Based on what she says in this video, because the umpire on the field didn’t indicate that he was safe because of being pushed off the base, the replay officials considered that they were to determine if the player was ever off the base and being tagged, because the push off rule is a judgement call and can’t be challenged.

If that’s the case, then the Guardians are penalized because the umpire on the field made that technical mistake, which is exactly the whole purpose of replay in the first place.

Hopefully umps can learn from this and be sure to indicate that the player is safe because of the push-off rule to avoid it being challenged and overturned, which will prevent the tackling/intentional push tactic from becoming normalized. But stuff like this is just so unfortunate for baseball.
