VANCOUVER, British Columbia (AP) - A case of vandalism on one of the greens didn't affect play Saturday at the RBC Canadian Open.

Grounds crews discovered bleach had been poured on the grass on the eighth green, a par-3 hole at the Shaughnessy Golf and Country.

"When they found it, they did all they could to wash it out," said Bill Paul, the tournament director. "We are investigating it right now with Vancouver police. That's all there really is."

The damage was discovered at around 6 a.m. when superintendent Rob Barr was inspecting the course. Some brown streaks could be seen on the green, but it didn't affect play in the $5.2 million tournament.
