How this is measured
Raw season stats from the MLB Stats API; ranks are among all 30 clubs, 1st = best in the stat's good direction. The better side of each row is in bold. Counting a team's “wins” across rows treats every stat as equal, which they are not — runs scored and allowed per game say more about a team than stolen bases do. Nothing is adjusted for park or schedule.
