I didn't even realize now much the defense had killed Giolito. I don't know what the leaders in spread between ERA and defensive adjusted ERA is, but 1.12 runs of difference, if it isn't the leader, has to be damned close. This year the MLB league average era is 3.97 current, so while we are talking about a drop off from last year of about 3/4 of a run, we are no longer talking about almost 2 runs worse, which is a huge difference.
All of the ridiculous hyperbole about non-tendering Lucas is misguided. Get the guy a real defense, and he should be back to normal.
