That comes to -0.1 dbWAR — -1.4 runs with the bat, +0.0 on the bases, +0.0 for the position he plays, against replacement level.

Head to head
Put Wei-Yin Chen 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.
