The pose was awful. Plain and simple. Act like you've been there. Every pitcher at every level will jaw at you for that shit. He'll grow up, but he still looks like an ass there. He needs to get corrected, but I don't think the Nats have the stones to do it as they've catered to his every whim so far. It'll probably take a few in his ribs to teach him (or a hurt vet giving him the business).
Players policing themselves is why baseball is the best. No lame ass 15 yard penalties or techs for trash talking. You just take your life in to your own hands. Buncha non-basbeall fans running amuck in here. Can the NFL get back to doing whatever it is they do, so the mouth-breathers will go back to discussing that trash?
