The Disabled List

Medical Sabermetrics


Lou Piniella will resign after today's game vs Atlanta. His mother's health has not improved and instead of going the medical leave of absence route again, he's handing over the managerial chores to...THE FORMER IOWA CUB MANAGER... drumroll, please...[[[Mike Quade]]]. Pfffft.

There is a segment of the news reporters who actually cover medical meetings and try their hand at using medical lingo on their readers. I found this article online (and several other sources picked it up including the LA Times) but it originates from a news feed that the American Orthopaedic Society for Sports Medicine provided after their 2010 annual meeting from Providence, RI.

This is clearly an epidemiologic study. I'm thinking medical sabermetrics is a better term.

The study was based on data from MLB's disabled list published online data from 2002-2008, so it didn't really need a doctor to do this, it probably was done by a doctor who is a baseball junkie. Hmmm.

Dr. (and Major) Matthew Posner took the raw information and tabulated the frequency and distribution of injuries by anatomic site, position, AL vs NL and time of season (before or after the All-Star break). Nicely done. Clean and simple.

"Even though baseball is a passion of many people and our national pastime, there is very little information about the epidemiology, characteristics or distribution of injuries in Major League Baseball,” said Maj., Matthew Posner, MD, orthopaedic surgeon at the William Beaumont Army Medical Center in El Paso, Texas. “This study attempts to evaluate Major League injuries over the period of six years.”

On to Dr. Posner's findings after the jump...

  • has some interesting stats/graphs on pitch and strike zones and you can dial up individual games/pitchers. I'd love to see some comments from readers who can interpret this better than I can. I thought the Ump was really inconsistent with a very wide zone. Does this info seem to match up with my eyeball perception?

    Here is Lackey/Lester from last night. It seems their box is a bit different than the K-Zone TBS was using.

    Here is Lester's data:

  • AZ Phil: Agree, this must have been a really fun game to watch. There was a lot of base stealing going on. Are the pitchers not holding runners or is the catching still a work in progress?

  • Cuzzi has long been known as having the biggest strike zone among all umpires.

  • AZ Phil, give me a scouting report on Chris Pieters since he has become a 1B/OF.

  • I think it's probably hard to adjust to an ump's zone mid-game, as least for hitters. Pitchers can locate to an ump's zone, but hitters have minimal time to react.

    But, whatever. Umps are going to miss calls. Let's beat up on the non-Lackey starters.

  • Watched a little of Mets-Dodgers.

    Jason deGrom -- oh, my.

  • Cubs 3-4-5 hitters are 0-21 so far in the post-season.

    Let's change that in a big effin' way tomorrow, boys.

  • Considering how players reacted it seemed pretty accurate high and wide (to righties), but not so accurate low and in. I thought the strike zone by the ump was awful, but it was consistent and the Cubs never adjusted.

    Rizzo and Bryant need to have good at bats. They are really looking outclassed in these two games.

  • that game sounds fun as hell.

  • I was just wondering the same thing. I'd rather not see it at all. If it's inaccurate, it's a bad viewer experience. If it's accurate, it shows some shitty calling by the umpire.

  • TBS' K Zone seems to be more harsh than the others.

    I wonder if MLB will ask the networks to stop using them. They just make the umps, and the game, look bad, and it only pisses off the fans.

  • ...joe.

  • "Strop vs. Cardinals." Seen the movie. Hated it.

    Not all that disappointed -- I didn't think they would beat Lackey in Game 1. Need to get the bats going against the guys with less experience -- and they hit Wacha pretty good.

  • Rizzo has been slumping the last couple weeks of the season. Very disappointed it has continued during his penultimate moment of his career to date.

  • Really doesn't matter, but I was surprised to see Lester pulled and Strop pulled in. Should of left Lester in. oy.

  • Sweet merciful fuck, I hate the Cardinals.
