Wouldn't be a bit surprised. Zac didn't play horrible, but he missed a lot of easy throws, and threw horribly down field.
Bad day at the office? Maybe. But if this is indicative of his performance against the majors, we lose 3 more minimum and no chance to play in the CCG.
If Cody Green brings you at least as much, then he should be your answer. I would doubt he delivers worse results at the position. So if you even remotely think he could be "the guy" this year, you give him the start against LL and see what happens. So what if he only knows 20 plays. That's all you are going to need anyway.
