Scotland's Stephen Gallacher has lost to Ernie Els at the WGC World Match Play championship in Arizona.
Gallacher, the only Scot in the 64-strong field, lost the 16th and 17th to par and missed from five feet for a winning birdie on the 18th.
The Scot then bogeyed the first extra hole at Dove Mountain as the South African secured victory.
Former champions Ian Poulter and Luke Donald also bowed out.
Poulter lost 2&1 to Rickie Fowler, while former world number one Donald, now 21st, lost 5&4 to Matteo Manassero.
Gallacher, 39 has been in impressive form recently and defended his Dubai Desert Classic title.
The £250,000 first prize for Gallacher's third European Tour title lifted the Scot to seventh in the Race to Dubai and 14th in the European Ryder Cup points list.
