Furyk also par'd his 17th hole, a par 5, so it could have been lower yet!
As interesting though is this: Tiger was assessed a 2 stroke penalty for moving an impediment that caused his ball to move. Had he replaced the ball, it would have been a one stroke penalty. There is video.
I think I'm with Tiger on this one. The ball didn't move forward or backward. it may have settled down a bit, but that causes me to stop and think, how the hell does he replace that ball and only incur a 1 stroke penalty?
