From what you described in your original post, I say: GOOD CALL! If coach has a problem, tell him the truth: runner never touched the plate, and when she went back to touch, the throw beat her. If the coach still has a problem, maybe time to give him the heave-ho. You should also have reported your partner for being an a** about it later. If my partner came up to me, I would have asked if he saw any of it CLEARLY.
