The Diamondbacks come into this home-stand with the fourth-best road record in the National League, but the fourth-worst record in their own park. This is almost entirely a result of the offense struggling there. Across the National League, the average home ERA is 0.30 runs better than on the road, and the D-backs are pretty close to that. Actually, they’re a bit better, with a home ERA that’s 0.40 lower (3.97 vs. 4.37). At the plate, though... The average NL team hits 28 points better at home; the D-backs, however, hit a remarkable 89 points worse on their own (artificial) turf.
