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).
He's an incredible defender, base-runner and takes great AB's. A .265 BABIP is highly likely to improve next year. That being said, his power numbers are down too which is certainly concerning so I'd certainly hedge my bets with him next year, but it would be surprising if this is his new normal.
I have no deep level of expertise or analysis here, but I still like Jason Heyward. I truly wish his bat was better, but I love the defense and the feel-good nature of his signing. I might be naive, but I think his offense will improve. I'm glad he's here, and I hope he doesn't make me regret saying that!
Pay the man his money...(MVP Talk)
Kris Bryant is going to own the Cubs himself in 6 years :)
Without doing any actual research because this is the Internets, I have a feeling Bryant will break every arbitration record there ever was unless TheJedi can literally use the Force to convince him and Boras to sign a multi-year deal.
Hammel was supposed to pitch Friday, Cubs said it'll be a bullpen day instead.
Tis either a valid excuse for Hammel's recent struggles or a PR game when they try to trade him this offseason. Or possibly both
#Cubs say Jason Hammel has been pitching through elbow tightness and could have started if the team was still playing meaningful games.
Finally made it to Pittsburgh, 6 hour drive can't wait to see the game ....WTF?!?!?
Being young does have its advantages. Not that it helps Addison Russell last season.
Keith Law chat
"Nick: Speaking of players you were wrong about, do you still like the Jason Heyward contract?
Klaw: Yes, actually."
I gives player a year to get acquainted w whole Cub thing,next year will be more telling.Love the d though.
Saw Tito's comment in the last thread. Thought it was a joke.
Bubble wrap the Cubs
that's not important.
the important thing is the cubs seem to have a new defensive whizz at 2nd base according to the stats...sample size warning and all that...but i have faith in him.
imagine him having to do this 20 times a season. 6.2 innings played, 20 assists, DEFENSE GOLD!
That little switcheroo with Zobrist and Rizzo cost me 2 points in the predictions game--damn it.
We'll always have 1985. Nothing else, but we'll always have that.
Nationals 2B Daniel Murphy likely to miss rest of regular season
RVIMPENY: It's raining today so the Cubs will probably play intrasquad game(s) tomorrow and/or Saturday, but it's pretty much a day-to-day proposition, and a lot of times it's decided at the last minute.
Best bet is to check in at Riverview in the morning and ask somebody what's going on that day.
Thanks Phil, I had the Salt River chart, but based on that, it looks like they hardly play and was not on the Surprise on 9/28...I assume they do not really want fans there anyway? Do you know if they play today, Friday or Sat? Sorry to be a pain, but I am only here until Sunday.
