How bad has Zach Davies been this season? He has made eight starts for the D-backs and given us an ERA+ of 56. There has been only one pitcher with as many starts and a worse ERA+. You’ve got to go all the way back to Edgar Gonzalez, who started ten games in the dreadful 2004 season to find that: he had an ERA of 9.32, an ERA+ of 49. That was a historically bad - not just for the franchise, but in the entire National League - team, rather than one contending for the division. So far, Davies hasn’t hurt the team’s overall record too badly: they are 4-4 in his starts.
