BtB "Sabers" complete

2010-02-04T22:47:00.003-05:00

Today we posted the results of the final category in the BtB Sabermetric Awards. This was the first time I've tried to organize anything quite on this level in the sabermetric community, but I'm extremely pleased with how it all went. Hopefully, we can do it again next year. Here are the award result posts:

Onward to the next project! I still have this minor league thing I want to get finished, and after that it will probably be time to start working up a team projection for the Reds. I'm pleasantly optimistic right now about their chances to top 0.500 this season...

A while back, I posted a preliminary topic list for a baseball class I was working on at BtB. I've continued to add to this list and flesh it out as time as gone on. I thought I'd re-post it here as a more or less permanent storage place....at least until it becomes to unwieldy. At some point, I will try to go through and format it to be more pretty, but for now it's functional and that's about all I'm interested in.

Anyone have a good article on this? Ideally using something like Dan Fox's EqBRR? I think John Walsh might have done some speed stuff at some point along with his arms stuff...? I don't want to just do SB's, it's gotta be all baserunning.

Not sure on articles (recommendations?). Discussion would likely involve context-neutral vs. context-sensitive statistics, average vs. replacement baselines, and for hall of fame, peak vs. accumulated value. This might end up being a good way to pitch the player value discussions rather than a topic in and of themselves.

2010-01-08T10:54:00.005-05:00

I finally finished a post at Red Reporter that I've been working on for almost a month (and planning since September). I'm not sure the result is as fabulous as all of that would imply, but it's an investigation of the degree to which the Reds were hurt by playing time shortfalls in it starters compared to simply failing to perform when healthy. Punchline: aside from Volquez (who accounts for 35% of the overall ~7 WAR shortfall), mostly it was simply a failure to perform.

At BtB, I'm managing the Sabermetric Writing Awards. I thought of the basic idea for the awards while working on my baseball class (more on that in a sec). The BtB crew were very enthusiastic about it when I pitched it to them, and in the internal discussion, the idea expanded from ~3 categories to the 7 we are currently running. Nominations are going pretty well, though I think there is a bias toward stuff done over the past few months. Still, I've already seen a bunch of stuff that I had missed, and that's sort of the main point.

The baseball class, which I announced here, starts on Monday. I'm a bit anxious about it, but I think I'm about as well-prepared for it as I can be, and I'm excited to get started. I'm perhaps naively hoping that the students will follow my obsession in player valuation, but we'll see. First thing I'm going to do is have them pick the topics for the semester. It will probably be the case that this class will be the extent of what I can do baseball-wise for at least the first half of the semester. But one of my classes ends at spring break--just as spring training really gets underway--so that should help.

I also wanted to link to my post on the Hall of Fame ballot from December. It's gotten some decent play (Neyer link, for example), and apparently Sky did something similar at ESPN this week. The one guy I left off of my ballot, Dawson, is the guy who got in--but I have no problem with that. What I do have a problem with is all of the deserving individuals who should have gotten in before Dawson.

Reds Season Review

2009-12-08T22:14:00.005-05:00

Image via Wikipedia

I completed a "sabermetric" (I still don't like that word, but I've become resigned that I have to use it to be understood) review of the 2009 Cincinnati Reds at Red Reporter. Here are the parts:

Did some fun things here:

The introduction piece has a nice historical angle to it that I really like.
The position-by-position run above average plots in the position player pieces were a nice way of summarizing the overall team performance.
The hitting info included full baserunning from baseball prospectus pull park corrections, so I think it's the best available right now for Reds players.
The fielding info incorporated fan scouting data in a semi-crude, but still useful way. Again, I think it's the best available for Reds players.
I also really like the introductory graph for the pitcher piece. People can complain about one metric vs. another, but when all three approaches show the same thing, I think it paints a pretty strong picture.

Well, that's enough patting myself on the back for one day. It's exam week and I have to figure out what I'm going to do if school gets snowed out tomorrow.

BtB Power Ranking Season Reviews

2009-10-23T17:04:00.000-04:00

Earlier this week, I completed my season-by-season reviews of all MLB teams. Fun exercise. Here they are:

Here's what I wrote about the Reds:

I root for laundry of this color. It was a rough season, but after dwelling in the basement for much of August and early September, a hot-hot-hot streak at the end of the year got them up to 26th place in the rankings and 4th place in the division over the last few weeks. cW% was substantially lower than true W%: 0.441 vs. 0.481. The reason was a slight underestimate of runs scored, and a slight overestimate of runs allowed, plus the fact that even straight-up Pythagoras had the Reds as a bit lucky. This was quite possibly the best fielding team in the National League, but their pitching was just a tad below average. And that, coupled with an offense that flirted with the 0.300 wOBA line for most of the year, spelled disaster. So, for the 9th consecutive season, Reds fans are wondering if next year will be the year they finally win more than they lose again.

And here are the final 2009 Beyond the Box Score Power Rankings. I really enjoyed doing that series this year, even if occasionally was a bit contentious (:cough: Giants :cough:). Very well received, and might go even further next season if we can keep it going. Just need to figure out some strength of schedule adjustments.

Now that I'm done with that series for a while, I have some Reds work I'm planning. Look for a recap of the 2009 season at Red Reporter sometime next week if all goes well. I also have a minor league study about half written up at BtB. Stay tuned...

Barry Larkin for the Hall

2009-10-23T15:26:00.002-04:00

I finished a piece last night, running today at Red Reporter, arguing for Barry Larkin's induction into the Hall of Fame. Response has been very positive, with links from BBTF (Repoz) and Rob Neyer, among others. Everyone seems to think that Larkin should get in (as I show, that's clearly supported by the data), but some think he might have some trouble. Hopefully he'll get in before guys like Jeter start appearing on the ballot.

Regarding Mudgate: I will read from a prepared statement

2009-10-02T12:52:00.003-04:00

I did it. It's all my fault. Yes, the attendant rubbed the balls correctly and thoroughly. But I cleaned them. With soap. And a Snuggie.

I deeply regret my actions and apologise to my family, friends, and the baseball community. I will accept any consequences that MLB/Dave Duncan/Tony La Russa deem appropriate.

This concludes my statement. On the advice of my lawyer, I will not be taking questions.

Thank you.
Justin
