Please. He's unbelievably restrained as far as I'm concerned. I see nothing wrong with anything he's done. I would be hypocritical to say otherwise.
It's okay to realize that in your youth, you could have been better. My father, I just recently found out, threw a lot of tantrums when he was growing up. With his parents, his teachers, his friends ... he made it a point with me at a very young age that tantrums would not be tolerated.
My point is that being young is not an acceptable reason or excuse for bad behavior. It needs to be corrected. Bryce can not keep getting away with these outbursts. He knows he shouldn't do it. Its time to punish that behavior. Guys like Werth can mentor him, but ultimately the manager and general manager need for it to stop. It's starting to appear on the field now.
