Play at the plate

[Forest Ump]

FED:

F2 is on the plate about to receive the ball. Runner coming in from 3rd crashes into the F2. No slide and no attempt to avoid. The runner only uses his hands to protect his chest. No forearm up. Runner did touch the plate as the catcher is receiving the ball and due to the crash the catcher does not make the catch.

Fed rule say he must legally slide or legally avoid. 8-4-2-b & c

I would call the runner out for not trying to avoid. I don't think this is an ejection for malicious contact.

Sound right? If not, please explain.

Same situation but now F2 is three feet up the line.

I have the same call or would you consider this now obstruction?
