		| Originally posted by DG Granted, I would have to see the play, but if the runner coming from 3rd contacts the catcher up the line, while he is receiving the ball I could see an interference ruling even if contact was unintentional.  Interference is not measured by intent. If the runner has room to avoid, he should.

 Reference, please.
Fed 8-4-2g "INTENTIONALLY interferes with a throw or thrwon ball ..."
OBR 7.08(b) "He INTENTIONALLY interferes with a thrown ball"
If the runner moves into the fielder, you'd (probably) have intent.  Otherwise, it's just a train wreck.
