So if the pitcher threw to an unoccupied "base" (Per defnition- in this case home plate) for the purpose of making a play (per Rule 8:05 (d) and which according to the RIM interpretation is perfectly fine- why is this not a proper appeal?
A PITCH is a ball delivered to the batter by the pitcher.
How can you not call a pitcher who is properly engaged with the rubber and throwing to home not a pitch?
