Unfortunately, a bunt has to be properly executed to be successful. You can't assume it's a 100% lock when you call for the play.
Ok, then pinch hit for him. Jordan Zimmermann could put down a bunt.
Yes, I know it wouldn't happen but my frustration level is rising very high with how he's playing. That 8th inning GIDP today was just the straw that broke the camel's back.
