SDS,
A runner needs to have intent to be called out for interfering with a thrown ball. A batter can, by 6.06c, be penalized for interfering with a ball thrown by the catcher. Yes, I know 6.06c says "throwing", and you can try to argue that means only the throwing motion, but MLBUM 6.8 says "the catcher's throw". J/R Ch. 13 makes clear that interference may be called if the actual throw hits the batter. Or you could look at the last paragraph of MLBUM 6.10, which also illustrates the point.

NFump's scenario above is batter's interference.
