to run and drawing a throw may be considered a form of interference.
This does not apply to the batter-runner running on the dropped third strike rule.
PENALTY: (Arts. 16, 17, 18) The ball is dead and the runner closest to home
plate at the time of the interference shall be declared out. Each other runner
must return to the last base touched at the time of the interference.

Did the retired BR do this?

Minus the contact with the ball by the retired BR, would F3 had been able to retrieve the dropped ball and been able to make a play on R1?

My real question is this: Is the act alone enough to call interference or do we also have to consider what would have probably happened minus the act?
