The procedure used to determine if Rory's ball was embedded seemed suspect. Rory didn't touch the ball and called for an official (correctly done, unlike Reed); the official removed the ball from the lie (correct again); she then stuck her finger into the depression to feel for a hole. No visual inspection occurred, I don't think.
I've had many balls "embed” in heavy grass that made a round indentation in the grass but did not pierce the surface. It seems to me that only a visual inspection could definitively answer that question. John VDB, what say you?
