All in all, our pitching has been good, statistically speaking. As of 4:41PM 4/17/14:
#2 in the Major Leagues in strikeouts.
#7 in the Major Leagues in batting average against.
#6 in the Major Leagues in HR/FB (which indicates we've been unlucky in that regard)
We know we have a powerhouse offense (at least when 2/3 of our outfield isn't injured) so I think these pitching stats bode well for our future. Coming into this season, pitching was our #1 concern and it seems like Dipoto addressed that pretty well. His HR's notwithstanding, Trumbo is around the Mendoza Line and that trade is holding up pretty well as time passes.
