I really would have to say that if I am a spectator at a golf tournement, I would have my eyes open and would like to think I would not be the one getting hit. Wouldn't you agree?
On the other hand to answer your question. I have seen Phil hit someone at the TPC of Boston. The ball actually broke his watch, not sure what type. After Phil walked up, he unclipped his own watch (this I KNOW was a ROLEX) and handed it to the gentleman.
I guess after witnessing that, I would have to say the watch on the players wrist or in his bag.
How about that for a response?
