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...
The raw data:
|•3,072 players were placed on the disabled list from the 2002 season through 2008, an average of 438.9 per year.|
•The high during the period was 516 in 2008, and the low was 388 in 2005.
The major findings: Arms>Legs>Backs>Core (ribs/abdomenals)
|•51.4% of all injuries during the period were to the upper extremities.|
|•30.6% were to lower extremities.|
|•7.4% were back injuries.|
|•4.3% were injuries to core muscles.|
Next finding, pitchers are fragile: D'oh, but impressive considering there is an 8:1 ratio of fielders:pitchers during games. Of course some injuries don't happen during games (see Clint Barmes inury). I'd love to see stats for catchers or a breakdown of fielders who get injured batting or baserunning. The catcher data was apparently, not in the study. The batting/baserunning data would take a little more research outside of a DL list.
|•Pitchers spent a greater proportion of days on the disability list, 62.4%, compared to 37.6% for fielders.|
The obvious is verified, but now it's quantified: Pitchers tend to hurt their arms!
|•Pitchers accounted for 67% of upper extremity injuries, compared to
fielders, who had more lower extremity injuries and injuries to other
|•Fielders had a greater proportion of lower extremity injures, 47.5% compared to 16.9% for pitchers.|
NL vs AL: Identical patterns.
|•National League players injured their upper extremities 51.7 percent of
the time, lower extremities 30.7 percent and other anatomic regions 17.7
|•American League players injured their upper extremities 51.1 percent of
the time, lower extremities 30.5 percent and other anatomic regions 18.4
percent, according to the study.
Timing of Injury: Mostly before the All-Star Break (74.4%)
|•79% of shoulder and elbow injuries happened before the All-Star Break|
|•74.8% of the other injuries (groin, hamstrings, quads, trunk/core)
before the A-S game.
|•Pitchers sustained 76.5% and fielders sustained 71.7% of their total respective injuries prior to the All-Star game.|
I just might be crazy enough to build on Dr. Posner's work and do a Cub specific review of that readily available DL data (sounds like an off season project...although this entire season has been an off-season). That should be interesting in light of these published league norms to compare to.
I have followed Baseball Prospectus' Will Carroll epidemiologic (medical sabermetrics?) work. He gives out the now annual Dick Martin Award to the best team medical staff (last recipient was the Phillies, Cubs now in the top one-third!). In a previous TCR article, The Cubs Trainer vs. The Secretive Nature of the Industry, I detailed the Cubs head trainer (yes, he works on all body parts), Mark O'Neal in the context of the BP Dick Martin award. I also wrote about the 2010 Cubs in the context of Will Carroll's health report ratings and the data that he tracks, Running a Yellow Light.
Baseball prospectus posted an excellent chart for the 2009 season, days lost to injury (sabermetrically speaking, D-LOIN?) vs salary lost, as a percentage of total team payroll (S-LOIN?).
The award is based on a number of factors, including but not limited to quantitative measures such as days lost to the DL, dollars lost to the DL, percentage of payroll lost to the DL, and year-over-year improvements and trends regarding these numbers.
Maybe that's one more thing Tom Ricketts should put on Ari Kaplan's To-Do list (Ricketts hired Kaplan as Cub manager of statistical analysis this past June).
so...what's chan-yong lim up to these days?
yes, those hamilton WAR numbers are very reasonable. i'm on your side now based on that biting commentary and reasoning of why he's a 3.5-ish WAR player over a 600 PA season.
those numbers are obviously well deserved and worthy of no scrutiny...none at all. no issue.
CF D is rarer than a jon lester pickoff at 2nd...totally irreplaceable...no way in hell there's good D, low/no-hitting CF's in anyone's system that could do what hamilton is doing. guys like this don't exist...you get like, 2-3 at any given time in history.
Please do not discuss War here. I think the Cub Reporter should be politics free.
But yes, whether you support War or Peace...Mike Trout is ridiculously consistent and good.
"According to FOX Sports' Jon Morosi, Tim Tebow's baseball workout Tuesday in Los Angeles will be attended by scouts from "roughly half" of the 30 major league teams."
"One scout told ESPN.com last week that Tebow's swing is so long it might "take out the front row." That's not a good thing."

The #MBpelicans and @Cubs have extended their PDC through 2020!
Carolina League getting 2 new teams too.
CF WAR is ridiculous...billy hamilton is pulling a 3.0 WAR somehow...and managed a 2.0 WAR last year (even though he missed a month of the season)...and a 3.7 WAR in 2014.
yeah, a lot depends on how one is doing relative to others at a given position, but WAR is common used (right or wrong) as a blanket comparing all kinds of players.
trout's one of the best, and at this point should probably win over donaldson (and should have more MVPs in the past, too), but the defensive aspect of valuing WAR still needs more tweaking...imo.
Mike Trout is ridiculous
Don't know if Cubs will recover from "spanking" Gordo
2nd in defensive WAR, NL.
6th in NL in RBI
Go complain about something else, like, "they never play good against the good teams", or some other shit.
Addy really has trouble breaking through .250 BA -- after his hot streak got him to .251, he has gone 1-for-17.
Thank goodness for Jansen's 2 WP on Friday -- otherwise this would have been a sweep.
There seems to be a direct correlation with overconfidence in the Cubs offense against mediocre/young pitchers and really poor offense against mediocre/young pitchers. So, let's fear the Pirate pitchers!
Rizzo due for a power surge -- one HR in August so far. He truly does hit them in bunches.
Sometimes I'm not as supportive of Cahill as maybe I should be. There, I said it.
Rough 8th inning all around -- HBP, Cahill error, Javy's poor decision.
Oh well - given that the Cubs didn't look like they were going to score, it's better to lose in 9 innings, save the bullpen and get changed for the PJ trip home.
