In this two-part series, we’ll take a dive into the Houston Astros‘ 2022 bullpen including some lesser known numbers and potential roles for those returning and the new members.
These numbers can be found in the Bill James handbook, which I’ve been reading this offseason and highly recommend.
Check out the book for detailed definitions, but here are some terms used:
Early Entry: Sixth inning or earlier
Leverage Index: Swing in win probability (average is 1.0)
- Easy:1 inning or less, first batter not tying run
- Regular: Any save that is not easy or tough
- Tough: Tying run on base when enters.
Clean Outing: Not charged with a run (earned or unearned) and does not allow inherited runner to score.
