Was this an appeal play?

We both know that...hence why I put force in quotes. I said it merely to be expedient.

Moreover, it couldn't be a normal play on the BR, because he had already acquired the base by passing it. Had he touched the base on the way by, he would have been safe.

I agree but I am wondering if that is how the U1 ruled.

This looked like relaxed action to me: the runner was not attempting to return when the base was tagged.

I disagree, the BR seems to be coming back to the bag to me. Regardless, say that in your opinion the action were unrelaxed, would you still consider a tag of the base to be enough for the appeal?
