The Disabled List

Medical Sabermetrics

MAJOR NEWS UPDATE:

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...

  • BRADSBEARD: Javier Assad was still pitching into the 6th inning, and the first batter he faced reached base on an E-4 (that was Assad's 70th and final pitch of the game). Then Leathersich relieved Assad and retired the second batter 4-3 on the first pitch of the AB (the runner at 1st base advanced to 2nd on the play), and then on an 0-1 pitch the third batter in the inning (second one faced by Leathersich) lined into an inning-ending 6-4 DP (baserunner doubled off 2nd base). When calculating GO/AO, double plays and triple plays count as only one out.

  • Wow. The site actually loaded without an error! Happy 4th all, and Go Cubs!

  • OK -- my 4th of July resolution is to try to stay more positive. So -- 10 games to the AS break, meaning the Cubs will be in first place at the break! First time since...2008? Also, hopefully, Willson, KB and Javy learned something about Familia yesterday that they can use in the future.

  • Hmmm, my math might be fuzzy but if he retired 3 batters with 3 pitches, how did he get a 1/1 GO/AO ratio?

  • Pls DFA Peralta when Richard comes back. Richard 1 IP, O R, O ER, 0 BB, 2 Ks in first rehab appearance. We really need to trade for a LHRP.

  • "The Boston Red Sox were banned from signing any international players for the next year and had five of their teenage prospects declared free agents on Friday after a Major League Baseball investigation showed they circumvented signing-bonus rules last year, a source familiar with the situation told Yahoo Sports."

  • The thing with Heyward is its not just free agency. He is way under performing his career #s. He's making the same % of contact but his soft contact is much higher and hard contact much lower than all his previous years so there is something very specifically going on this year causing the issues. Chances are he will eventually get back to his previous #s and it's better to get the slump now and get that hot run later but I wish I knew what is different about this year. He's either just not seeing the ball as well or a swing change is causing it.

  • Only 3 pitches for Leathersich. Not much of a rehab outing.

    Thanks for the reporting Phil.

  • He's the nastiest pitcher I've seen in awhile. I'm gonna give them all a mulligan on this one.

    Coghlan's strike out was more disappointing. He was fighting off a lot of pitches and not swinging at crap, and on the last pitch, he swung at stuff he was laying off, and struck out.

    And Heyward, too. I don't blame Heyward - I blame free agency. I hate it. You almost never get a valid return on the investment.

    I look forward to the day when ball players own the teams. The current economics are not sustainable.

  • Oh, I'm sure you're right. He's not 27-27 in saves for nothing. But, man, I hope they learned last night that he didn't throw a single pitch in the zone to KB, Contreras or Baez, and they all just kept swinging.

  • Sounds like a much better game than last night's fiasco in Flushing.

  • I'm pretty sure it looks like a sweet pitch on the way in. How many sinkers like that are there at 98 mph? I agree that they should just do a Lackey and stand their with their bat on their shoulders until he throws a strike next time, but I can see how that's hard to do.

    The bullpen, on the other hand, is a mess, and Heyward is starting to piss me off.
