Hanley, Panda and the Monster | FanGraphs Baseball

An interesting look at park adjustments by Tony Blengino. I have always preferred park adjustments by BIP rather than AB or PA. I would have liked to have seen their 2014 numbers translated to Fenway rather than just adjusted rate stats.

ESPN’s Dan Szymborski: Modeling Moneyball Data for Long-Term Value | Blue Hill Research (PODCAST)

Dan talks about ZiPS.

In this episode of the Enterprise Tech Cast, Blue Hill Chief Research Officer Hyoun Park and ESPN’s Dan Szymborski discuss how Dan got started in building statistical models and built the ZiPS player projection system. Anybody who wants to learn to develop an ongoing projection and forecasting system, and wants practical insights and how-to’s should listen to this podcast. Also, we stray off the enterprise path and discuss baseball free agency, including whether Pablo Sandoval is actually the right choice for the Red Sox.

The Effects of Pitch Sequencing – The Hardball Times

A nice in-depth study which confirms something we already know.

Through this study I’ve convinced myself that there is value for pitchers in being able to throw back-to-back pitches of different types that have almost identical trajectories during the initial stage of flight up to the point where the batter must make a decision of whether to commit to a swing. In both seasons studied, consecutive pitches that were close to overlapping at the swing commit point but that crossed the plate in relatively different spots generated consistently higher rates of swings and misses. In addition, the closer consecutive pitches in a plate appearance are to overlapping at the swing commit point of the trajectory, the closer they can be as they arrive to home plate and still generate these additional swings and misses.

Sabermetrics can be questioned, but do so correctly

WAR isn’t perfect. It never will be. As long as analysts acknowledge its flaws and limitations, it’s a very valuable tool.

Everything should be questioned. Without that, we remain stagnant in whatever it is we are dealing with. Dissent is how we get better, and expand our knowledge. But that dissent has to be intelligent and informed in nature, or it just becomes a pointless back-and-forth. The fact is, these numbers are a part of the game now. Every team utilizes them to some degree, and it seems those who do so to a great extent are able to find more consistent success (like John Mozoliak pictured above).

The High Risk of Free Agent Position Players - Beyond the Box Score

Overall, signing positional players to 5+ year deals has not worked out well, and teams have generally overpaid compared to market rates for Wins. Teams would be better off signing mid-tier players to fewer than five years, or spending the money on the pitching market instead. A long-term deal with a positional player free agent is unlikely to be the significant value teams hope it will be—buyer beware.

Baseball Prospectus | Baseball Therapy: Against the Grind

We know that over the course of a season, plate discipline erodes as hitters presumably get more tired. It’s hard to get enough sleep out on the road and after a while even a fun job becomes just another job. Well, if players lose plate discipline, they are probably bleeding away strikes, and that can have a significant effect on a team’s chances. Maybe there are some managers who are just better at handling the grind, and in minimizing the penalty to be paid for fatigue and boredom at the end of a long season.
...
Ideally, we could find a manager (or 12) who could actually reverse the downward trend. That is, over a season, we would actually see that the players who played under them performed a little better. While everyone else was trending downward, his players would be trending upward. At the very least, he would hold the line. It turns out that there are a few of those managers. Again, setting aside the managers who were interims or who only managed for one year in the sample, we see that Mike Matheny actually turns out to be pretty good at this, along with Cito Gaston, Bud Black, Davey Johnson, and Terry Francona.
...
There’s a certain chicken-and-egg problem that we must first deal with. One could make the case that perhaps what we’re seeing is that as the season wears on for some teams, they become involved in a pennant race, and that’s really what keeps them from trailing off. I can’t fully rule that one out. There’s also the question of whether the manager should take all the credit (or blame) for these effects. Maybe it’s the hitting coach who wears the rainbow wig. Maybe it’s an organizational thing. We know that there’s an effect, but there’s a black box around it right now. How can we encourage managers to set things up to better fight The Grind? There’s more work to do here and it’s pretty clear that the possible benefits are enormous.

Is Madison Bumgarner the World’s #1 Starting Pitcher?

The system is straightforward. When a starter makes his major league debut, he begins with 300 points. From there, his rating will go up when he pitches well (based on Game Score). His rating goes down when he pitches poorly or doesn’t pitch at all (including the offseason). Complete details of the system are available both in The Handbook and on Bill James Online.

Jerry Green: Sabremetrics leave out the winning factor

“take a look at the website Five Three Eight with its numbers-ingrained copy.”  Five Three Eight? Nate Silver hasn’t been this shortchanged since he once said I was his hero!

And if you don’t believe they gloat, take a look at the website Five Three Eight with its numbers-ingrained copy.

We are now inundated not only by numbers, but also by initials. MVP is old-fashioned. Now we have WAR, OPS, and WHIP. WAR translates into wins above replacement which translates into gobbledygook.

The Sabremetrics fanatics are cheering because Trout finally is the MVP. That award was totally deserved — this past season — because his ballclub finally finished in first place in its division. Not because he led all comers in WAR.

And the magnificent Kershaw, whose regular season started in March in Australia, pitched his ballclub into a first-place finish in its division. Fact is, the Dodgers won the NL West in a romp with the enemy San Francisco Giants panting after them.

Brand new PUP

I now have an offering for the Sabremetrics fanciers.

They should add a category — PUP.

PUP is quite simple. It stands for Performance Under Pressure.

...Nate Silver — a numbers wizard out of East Lansing — is the inventor of Five Thirty Eight, that kooky website that now collaborates with ESPN. More initials.

Silver really is brainy intelligent — and is magical in predicting the results of national elections. He’s not quite so hot in analyzing baseball and occasionally is a bit short on English grammar.

What Corey Kluber Winning the Cy Young Tells Us | FanGraphs Baseball

Corey Kluber just a won a Cy Young Award without an advantage in ERA, without an advantage in win/loss record, without name recognition and without his team making the playoffs. I’d be remiss to ignore the fact that many voters also cited his strong stretch run in the second half, but it sure seems like Corey Kluber just won a Cy Young Award largely due in part to his FIP. And despite the “old-school” reputation of the BBWAA, that’s a big step in the right direction.

New baseball rules will evolve, Torre says : Sports

La Russa mentioned this in an interview yesterday. What is Ed Lewis’ expertise? Apparently he’s a vet who plays the stocks.

La Russa’s next major move will be unveiling Arizona’s new department of analytics. To run it he’s hired Ed Lewis, who helped initiate and run Cardinals Care more than a decade ago. La Russa said that baseball’s advanced math has been an asset Arizona hasn’t utilized but he stressed that his management will only employ analytics until “the first pitch has been thrown.” Then he wants the people factor to take over.

Vanguard after the Revolution | NBC SportsWorld

“Bullshit has tremendous advantages over knowledge. Bullshit can be created as needed, on demand, without limit. Anything that happens, you can make up an explanation for why it happened. 

“There was a Kansas football game a year ago; some Texas-based football team, much better than Kansas, came to Lawrence and struggled through the first quarter — KU with, like, a 7-3 lead at the end of the first quarter. The rest of the game, KU lost, like, 37-0, or something. The announcer had an immediate explanation for it: The Texas team flew in the day before, they spent the night sleeping in a strange hotel; it takes them a while to get their feet on the ground.

“It’s pure bullshit, of course, but he was paid to say that … if it had happened the other way, and KU had lost the first quarter, 24-0, and then ‘won’ the rest of the game 17-14 (thus losing 38-17) … if that had happened, we both know that the announcer would have had an immediate explanation for why THAT had happened. … Bullshit is without limit.”

Evan Longoria: A Bust and Not a Bust | FanGraphs Fantasy Baseball

Is batted ball distance available online anywhere?

Furthermore, Longoria chased pitches outside the zone like never before. His O-Swing% jumped above 30% for the first time, and he’s been below average at making contact with those types of pitches. That might explain what led to the higher SwStk%.

So Longoria got a little swing happy at pitches outside the strike zone. But what about his power? Well, his batted ball distance which had sat in the 287 to 294 foot range over the last four seasons, declined to about 279 feet this year. That’s right around the league average. And so then it’s no surprise that his HR/FB rate also fell near the league average, barely clearing the 10% mark. And it’s not like he was hitting tons of doubles that just fell short of the wall. He went from hitting a double once every 15.7 at-bats in 2013 to just once every 24 at-bats. So this was a legitimate power outage.

Pirates must weigh risk, reward in attempt to sign Martin | TribLIVE

Some team will get very stupid this off-season with Russell Martin.

“We’re in an interesting era for age curves because of the skew of performance-enhancing drugs,” Huntington said. “We are trying to re-evaluate aging curves because they were taken way out of whack because of the influence of performance-enhancing drugs.”

BABIPf/x: A Predictive Pitch-Based Model | Community – FanGraphs Baseball

A lot of numbers in this one.

BABIPf/x correlates well to long term BABIP, better than does league average results. BABIPf/x is more predictive of next year BABIP than is previous year’s BABIP. Because batted ball results (GB, LD and FB rates) are an independent data source than is PITCHf/x categories (i.e, location, movement , etc.) these data sources could be combined to form a multi-source predictive BABIP model of better quality than either source alone. Additional work could be done to improve count, release location corrections to BABIPf/x, as well as refinement to the BABIPf/x categories.

Beaneball | Gold Gloves and Coco Crisp’s Terrible 2014 Defense

This is interesting. I’ve been looking at this stuff lately to decipher some of the season-to-season changes in DRS for players. To properly compare the defensive skillsets of players, opportunity differences need to addressed, just prorating DRS to innings is not enough.

So I don’t know. Coco caught fewer balls this year. That part is indubitable because we register one entirely objective statistic: putouts. He caught balls. He didn’t catch balls. (That, incidentally, forms a large basis of FRAA.) On the other hand, how many air balls did the A’s allow?

Year	TBF	In-play %	In-play	Air%	Air balls	IFFB%	IFFB	OFFB
2013	6069	70%	4248	59.9%	2544	16%	407	2137
2014	5971	69%	4120	53.8%	2215	14%	310	1905

(These stats are from Baseball Reference. If I knew off the top of my head where to get the raw stats, I’d just use those. Instead I have to work backward from the percentages.)

That’s not an insubstantial difference. It’s about 1.4 fewer outfield chances per game, which means 140 fewer chances to Crisp and his outfield mates in his 900 innings in center field. Breaking down the league range factors (there’s probably a better way to do this), about 40 percent of those chances would go to center, so Crisp probably saw something like 55 fewer chances over the course of the year than he did in 2013.
