The snow-hit WGC-Accenture Match Play Championship was set to restart at 1300 local time (2000GMT) after another delay on day two in Tucson.
Frost had been predicted and the resumption of play was pushed back from the scheduled start time of 0830 local time (1530GMT).
Ten of the 32 first-round matches had still to tee off, including those involving top seeds Rory McIlroy, Tiger Woods and Luke Donald.
At least no more snow was in the forecast and it was still hoped to make up some of the lost time before nightfall.
Less than four hours' play was possible on Wednesday and not a single game had been completed.
Ian Poulter, winner in 2010, stood three up on Scot Stephen Gallacher after 12 holes, while Thorbjorn Olesen led by the same margin against Wales’ Jamie Donaldson – the player who pushed him into second in Abu Dhabi last month.
Lee Westwood was two up on Spaniard Rafael Cabrera Bello after five and Justin Rose two up at the turn on South Korean K J Choi, although he had been four up after five.
England’s Chris Wood, who won his first European Tour title in Qatar last month, was level with Masters champion Bubba Watson after six.
Closest to winning was Sergio Garcia, whose first shot on his return will be a 12 foot putt to beat Thailand's Thongchai Jaidee on the 16th green.
