Of course Gibby deserves blame, as do Cecil and Floyd, but Stroman's pitching to contact crap allowed Gibby to think about that decision in the 1st place. If Stroman is the strikeout guy he was in the MiLB and 2014, maybe he doesn't get BABIP'd and Gibby considers that Stroman might get a strikeout to get out of it.
It's all hypothetical but Stroman's pitch to contact crap failed him once again.
