Bautista should be given nothing if for any other reason to show that if you don't fight back you won't get suspended. A suspension for Bautista sends the message that throwing haymakers is your best option because you are going to get suspended no matter what.
I'm a little surprised at the 8 games for Odor because there were a lot of aggravating factors. He tried starting s*** two weeks ago, he's caused brawls in the minors, he threw low trying to hit Bautista, he pushed, punched, etc. at multiple players, and he made incendiary comments about the whole incident.
Bautista is the exact opposite. He was beaned, thrown at by Odor, pushed, punched and aggressively bear-hugged the entire time and he didn't do anything other than make a slide that only violated the new rule (but he didn't even make contact). Those are all mitigating factors that should make whatever suspension he gets a game or less.
