Ian Poulter has been drawn to start the defence of his WGC-Accenture Match Play title next week against 2009 Open champion Stewart Cink - if all the world's top 64 show up in Tucson.
And Thomas Bjorn's "reward" for hauling himself into the field with his
TaylorMade R11 Driver a week ago could be a duel with Tiger Woods.
With Phil Mickelson now deciding to return to the event after missing it last year - as did Woods in the aftermath of his personal problems - the only current doubt is thought to be Francesco Molinari.
The Italian's wife Valentina gave birth to their first child last weekend and he is making a decision later this week on whether to make the long trip.
The only change in the game's top 64 in the final week of qualifying was Dane Anders Hansen replacing former winner Henrik Stenson thanks to his joint runners-up finish at the Dubai Desert Classic.
American Steve Marino would have made it too if he had
TaylorMade R11 Driver the last hole to take outright second place in the AT&T National Pro-am at Pebble Beach, but he ran up a triple bogey eight after dumping a shot in the Pacific Ocean.
World number one Lee Westwood is seeded to face Japan's Toru Taniguchi in the opening round, while the only all-European clash in the provisional draw is Scot Martin Laird against Molinari's brother Edoardo.
Stenson, now ranked 65th, becomes the first reserve for the event and if there are withdrawals before next weekend the draw willo be adjusted.
