Weekly DRS Update (Defensive Stats Thru Jun 13, 2010)

June 13, 2010 DRS Year to Date.

There aren’t any changes from last week with respect to the top and bottom fielders.  I suppose that’s good - a lack of volatility. 

Last week, Russ noted the poor ranking of Pittsburgh, and Mike Emeigh has noted some Pittsburgh oddness before.  I don’t see any reason why the park *would* have those oddities, or have a strong park factor.  Perhaps Colin or MGL or AROM (or some other person studying that) can chime in on what they see in Pittsburgh, because those guys are really stinking it up.

Thoughts, comments or questions?

This week in defense.

Thanks Chris.

Are you extracting the data from PBP data or working with a dataset provided for you? Because the first thing I'd be looking at is home ZR versus the ZR of visiting fielders in Pittsburgh. If there's a park effect in any position it might show up this way.

Jason Giambi has played just 89 innings at first base, but that's good for negative three runs, and is enough to move the Rockies' defense from positive to negative. The only other NLer I can find who does more destruction in fewer innings is Jeff Keppinger, who is -4 in 87 innings at shortstop. But at least he plays a key defensive position. How is it possible for one man to be that bad playing first base?

Pretty easy if you don't go after any grounders at all, and just stand there to receive throws. On the plus side, he can scoop throws decently. Or at least he used to be able to, haven't seen him recently.

The number that jumped out at me was Howie Kendrick. -13 runs in 558 innings. Geeze.

Also Jeter. -11 in 506 innings.

I know a lot of people say the Yankees use odd infield positioning, do the Angels do anything bizarre on the infield?
   6. AROM Posted: June 15, 2010 at 04:36 AM (#3559448)
Howie's had a crap year in the field. He used to be decent. He better start fielding ground balls or else the idea of Kevin Frandsen, starting 2B, keeping the job warm for Alexi Amarista will sound like a good idea.
   7. Dan Posted: June 15, 2010 at 04:43 AM (#3559451)
Looking more at Kendrick, Plus/Minus has him at -9 runs and UZR has him at -8.8. So the other stats don't have him quite as bad, but still as a seriously bad fielder.

Young and Church are contributing nicely in RF in Pitt too. :-)

Could you double-check Roger Bernadina, Chris? I think he's got too many innings. It may explain the big discrepancy between his ranking in DRS and in UZR.
   10. AROM Posted: June 15, 2010 at 12:07 PM (#3559523)
Ron J, it does not come from a PBP dataset, well, at least the PBP dataset behind it is not publicly available. CNNSI has zone rating on it's pages, they list a player's zone rating and number of chances. Chris downloads all of this with a spreadsheet with web queries. Then you just need to add up the players to get the league total, and convert to runs.

To get home/road splits you'd need to download the data every day, then subtract the previos day totals to get the most recent day stats. It is possible but would require someone with a lot of time on their hands.

What AROM said.

fra, i make a pivot table, so it'd be very strange if he has too many innings.

Dan, i expect that Jeter and Kendrick will effectively stabilize there. They may improve. BIP distribution is still very impactful at this point in the season, and many will tell you it stays that way throughout the season. We're having an in-depth conversation related to this at The Book Blog. Join in.

#10/11 I know I can automate the download so it's done daily. James Weisberg and I discussed doing this a decade ago and the chance to get home/road ZR splits was one of the reasons we wanted to do this. We'd also be able to look at individual pitcher ZR (or at least ZR in pitcher's start, which isn't perfect but rates to be interesting)

Won't happen until I get my new system -- which should be Real Soon Now.

Frenchy at +4 in RF is pretty solid, it's a pity they probably won't platoon him and Pagan when Beltran is back. Sweet jimeny is Castillo a black hole of suck at 2B.

You're right. Sorry, I'm getting used to new spectacles.

In which case I return to my original comment, which is that there is a considerable discrepancy in runs between UZR and DRS on Roger Bernadina, which is interesting; but now I've forgotten what else I was going to say about it.

Well, we know which one is "right". <wink>
