Leverage
Runs added for relieving in high leverage, at half credit.
Shown for: pitcher.
Formula
His runs above average × his relief share × ((1 + his pLI) / 2 − 1).
Our own model
Not checked against Savant. A season is written only when every check on the aWAR page passes.
Notes
Half credit, as at FanGraphs and Baseball-Reference. His runs above average are ifFIP runs + park − framing returned; replacement runs are not leveraged.
Era caveats
aWAR begins in 2016
Savant’s fielding leaderboard begins in 2016, so 2015 has no aWAR and no part of it.
