Three Scots are in the field for the World Golf Championship knock-out event in Arizona, which begins on Wednesday.
Paul Lawrie, Stephen Gallacher and Richie Ramsay are in the 64-man field chasing prize money of more than 1.1 million euros.
Lawrie has been paired with American Scott Piercy and Gallacher faces the winner of the 2010 event, Englishman Ian Poulter.
Ramsay tees up against former Open champion Louis Oosthuizen.
Gallacher is first to tee off, at 14:45 GMT; Ramsay begins his tilt at 18:25 with Lawrie teeing off 30 minutes later.
