That comes to -0.1 dbWAR — -0.8 runs with the bat, +0.0 on the bases, -0.1 for the position he plays, against replacement level. It includes no fielding: defensive runs are proprietary and are not estimated here, so the figure credits playing a demanding position but not playing it well.

Runners on includes runners in scoring position, which is the convention every reference uses. Rows under 25 plate appearances are marked thin — at that size a rate moves several dozen points on one hit. Counted from play-by-play, 2017.
Head to head
Put Alberto Rosario beside up to three others.
wOBA uses linear weights measured from this season's own play-by-play rather than published constants, and wRC+ is park-adjusted against that same league. dbWAR is our own open implementation — not fWAR or bWAR — and the full derivation, including its simplifications, is on the methodology page.
