rolling sabermetrics and statistics thread

because i'm tired of all the outdated annual threads on this board. baseball prospectus has a new pitching metric, SIERA, and you can read all about it for free in these five articles:

tom tango and matt swartz (one of the two guys who came up with this) have a LENGTHY exchange about it here that i'm still working my way through:

i am not even close to comprehending of a lot of the math involved but their explanation of the stat is pretty readable. if it works, it's probably some of the most interesting stuff bpro has done in a while.

Could you ever see a team going completely by the numbers? That is to say, being an "every day player" would be meaningless because the team would play the statistical matchups every day no matter what in an effort to maximize output.

You mean like Casey Stengel in the 1950s? No, I don't see that happening anytime soon. Too many relievers on the roster, too many guys who would be unhappy with irregular playing time.

not really SABR but interesting stat:

Through the first 1/3 of the 2010 season, the AL East has four of the best five records in the league.

If the season were to end today, there would be 2 teams in the AL East NOT advancing to the playoffs despite better records than all but one other team in the league.

Tampa, Yanquis, Toronto and Boston are all on pace for 90-win seasons.

I'll post this here, even though it has partly to do with some back-and-forth on the Pujols thread. Bear with me--and when you jump all over me, please remember that I bought my first Zander Hollander guide in 1970. I've been there and back, and back again.

There's a blogger in San Francisco I read, Steve Rubio (a Prospectus writer when it was still fairly new, I think), and the other day he linked to the following from Jennifer Doyle, who seems to mostly write about soccer. I love what she says, and she captures some of my own feelings when I get into old-vs.-new-stat discussions on this board:

"Beware of sports writers who pretend to mastery of the facts. I come across a different version of these people in academia--they can recite a bunch of dates, or quote Hegel, and for this reason they seem to think that they've figured it all out. The ones who listen, however, who have a good sense of humor and know how to hold contradiction in their head without trying to resolve it--those are the ones who are most likely to say something interesting, something insightful, something new...Reader, beware of the sense of mastery which comes at the cost of a sense of wonder."

I have no problem at all with VORP and WAR and the like, as long as you view them as just more pieces of the puzzle. But I sometimes get the feeling that when someone throws VORP at me, it's like when someone yells "Challops!" on ILM, or "Muslim!" in Palin World--it's meant to end the discussion, not add to it. Obviously, we're a million miles ahead of the days when people used to think Steve Garvey was the best hitter in baseball because he'd go bat 700 times and knock in 100 runs. (Pointing out, however, that even James revised his thinking on Garvey when he reissued the Historical Abstract--one of many reasons I like James so much more than his disciples.) I wouldn't want baseball arguments to return to that level of thinking. But to echo Doyle's last sentence above, if your belief in the infallibility of VORP and WAR lead you to shrug your shoulders at the prospect of Pujols or Votto winning the Triple Crown, that's a place I don't want to end up.

I'll have more to say on this in my upcoming book, VORP: The God That Failed.

haven't you heard, the triple crown is now comprised of VORP, WAR, and WPA/LI

clemenza, Thursday, 26 August 2010 18:46 (eight years ago) Permalink

win probability added divided by leverage index

it's generally about the same as the batting component of WAR though, so not very useful. plain WPA is more interesting and kind of like the sabermetric equivalent of RBIs.

ciderpress, Thursday, 26 August 2010 18:49 (eight years ago) Permalink

Thanks. I'm dying to find out what Ray Oyler's Leverage Index was for 1969--not very good, I'm guessing.

clemenza, Thursday, 26 August 2010 18:52 (eight years ago) Permalink

clemenza otm. James revolutionized my thinking during the mid/late 80s, but my enthusiasm for the game waned in the 90s when it seemed like the New Math was press-ganged into service to fantasy baseball. In the late 90s I sort of got my mojo back by actually watching a lot of baseball instead of reading about a lot of baseball. Sabermetrics are good corrective lenses, but I had to remember to use them to watch baseball games, not read box scores. I get a lot more fun out of the game that way.

leverage index is just a value which quantifies how "important" any single plate appearance is to winning that game

so bases loaded, 2 outs in a tie game would have a really high value whereas bases empty in a blowout would be really low

ciderpress, Thursday, 26 August 2010 18:59 (eight years ago) Permalink

Has a leverage index been developed for relief appearances? Inherited runners stranded/scored drives me bananas.

Andy K, Thursday, 26 August 2010 19:01 (eight years ago) Permalink

Admission I'd rather not make: I'm still stuck in a place where I follow baseball primarily through the lens of statistics (more traditional statistics, but statistics nonetheless). Getting back to actually watching more baseball is my next therapeutic goal. (Part of this does have to do with the overload of baseball on TV. Somewhere along the way, it just became too much.)

clemenza, Thursday, 26 August 2010 19:02 (eight years ago) Permalink

well yeah it works both ways

if a game situation is a 1.5 LI for the hitter (1.0 is average) then it's a 1.5 for the pitcher too by definition

ciderpress, Thursday, 26 August 2010 19:03 (eight years ago) Permalink

tbh i'm a math nerd and i love all the baseball stats stuff but i think sabermetrics folks tend to have too much confidence in their own metrics, there's not nearly enough self-evaluation in the "field".

i think the offense stats are pretty close to complete but there's still so much we don't understand about pitching, let alone defense or player development

ciderpress, Thursday, 26 August 2010 19:06 (eight years ago) Permalink

I think there is plenty of self-evaluation in the field; the BP guys debate stuff all the time, and most if not all recognize that these metrics are imperfect tools.

(not that I have the time to read all the articles or watch a game every day, understand)

Agreed. And just to really horrify VORP disciples, I think you can even learn something from Joe Morgan when it comes to "in the field" stuff. I realize Morgan is considered a human punchline by most everyone who's been influenced by James, but if you can look past the many blind spots that someone of his generation probably carries around (having to do with character, clutch play, the value of a .300 average in and of itself, etc.), there are going to be some things that he's learned about the game that I just don't believe you can arrive at through abstract statistical analysis. So treat him skeptically, for sure, but don't try to ridicule him out of extistence. (When the influence of James on me was at its peak in the late '80s/early '90s, Kubek used to drive me up the wall for the same reasons.)

Morgan does not deserve to have the most prestigious color commentary job for baseball in the world. That doesn't mean he's never insightful. But the fact that he has insights into baseball is meaningless. He lacks the ability to express those insights or the work ethic to learn about the teams he's watching. Orel Hershiser is a far better analyst. Keith Hernandez is another guy I've enjoyed. Neither of those guys is a stats guy, but both actually do the legwork to bring some on-the-field insight to the presentation.

Also, while I have my issues with Morgan, there are plenty of guys who are worse. Rob Dibble springs to mind.

Which reminds me, John Smoltz has been an absolute treat this year since he sorta retired.

Keith Hernandez is listenable mostly for the crazy shit he comes out with. He calls Jeff Francoeur "a streaky hitter."

kind of shrill and very self-righteous (Dr Morbius), Thursday, 26 August 2010 19:38 (eight years ago) Permalink

I probably haven't listened closely enough to Morgan to be defending him. The back-and-forth between Miller and him is easy enough on my ears that I've never quite understood the intensely negative feelings about him that I keep encountering, but maybe that's all credit to Miller. And I have the additional bias that the mid-'70s Reds were my favourite team. This goes back a ways, but I used to think Palmer, Seaver, and Reggie were great in the booth. As analysts, I can't remember. I just liked them.

clemenza, Thursday, 26 August 2010 19:39 (eight years ago) Permalink

to clemenza, i don't know dude, you seemed pretty "blinders-on" when discussing Bonds' achievements and were in the process of pooh-poohing him on the Pujols thread so........... idk, was tbh hard to take you seriously in your short shrift dismissal of him as a legit triple crown candidate given the 232 BBs that got in the way of him chasing such a "retro-cool" counting achievement (all the while destroying almost every offensive record in the process).

but kudos to all y'all who were reading bill james in the summer of love~~~

i don't mind Morgan and Miller, because they're both local guys. Morgan seems way worse on the page then in the booth ime.

ciderpress, Thursday, 26 August 2010 19:49 (eight years ago) Permalink

Steroids notwithstanding, I really wasn't discounting the magnitude of Bonds's statistical achievements--just that I thought the walks ruled out him ever having a realistic shot at the Triple Crown. Not just in terms of RBI, but, I thought, also in BA. But Ciderpress's math made me realize that he in fact likely would have won one, maybe even two. Which was your point to begin with--you were right, I was wrong. What I didn't appreciate, though, was pulling out VORP as kind of a gotcha moment, like I'd just been teleported out a 1974 issue of Baseball Digest. (Not to knock BD, which I used to love.) Again, I've been reading James forever.

clemenza, Thursday, 26 August 2010 19:58 (eight years ago) Permalink

That's cool, just like I said, you appeared to be full blinders in your take on Bonds achievements.

Also, VORP was introduced 9 years ago by Keith Woolner. Bill James has always preferred win-shares and runs-created in my 10 years of being familiar with SABR. IIRC.

i liked this little bit from the pitchFX summary on bpro:

5:39: Brad Hawpe play: starts with a >80% chance of catching the ball, but freezes in place and fails to make the play. Difficult to represent visually, because the out probability plummets while Hawpe stands in place and time elapses. In a different Hawpe play, his first step gives him a lower probability of catching the ball, since he broke in the wrong direction. Rumor has it no Rockies reps are in attendance, but they’re not missing out, since they’ve enjoyed a front-row seat for this sort of action for the last several years.

Not sure if there would be an article out there on that but I’m interested in analysis about players who lose their ability or perhaps willingness to draw a walk as they age. Specifically thinking about someone like Albert Pujols, and whether or not it has mostly to do with pitchers challenging him more as his skills erode, thereby not pitching around him anymore + not IBBing him nearly as much (if ever!) I’m interested primarily bc of the many aging players who either retain those skills or sometimes even improve them over time (one example: Willie Mays drawing a career-best 112 walks in his age 40 season.)

My guess is there’s a lot related to bat speed and players having to cheat a bit more, which means they’re simply not going to be able to wait that extra split second anymore. But it’s interesting to me how some players completely lose a skill that seems to be one that would age well (and often and perhaps usually does!)

omar little, Sunday, 17 June 2018 20:17 (seven months ago) Permalink

i think with pujols specifically it's that pitchers aren't afraid to challenge him anymore. same with the ghost of chris davis. i'm not so sure that they necessarily had a walk 'skill' so much as it was a by-product of their other skills

curtis granderson, on the other hand, has seen his walk rate go up even as his power fades. it is intersting

Got curious so searched for baseball's best inning-eaters and came across these numbers on a fantasy baseball site.

Starters throwing a heavyweight innings workload over a season are a declining breed. The number of starters pitching at least 180 innings has dropped year-on-year.

2014: 66 starters
2015: 56 starters
2016: 45 starters
2017: 35 starters

The trend is dramatic, and although it is unlikely to fall by another 10 this season, it is also unlikely to increase. So in 2018, there are only likely to be 30-35 heavyweight starters.

Looking up the top innings pitched numbers in MLB, there is a decent chance that the number might not hit 30 starters throwing 180 innings.

From Day 1 of Saberseminar... BP has a new stat for you!

The highlight of the morning, however, did not focus as much on pitching. Instead it was a presentation by Jonathon Judge on a companion stat to DERA, Deserved Runs Created. DRC should appear on Baseball Prospectus in the next couple of weeks. And, it promises to be one of the best comprehensive hitting stats for overall offensive output. In particular, the DRC+ version (adjusted for parks) looks to be particularly useful. Judge was also quick to back up the data by showing the reliability of the stat for players switching teams as compared with alternative measures such as wOBA or wRC+.

I check the WAR leaderboard on Baseball Reference every two or three days, mostly with an eye towards the awards. Something I will never understand (i.e., not the first time I've encountered this): Scherzer's dropped by 0.3 from a couple of days ago without making a start.

Is it possible that it's a case of the R in WAR getting better?

I think I mentioned that as a possible explanation when I brought this up a few years ago. But the replacement level changing by a third of a win in a couple of days seems like a pretty wild swing.

Wonder if the replacement level calculation gets updated every so often rather than changing automatically.

could be other things getting updated, too, like park factors? i'm not sure. if the replacement level for calculation for pitchers was updated, wouldn't that affect all pitchers WAR?

Maybe on days when you're not playing, they factor in intangibles. Were you offering your teammates moral support from the bench, or did you spend the game in the clubhouse getting a massage? Were you out there for yesterday's bench-clearing brawl? Did you make yourself available for autographs before the game, or did you tell some seven-year old to take a hike?

useful link for the future:

the first image is the good old run expectancy chart, broken out by pitch counts:

the second is the same data presented in a different way, relative to the 0-0 count. it took me a second to figure out wtf was going on, but you start with the number of outs and the position of the runners on base. then move to the 0-0 column. from there, it tells you how every subsequent pitch to that batter affects the run expectancy.

Quite interesting:

Was Jack Kralick the best pitcher in the American League in 1961? WAR says yes (bWAR, anyway), James says "Are you kidding?"
