Closer Identifier Algorithm Results for July 23

Joel Hanrahan, PIT

Changes for this week: Surprisingly, Alfredo Aceves has regressed into “lose” status. His k/BB slipped to 2.4 this week, which also weakened his BPV below the CIA minimum of 80.

Brett Myers’ trade to the White Sox results in a job loss, and another “hit” for CIA. I have lowered CIA’s success rate to 15-3, since certain players that counted as “hits” never really had a share of the job–Mark Melancon, Shawn Camp and James Russell for example. The current record is being as fair as possible, but if you think I missed someone let me know.

Jared Burton, Francisco Cordero, K-Rod and Sergio Romo were added to the spreadsheet this week. Their roles are not yet fully defined enough to merit a determination of what share of the job they have, but we include them anyway as newsworthy.

The current version of CIA:

1. Does the pitcher have a share of the closer’s job? In the cases we are writing about this will usually be yes, but it should apply to all relievers if it is valid.

If so: is his save percentage greater than 93% with 10 or more opportunities. If “yes” then “hold.” If “no” proceed to step 2.

2. Is his strikeout rate (K/9) above 7.0?

3. Is his strikeout-to-walk (K/BB) rate above 2.5?

4. Is his BaseballHQ BPV above 80?

If the answer to conditions 2-4 is yes, then CIA predicts he’ll keep the job. If the answer is no to any one of the conditions, it predicts he’ll lose the job.
