Fritsch withdrew Saturday at CordeValle Golf Club because of a bulging disc in his back. He was at 5-under 137, six off the 36-hole lead. Fritsch was scheduled to go out with Vijay Singh and Jeff Overton at 11 a.m. PT.
Because of early-morning fog concerns, the Tour moved back tee times, and implemented threesomes and split tees. The final group is off at 11:50 a.m.
