Catcher's Interference
 

Do you typically see the bat hit the catcher's glove, hear the bat hit the catcher's glove or watch the catcher's reaction when he's hit. I'm usually watching his reaction. I'm trying to get improve all my weaknesses, any advice?

I usually see it and hear it.

I usually see it and hear it, and then I call cather's obstruction.

That's how I handle it in FED. In OBR games, I see it and hear it and then I call interference.

I believe the call is 98% hearing it, and if there's doubt you watch for the catcher's reaction, which is almost always to give it away with a little shake of the mitt (he's checking to see if his fingers still work after getting smacked).
