The reality is that the level of defensive play will effect your pitcher. Lots of times a pitcher will pitch well enough to win and get beat. However your have to keep asking the pitcher to learn his craft and pitch the way he know he should with out regard sometimes to the outcome. As he progresses the level of his defense will as well and you'll see the improvement in the outcomes. Just becasue a kid and blow hitters away the first time around does not mean he should not establish his other pitches. If your catcher can't handle the BB in the dirt you should still throw it if that is what the situation demands. The catcher will learn how to handle it. If your outfielders don't go back well on balls don't play them out of position to cover up. Continue to work with them in practice and let them learn how to do it right in games. Being the father of a pitcher I know it is tough but you have to have him take responsibility for what he has control over, making his pitches and defending his position. He can't worry about the rest of it. Tell him when he executes his gameplan perfectly then he can worry that his defense does not do the same.
