Performance in non-save situations

By Tangotiger, 09:13 AM

Geoff gives us the lowdown on one of our generations best relievers. I responded at ballhype:

B-r.com now has splits by save and non-save situations:

Three things jumped out:
1. lots of IBB in non-save situations
2. much higher BABIP in non-save situations
3. alot more multi-inning games in non-save situations

• Sabermetrics • Leverage_Index

Eric gives us his take:
http://mvn.com/mlb-stats/2008/08/07/closers-and-non-save-situations/

Notably:

* IP/G (SS): 1.21
* IP/G (NS): 1.24

* ERA (SS): 2.91
* ERA (NS): 3.15

* OPS (SS): .629
* OPS (NS): .652

* BB/9 (SS): 3.08
* BB/9 (NS): 3.39

* K/9 (SS): 8.12
* K/9 (NS): 7.79

SS=save situation, NS=non-save situation

No word on whether the three things I noted at top will be addressed.

I would ONLY look at save and non-save situations in which the pitcher entered in the 9th inning, and only look at 9th inning performance. This controls for the expectation that the pitcher will only pitch for one inning.

Definitely take out the IBB.
