Bullpen Index
All 30 bullpens ranked by FORM: every arm a club has used in relief over the last 30 days is scored 0–100 on his season ERA and WHIP, then averaged weighted by innings pitched — the arm carrying the workload counts more than a mop-up man. Tap a team for the full report, with the two numbers only a bullpen has: save conversion and inherited runners stranded.

Pitchers who started a game in the window belong to the Rotation Index, not here — the two boards never count the same arm twice. Season totals are a pitcher's full year, so a reliever traded in August carries the numbers he put up elsewhere.
