What are my weaknesses? (or to be more politically correct - "Opportunities for Improvement")

I can't tell if my pitching staff has been underperforming or if they just suck. Will be getting rid of Guardado, I just acquired him as a throw-in in a trade to acquire Beltran and he's stuck on my roster till the trade finalizes.
