2018 ZiPS Projections – Arizona Diamondbacks
After having typically appeared in the hallowed pages of Baseball Think Factory, Dan Szymborski’s ZiPS projections have now been released at FanGraphs for half a decade. The exercise continues this offseason. Below are the projections for the Arizona Diamondbacks. Szymborski can be found at ESPN and on Twitter at @DSzymborski.

A perfectly average group of field players would produce something like 16 wins collectively in a season (that is, two wins times eight starters). The group of D-backs field players on the depth-chart image below is projected for roughly 15 wins collectively in 2018. By one definition, at least, this is basically an average offense.
By another, it’s not at all. Of the club’s eight likely starters, only one — Ketel Marte (599 PA, 1.7 zWAR) — receives a wins forecast that would round to 2.0. Paul Goldschmidt (638, 4.1), Jake Lamb (589, 2.5), and A.J. Pollock (510, 3.4) occupy one mode of this hypothetical distribution graph; the rest of the starting eight (minus Marte), the other.
The weakness for a club constructed thusly is its exposure to risk: an injury to one of the teams leaders can have catastrophic effects. This was the case for the 2016 edition of the D-backs, for example, when A.J. Pollock was unable to make his season debut until late August. The strength for such a club, meanwhile, is the ease of upgrading the roster. In the case of Arizona, finding an alternative to Yasmany Tomas (426, 0.4) in left field might represent the most expedient means to such an upgrade.
