— The boxing adage "you can't hit what you can't see" was applied to golf Saturday as the combination of pea soup fog and white balls forced a third-round postponement at the Farmers Insurance Open.
PGA officials spent most of the day impersonating lighthouse operators as they monitored the fog that blanketed the South Course at Torrey Pines.
"We basically lost the whole day," PGA rules official Mark Russell said.
Only two groups teed off Saturday and only one group completed its first hole before play was suspended.
Players will resume play at 7 a.m. on Sunday and, according to Russell, "play until dark."
Russell estimated the final nine to 12 holes will be have to be finished Monday morning.
Steady rain dampened, yet did not delay, the completion of Friday's second round in which 87 players made the cut and Tiger Woods held the 36-hole lead.
Fog, though, is a different story.
"You just can't see," Russell said.
There were times the skies appeared ready to clear as players scurried to the practice range.
Brandt Snedeker, the defending champion, arose at 5:30 a.m. in anticipation of his 7:40 tee time.
"I've warmed up three times already," he said at one point during the daylong delay. "I've putted for three hours, probably."
His putts were pointless.
Just as play appeared inevitable, however, the fog would roll back over the course.
Paying patrons waited patiently for the start of an anticipated weekend that had Woods positioned at 11 under par, with a two-shot advantage.
Monday finishes are nothing new for Woods at Torrey Pines.
At the 2008 U.S. Open, he needed a Monday playoff to hold off Rocco Mediate in a dramatic finish. Woods made a 12-foot putt at his final hole Sunday for force the playoff. He and Mediate were still tied after 18 playoff holes Monday before Woods prevailed in a sudden-death win on the seventh hole.
"I have been out here long enough to know that this is part of the game," Woods said of Saturday's weather postponement.
Woods, a six-time winner of this event, holds a two-shot lead over Billy Horschel at nine-under 135.
Six players are three shots back — Casey Wittenberg, Brad Fritsch, Erik Compton, Steve Marino, Jimmy Walker and Josh Teater.
