Ward is really the only pitcher that is not meeting or exceeding expectations for me and he is dealing with shoulder issues. He got off to a good start before having this 'tired shoulder.' Other than that, the young guys (Marzi, Dettman, Tabakman) have all pitched well. Fischer has pitched well. Butler had a 5+ ERA the previous 2 years so his mid 4 ERA to this point hasn't been too surprising.
Having said that, I believe losing Blood has hurt but isn't something that has affected the team this year. Unless he was also the fielding coach.
