American Scott Piercy remains the leader by two strokes at the Safeway Open following a rain-interrupted second round.
Rain forced players from Silverado Country Club for more than two-and-a-half hours early on Friday morning, altering tee times, and the field never recovered as Piercy was through 12 holes.
The second round will now be completed on Saturday, with play due to get underway 7:45 a.m. PT.
After matching a course record of 62 at the PGA Tour's season-opening tournament on Thursday, Piercy was flawless with six holes remaining.

Playing in favourable conditions following the morning downpour, Piercy carded two birdies and an eagle to be four under through his second round.
Piercy's nearest rival and fellow American Johnson Wagner is two shots adrift after completing 14 holes, while Paul Casey is a stroke further back through 12.
Bill Haas managed to complete his round as he climbed into a tie for fourth position at 8 under overall.
Haas posted a 2-under par 70 to be in the mix heading into the weekend, alongside Troy Merritt (through 10) and Noh Seung-Yul (through eight).
Rookie J.J. Spaun (67) - who improved 36 positions - Patton Kizzire (through nine) and Trey Mullinax (through eight) are 7 under.
There are nine players tied at 6 under, including Phil Mickelson, who recorded a second-round 69, despite a difficult moment after the rain delay. The driver slipped out of Mickelson's hands on his first shot at the par-4 13th hole and while the shot went out-of-bounds, the veteran recovered to salvage a bogey - one of three on Friday.
