IRVINE, Calif. -- Forget "Fore!"

"Fire!" was the cry of the day for a golfer whose off-target swing sparked a 12-acre blaze in Southern California.

The golfer at the Shady Canyon Golf Course in Irvine landed a shot in the rough Saturday. On his next swing, his club snagged a rock, causing a spark that lit the rough ablaze and eventually attracted 150 firefighters to the scene.

Fire officials say the fire burned through the rough, into vegetation next to the course and over two dry, brushy hillsides.

No charges were filed against the golfer, whose name was withheld.
