Batter Hit by Catcher's Throw

[mbyron]

Play 1: F2 fields pitch cleanly, beans B1 with the throw to 3B, B1 just standing in the box after taking the pitch. I've got nothing, live ball, play on. Batter need not disappear.

Play 2: F2 misplays pitch, fumbles for it, hits B1 with the throw to 3B, B1 has backed out of box to avoid the play. This MIGHT be interference: if B1 has done what he reasonably could do to get out of the way, then play on. If he is just standing in the way, out of the batter's box, then call interference: batter out, runner returns.
