Volquez is a ground ball guy and the Reds had a left side with Keppinger and EdE there. I'm sure there were more than a few baserunners allowed as a result. I'm also fairly certain those extra runners contributed to the fatigue factor that many are pointing to in the second half. No matter, if his ERA is in the 4 range instead of 3, that is still pretty much number 2 starter territory in a park like GABP. Pretty much what I expected him to become when he was acquired. What's the worry?
