The 720 runs scored by Arizona, 17 behind Colorado, and about in line with their offense in general - the D-backs were third in batting average and second in OBP and SLG, with a triple-slash line of .264/.324/.414. They had the youngest offense in the league too, at 26.6 years old, and the majority of the players from 2015 will be back this year - and still on the right side of the aging curve, so there remains room for improvement through age. The main changes are in the middle-infield, where Jean Segura was swapped for Aaron Hill, and in right field, where Ender Inciarte was part of the package sent to Atlanta to bolster the rotation with Shelby Miller.
