You guys are probably right. Yanking him after that inning may be a tad extreme. Saying nothing to him and just believing he will be harsh enough on himself, or that he knows better and will punish himself would be the worst thing you could do. A "talk" would definately be the middle road here. If it were me, though, I'd make sure that "talk" was pretty one-sided and that he understood where I was coming from at the end of it.
