You will not be surprised to hear that Coors Field is the National League park where the D-backs have had the highest ERA in their franchise history. At 5.69, it’s more than three-quarters of a run more than the next highest active venue, Busch Stadium’s 4.71. [Though a pair of defunct parks, old Yankee Stadium and Target Field in Minneapolis, both sit over 6.00, albeit only in a half-dozen games] It’s also close to a run and a half higher than the team’s overall ERA since 1998, giving you some idea of how tough it is to pitch in those conditions, even with a humidor.
