Louisville, Kentucky: Joe LaCava walked nearly every blade of grass on the 18th green at Valhalla Golf Club, jotting notes in his yardage book after stepping off the distances from every edge of the green to every possible pin position. It was just like any other Monday at a major.
The caddie just didn't know whether any of this information would be useful in the PGA Championship. LaCava was awaiting word on whether his boss - Tiger Woods - would be healthy enough to play the final major of the year.
"I'm optimistic," LaCava said after he finished charting the entire golf course. "I'm hoping he plays. So I'm just doing whatever work I would normally do."
