Joe Maddon is Using J.P. Howell Correctly

I've beaten the tar out of J.P. Howell being used in the highest leveraged situations and Joe Maddon is really doing a brilliant job of doing just that since Troy Percival finally broke. Howell has appeared in 15 games the last 30 days, which dates back to when Percival was still pitching, and his average leverage index is 2.14; Percival's in those two games was 2.52.  Howell's average pLI with Percival around was 1.21, and without is 2.18. Let's take a look at when Maddon is using Howell:

@ FLA entered bottom 7th, ---, 0 out, ahead two, 2.91 aLI
@ FLA entered bottom 9th, ---, 0 out, tied, 1.89 aLI
@ CLE entered bottom 7th, ---, 0 out, down one, 0.53 aLI
MIN  entered top 8th, --3, 0 out, ahead three, 2.35 aLI
MIN entered top 9th, 1-3, 1 out, down one, 1.71 aLI
KCR entered top 9, ---, 0 out, ahead four, 0.21 aLI
KCR entered top 9th, ---, 0 out, ahead one, 2.22 aLI
@ NYY entered bottom 8th, 1--, 1 out, ahead one, 4.62 aLI
@ NYY entered bottom 8th, 123, 1 out, ahead two, 3.88 aLI
LAA top 9th, ---, 0 out, down one, 0.66 aLI
WSN entered top 8th, --3, 2 outs, tied, 2.74 aLI
WSN entered top 9th, ---, 0 out, ahead one,2.38 aLI

That's 15 appearances, two save chances, a 1.73 FIP, and the highest leverage on the team during that time. Maddon's not using Howell as a closer at all, he's using him as a relief ace, a fireman, the iceman, whatever you want to label him, Maddon is using him perfectly. Seriously. He could've easily said he was giving the set closers job to Jason Isringhausen or Dan Wheeler and most people would've bought into it, instead Maddon has done something far, far savvier and the Rays are a better team because of it.

Fantastic job, Joe.

Better bullpen management = better bullpen results

Who woulda thought?

Bottom of 7 no on no out levergae

Down 1 i is a .53
while up two in the bottom of the 7th is 2.91

The cost of giving up an additional run is greater down 1 than up 2 no?

at least much closer

Still, there are some unusual findings on the actual leverage table

For example:
Bottom of 7 runner on 3rd no outs

The leverage index for a 1 run deficit is 2.0, while the leverage for a 2 run deficit is 2.2. I’m in the middle of reading the Book now so I’m sure I’ll understand better in a week or so.

Average Leverage Index

I’m new to all of this and was hoping someone might provide some insight into how the aLI is calculated. I find the NY set interesting because they are both similar situations; tying run on first or tying run on second with the go-ahead run on first.

Just trying to learn—thanks for any help.

Based on this site and people’s comments and references, I’ve looked into purchasing “The Hidden Game of Baseball” and “The Book”—any other suggestions. BTW great reference—very helpful

When comparing figures like tRA or FIP

What is the minimum amount of innings in one season to make that figure reliable? I’m trying to some analysis and obviously I want to toss out pitchers that barely threw any innings, but I’m not sure what the proper benchmark should be.

by matthan on Jun 16, 2009 10:38 AM EDT reply actions   0 recs

Thanks. I'm using 30 IP.

I wish I could use more but that would kill my sample in a couple different ways. I’m trying to determine Hickeys influence.

by matthan on Jun 16, 2009 1:29 PM EDT up reply actions   0 recs

Are you just doing starters or relievers?

If it’s the former, 30-40 makes sense, the latter, I’d still try and stick with 20-30.

Both. I’m going to look at it separates but probably end up combining all pitchers. I’m not focused on the mean, but rather year over year changes for each pitcher. I want to find if the change is significant. So it doesn’t really matter if the pitcher was a starter or a reliever. Although switching from a starter to a reliever (or vice versa) would be a bad thing for this analysis since relieving is easier than starting and that variable would explain the increase or the decrease. The first way I am looking at it is whether there is a difference between a year with Hickey and a year without Hickey immediately before or after it. Then I’m going to also take a look at whether pitchers improve or get worse while under at least two years of Hickey. I’m hoping the sample is large enough to eliminate the impact of say age (e.g. Garza’s increase v Wheelers decline). Of course with this there is also survivorship bias which is partially why a high IP is needed.

by matthan on Jun 16, 2009 2:12 PM EDT up reply actions   0 recs

In other words

I’m looking at say Roger Clemens w/o Hickey in 2004 and comparing it to w/ Hickey in 2005 and also Roger Clemens w/o Hickey in 2007 and comparing it to w/ Hickey in 2006. And say Brian Stokes in 2008 w/o Hickey and 2007 w/ Hickey. Even though one is a starter and one is a reliever it shouldn’t matter since the expectation is that pitching coaches do no matter and that their metrics should stay the same.

I'm not sure you'll find much.

But if you do go through, I don’t know if Roger Clemens is the best measuring stick for a pitching coach.

by R.J. Anderson on Jun 16, 2009 2:21 PM EDT up reply actions   0 recs

Actually...

Clemens had better years in 2005 and 2006 with Hickey than he did w/o him in 2004 and 2007.

by matthan on Jun 16, 2009 2:28 PM EDT up reply actions   0 recs

Of course that could be attributed to a different variable rather than Hickey, but that is why the same is far larger than 2.

And yes I know you were being sarcastic. It is obvious that his roid raging wife is the one that broke him.

sample

God I’m the worst typer when I’m at work

by matthan on Jun 16, 2009 2:33 PM EDT up reply actions   0 recs

You can’t pick and choose the data though. Something like this requires very diverse data. The larger the set the more able I’ll be able to dismiss things like age, talent, injuries, roids, etc.

If we just wanted to look at their impact on young pitchers it would require a sample size of young guns that would be nearly impossible to get.

by matthan on Jun 16, 2009 2:27 PM EDT up reply actions   0 recs

But I do agree with you that I don't expect to find much

I really don’t expect there to be a significant difference between the performance of a year with Hickey and a year without it for the same group of pitchers.But there is really only one way to find out.

I’ll finish it up between Neimann pitches.

by Sandy Kazmir on Jun 16, 2009 3:55 PM EDT up reply actions   1 recs

I just finished up

There is a statistically significant difference between a year (30IP or more) under Hickey and a year (30IP or more) under a different pitching coach in back to back years (Hickey/NonHick, NonHick/Hick). The FIPs of the pitchers go down when they are under another pitching coach. There is no statistically significant relationship for K/9, BB/9, K/9, or ERA (what a horrible metric). I’m going to throw in tRA when I have time. I also want to see how pitchers do over multiple years with Hickey. I’m not sure if I’ll make a fanpost now or wait until I get everything done.

What's Howell's vs. Balfour's?

Considering all the close games, it would have been tough for Howell not to be in high leverage spots.

by tallyray on Jun 16, 2009 11:10 AM EDT reply actions   0 recs

Last 30 days:

Balfour is up to 1.05

Traditional roles

don’t always fit best with certain players or certain teams. Perfect example.

One problem.

I have JP on my fantasy team. Quit being selfish Joe. You’re personal mission is hurting my team.
