Run Diff is runs scored minus runs allowed. RS/G and RA/G are per-game scoring and prevention. Pythag% is the Pythagorean expected win rate from runs scored and allowed (exponent 1.83) — a run-differential estimate of team strength. Luck is actual win% minus Pythag% (positive means a team has outperformed its run differential). Click any column to sort. Descriptive stats only · 21+.
