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).
AZ PHIL- Is Clayton Richard a free agent or not? One site I see he is, on another no. MLB has him listed as a free agent, Cot's contracts says he is a FA, baseball-reference says he's not, but Cubs have him on active roster. I know that he is just short of MLB 6 years service by just like 15 days, but that doesn't always matter.
Except that he gave up Russell and McKinney for a half-season of Hammel...
Beane cam at least point and laugh at Hammel.
The genius Angelo traded Olsen at Martzs request
Maybe Theo will sign Shark just so he can call Billy Beane and say: "Let's see...Russell? Check. McKinney? Check. Hammel? Check. Ninja? Check. Any other deals?"
To be fair to Emery and Trestman the foreshadowing of last year started happening well before them with the failure or mismanaging of multiple draft classes forcing the team to overspend in a free agency market that is even worse than baseball. Kyle Long seems like a good pick but they traded away another good one in Olson because of Martz's stupidity and inability to change his offense to fit the team talent.
HAGSAG: I think Domonic Brown does fit the criteria of a reclamation project, but unless he is willing to accept a minor league contract with an NRI to Spring Training, I don't think the Cubs would be interested given where the Cubs are right now. A couple of years ago? Yes. But probably not now.
Brown would be better-off going to a club that is rebuilding and re-establish his value there, like Chris Coghlan did with the Cubs. And if he can re-establish his value, he could get traded to a contender at the trade deadline and take it from there.
"they just fade away"
(Except in the cases of no-fade lefties like Moyer, Orosco and Rich Hill.)
Amazing to me how quickly it fell apart under Trestman. Year 1, they were a Chris Conte brain fart away from making the playoffs. Year 2 -- coach, staff and GM all fired.
I am sure Jonathon Mota will be signed next.
AZ Phil, what is your thoughts on Domonic Brown as a reclamation project?
He also played LF in deference to Curtis Granderson.
Meh... other moves to make...hope to see a move or two soon.
I haven't seen much Bears football this year - difficult to watch the games out here, but the game I saw the week before I was watching in shock as I saw them actually make tackles. And Cutler has looked really good, too.
I guess people can quibble about play calling, but the team I saw is way more than 50% better coached (my only very minor disagreement with your comment).
Under Trestman, the team didn't do anything right. This team played like a well coached team when I saw them play the Rams.
"What is sometimes overlooked about Vogelbach because of his "bad body" and because he has struggled so much defensively is that he is a hard worker, has a great attitude, loves to play the game, and is very well-liked by his teammates, and while that may not seem important, teams do actually value stuff like that. "
As well they should. Replace a word here and there and you are describing any worker someone would hire.
