressure proved too much for Wiesberger to handle, a pushed tee shot into a fairway bunker on the last followed by a mishit approach into the pond surrounding the green.
Following a penalty drop Wiesberger hit a poor pitch on to the green and was unable to hole from 35 feet for a bogey to force a play-off.
Former Open champion Henrik Stenson boosted his case for a Ryder Cup wild card by following up his share of fourth place in last week's Czech Masters with third place in Switzerland following a closing 63.
