Bullpen
Save conversion, holds and staff rate stats by club, sorted by conversion rate.
What this is and is not
The MLB Stats API publishes these at team level. Saves, blown saves and holds are relief outcomes; ERA and WHIP here are whole-staff figures including starters, and are labelled as such rather than presented as a bullpen-only number we cannot source.
