NAPA, Calif. -- Johnson Wagner chipped in for birdie and took a 1-shot lead in the Safeway Open by keeping bogeys off his card in the rain Saturday at Silverado.
Wagner was at 15 under par through 15 holes when the third round was halted as rain caused puddles to form around the edges of the green. Scott Piercy was just short of the 16th green when he told tour officials he couldn't play his shot because of the water.
Piercy was in the last group with Wagner and at 14 under. Patton Kizzire was at 14 under through 16 holes.
Paul Casey was 2 shots behind and also in the final group. Casey hit a tee shot on the par-5 fifth hole that clipped a tree, ricocheted somewhere and was never found, costing him 2 shots.
Phil Mickelson hit a wild tee shot on the par-5 18th and made bogey for a 69, leaving him 6 strokes back.
They were still in the game, mainly because of the rain. Shots became longer. Putts became more difficult to hole. The players still on the course, who included Martin Laird at 12 under through 16 holes, were to return Sunday morning.
Starting times for the final round already have been pushed well forward because of more rain in the forecast.
No person was more responsible for the PGA Tour's season-opening event having a decent chance to finish than JT Poston. In his first PGA Tour event, he holed an 8-foot birdie putt on his final hole of the second round for a 69 that moved the cut line to 3-under 141.
That meant 70 players made the cut. His birdie knocked out 16 players.
Piercy still had the lead after finishing his second round in the rain-delayed event Saturday morning. He made only one birdie coming in for a 67, but that was enough to give him a 3-shot lead over Casey and Wagner going into the third round.
Casey had another lost ball late in the second round, but this turned out much better. He was about 30 seconds away from abandoning the search when a spectator held up a ball with the Nike swoosh and a blue pen dot and said, "Is this it?" The spectator had found it in the hazard, so while Casey still had a 1-shot penalty, he was able to drop away from the grandstands and save par for a 68.
Casey birdied the par-3 second hole in the third round from 6 feet, and he was on the verge of getting within a shot of Piercy with a 4-foot birdie putt on the next hole until he missed it. Two holes later, the lost ball led to double bogey.
Piercy dropped a shot on No. 6, though it was a good bogey. He was stymied by a tree from the fairway and right of the green, played back to the fairway and hit a 100-foot pitch-and-run to 2 feet. He also missed a pair of birdie putts inside 6 feet. One was at No. 8, downhill with a wicked break from right to left. The other was on the 10th hole.
Wagner, meanwhile, plodded along. He was short of the green on No. 8 when he chipped in for birdie, and his chip from short of the ninth green lipped out. He pulled within 1 shot of the lead with a short birdie on the 10th, and caught Piercy with a 30-foot birdie on the 12th.
Piercy fell out of the lead with a bogey from just off the 14th green.
Kizzire started the third round 6 shots behind and made up ground quickly with five birdies on the front nine, only one of them longer than 12 feet. He finally dropped back in the rain, three-putting the 14th when his birdie attempt rolled some 6 feet by.
Cody Gribble, the lefty from Texas, was having the best rookie debut and was 3 shots off the lead until a double bogey on the 17th. He was at 10 under and in the rough left of the 18th fairway when play was halted.
