I'm watching the Dbacks Nationals game. The batter ducks away from a close pitch and the umpire immediately calls Hit By Pitch. Oh wait, let's have a replay challenge! Now there is no camera angle on this play where you can CLEARLY tell he was or wasn't hit so you have to rely on the Umpire's call based on what he saw and heard, right? NOPE. Over-ruled by the man behind the curtain. I have no idea what Clear and Convincing evidence means so if anyone has a good explanation, please share it.
