Position
Runs for how hard his positions are to play, by his outs at each.
Shown for: batter.
Formula
The total over positions of that position’s runs per 162 games × his outs there / (162 × 27).
Our own model
Not checked against Savant. A season is written only when every check on the aWAR page passes.
Notes
The values are FanGraphs’ constants, from +12.5 runs at catcher to −17.5 at DH; ours swung more than sampling explains. Outs at each position come from Savant’s fielding leaderboard, and a designated hitter’s from his plate appearances in games he didn’t field.
Era caveats
aWAR begins in 2016
Savant’s fielding leaderboard begins in 2016, so 2015 has no aWAR and no part of it.
