no he really shouldn't. i don't think what he did was intentionally dirty, just clumsy and poorly executed. but you can't let a guy come in two feet wide of 2b, feet high, against the most promising young player on your team without doing something about it, so you hit him in the back or the butt once, and then let it go. repeatedly throwing at him would just be stupid and possibly start a beanball war where a cub player ends up getting seriously injured.
