Interference then Collision-Did they get it right

[DG]

First I have Obstruction by pitcher. From there I can't say for sure since post not clear enough on what "collides with catcher" means. Was it malicious or not? If malicious, then MC supersedes obstruction and no score and runner ejected.

Ruling sounds wrong. Umpires must have judged malicious to eject. And it is not interference, but obstruction under consideration, and you don't score and eject, unless score happened first. Malicious contact supersedes obstruction.

Not avoiding contact is not a measure of malicious contact. I have never ejected a player for malicious contact after a conference. It happens instantaneously, I know it when I see it.
