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...

  • My unsolicited opinions on topics covered in this thread:
    1. I hate the fact that after 162 games, a team could be out after 1 game. However, I think the system is pretty close to perfect right now. 2 of 3 isn't feasible unless they shorten the regular season, and it ices the division winners for way too long. This creates excitement, and rewards the division winners.

  • Personally, I think the game could have had a very different look had the Pirates held onto the ball and tagged Fowler out on the steal in the first. Cole was clearly frazzled, but if they took that runner off the base, it could have relaxed him a lot.

  • Football games are played once a week. There are 16 games a year. I'm not even remotely following at all how you can compare the two leagues and playoff systems. It is physically impossible to play a home and away series. The idea of not having any road games in baseball playoffs is certainly a head scratcher.

    How is not having the first and last game at home a benefit for the division winners and team with the best record? How is it not an incentive to win the division when a WC team has to blow their top pitcher?

    Call me lost.

  • Two 97+ win teams in a do-or-die, great bullpens, overpowering starters, plenty of pop--hard to believe that game wouldn't be tense. A 4-0 lead is not a blowout, especially in that situation and with the Cubs' young bullpen. Not only would a defensive play here or there make a difference, but you get the win there also on the home plate umps strike zone (generous strike calls for Arrieta, including a couple Ks), and on Schwarber sitting on the right pitch at the right time.

  • Unbeleivable Dodgers:
    I just noticed the Dodger's payroll today. It is just absurd. $300,000,000+!!
    Here is where just some of their money is for 2015:

    Some "Highlights"
    Carl Crawford $20MM
    Brandon McCarthy $17MM
    Bronson Arroyo $3.5MM
    Darwin B $2.2MM
    Dan Haren $10MM
    Matt Kemp $18MM
    Brian Wilson $10MM
    Ryan Webb $2.2MM
    Dee Gordon $2.5MM

  • So I think tomorrow will be the most important test of how far we can go. We can win it all with two pitchers since Arietta has shown he can carry over his success to the post season. If Lester can be dominant also then I think we can go far no matter how Hendricks or Hammel do.


    And in terms of pitching just went through to see how we could maximize Lester and Arietta and came up with this (Lester would be going on 4 days rest three times and Arietta twice):

  • i still can't believe that crawford contract (7/142). all that loot and years for a LF'r who's entire hitting game revolves around his legs and line-drive power. those triples that raised his value are deceptive as hell to his true power, but it helped him get paid.

    there's also pause about a guy who's ob% is almost totally driven by hits rather than walks. BOS got lucky unloading that crap deal.

  • I think the Cubs take Berry and Soler off playoff roster and add Hammel & Ramirez. Believe Maddon will find Denorfia & Jackson defense too hard to lose.

  • O & B: I like the one-game Wild Card heart attack game, but I'd actually like to see a best two-out-of-three LDS played in the home parks of the two division winners with the best records, and then the LCS as a best two-out-of-three in the home park of the division winner left standing with the best record, and then let's get to the World Series already. 

  • I...don't know. If chanting would help the Cubs beat the Cardinals in the next series or ultimately the World Series I think I'd be ok with it lol. I'm not supportive of saying insulting things to opposing fans or throwing things but loud noise and chanting seems appropriate to me.

    I also grew up in France though and that kind of thing is par for the course at soccer and rugby matches and I love it. I find crowds too passive here.

  • Er, they won the first one. My bad. Carry on.

  • With last night's win in Pittsburgh, the Cubs have tied the Pirates with 98 wins, and are only 2-1/2 games behind the Cardinals. No reason why the Cubs can't finish the post-season with the best winning percentage in baseball (regular season & post-season combined). 

  • BOB: I doubt very much that Matt Szczur will be on the Cubs LDS roster.

    If he wasn't on the Wild Card roster (when the Cubs went with 15 position players), he won't be on the LDS roster (when the Cubs will go with 13 or 14 position players).

    As it is, at least one of the three RH hitting outfielders who were on the Cubs WC roster (Denorfia, Jackson, and Soler) could get bumped off the LDS roster (probably Soler).

  • I want my baseball team to win by playing better baseball. I don't want umps, fields, or fans to have anything to do with it.
