Scott Piercy birdied one of his six holes left in the second round Saturday morning to complete a 5-under 67 and build a three-shot lead in the rain-delayed Safeway Open.

More rain was forecast as the first PGA Tour event of the new season tried to get on schedule.

Piercy set a target of making three birdies because of a pair of par 5s toward the end at Silverado. He made par on both those holes, though he had few complaints. He was at 15-under 129, three ahead of Paul Casey (68) and Johnson Wagner (67).

Casey saved a shot on the par-5 18th when he hit his second into a hazard, eventually took a drop and got up-and-down from 45 yards for par.
