Team run prevention. UZR vs. FIP. Thought I'd share it with the BtB crowd.

I'm planning to update it when I get home to my newer version of excel, maybe use team logos for data markers or something.

Use ERA - FIP or FIP - ERA

It will show which teams are more likely making up or losing runs defensively

Thanks for the suggest, I’ll make an edit later tonight.

Yeah, I was going to ask why there seems to be minimal correlation.

Fips is going to zero correlation to UZR, because FIPs only looks at K, BB and HR, everything not involved with fielding

You want to look at the difference. I know the Royals ERA – FIPS is like a half a run. With the team’s D and -40, that explains quite the difference.

I was also trying to show teams that fielded well and pitched well, or vice versa. Do you think this graph was helpful in that regard?

Thanks for the feedback, guys.

I think this is the real strength of your graph, since you can see the shape of how a team prevents runs.

Yes

I prefer this to the ERA-FIP idea.

Colin has a nice post today at THT on why ERA-FIP isn’t necessarily a good way to look at those data.

I think the lack of correlation between UZR and FIP is interesting. One of the first criticisms I often hear from people about UZR as a measure of team defense is that teams with good pitching staffs can help their defense by getting batters to hit into easy outs. If that is the case, you would expect some correlation between FIP and UZR. I looked at the correlation from 2002-2008 and found it to be almost zero. We know that pitchers have limited control over balls in play so I was not expecting a strong correlation. I thought there would be some correlation though so this is interesting.
