I hate seeing umpires trying to make the call on a play at the plate after a passed ball from the 1st base side of the plate. Far too often, they are blocked by all relevant action by the pitcher's back. MOST of the time, you can get a good angle if you start where Mike said - the back of the RHB batter's box, and adjust to the play based on where the throw is coming from and where the fielder making the play is coming from.
After reading Noobie's post I was wondering why F3 was covering home.
