League
Runs that bring every hitter’s total above average to zero for the season, by plate appearances.
Shown for: batter.
Formula
His plate appearances × the amount per plate appearance that brings every hitter’s batting, park, double plays, baserunning, fielding and position to zero for the season.
Our own model
Not checked against Savant. A season is written only when every check on the aWAR page passes.
Notes
Position values and Savant’s leaderboards don’t net to zero on their own.
Era caveats
aWAR begins in 2016
Savant’s fielding leaderboard begins in 2016, so 2015 has no aWAR and no part of it.
