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).
Chapman shouldn't be reserved anymore on 40 man.
Interesting split on Heyward according to ESPN. As a CF, his slash line .292/.363/.375/.738. At RF: .212/.204/.300/.604. 21/72 as a CF, 58/273 as a RF.
He's also been better when batting 2nd, but he had a nice start in the 6 hole, but has slumped ever since. He was heating up before the All Star break, but is only hitting .108 in the 2nd half.
When we played the Reds with Chapman, I always thought of it as an eight-inning game. So now other teams have eight innings to try to get a lead against the Cubs. Should be a challenge, assuming three or four Cubs ever start hitting again.
I don't really try to get to know and like these players personally. I'm rooting for laundry, for the most part. Exceptions might be when a player makes trouble in the clubhouse or in the dugout. (Zambrano and Bradley come to mind. Also Papelbon.) But I don't think Chapman is one of those jerks.
Unfortunately, a pretty good summary. It looks like next year Heyward will be getting yet another batting stance adjustment.
The recent good news has been Baez. I'm afraid about the next league adjustment on him, though, which is probably right around the corner.
Bryant I don't worry about too much. Just not seeing the ball well right now. He'll turn it around. Russell's been good with men in scoring position all year and he's 22ish. He'll be fine but next year is likely to be his breakout year.
If Travis' back-to-back-to-back walks cost Hendricks the ERA title, that would really suck.
Edit: "A lifeless loss to a lousy Sox team."
This place is a real downer after a loss to the Sox.
I expect they will go 5-9 games above .500 the rest of the year. 96-98 wins will win the Division.
They should have one more 2-3 week hot streak in them.
However, several players are just "average" for the last month: Zobrist, Ross, Russell, Ceasar. Montero is terrible, plus he cannot throw anyone out. -WAR. Heyward is abysmal at the plate, but a plus in the OF. Still with RISP he has been terrible. KB has not been driving in runs as of late. But Apparently the team is still above average with RISP according to S Sahadev.
I came to that realization tonight. I kept expecting them to play better, but now I realize they aren't going to. They are a .500 team now.
- They have one reliable starting pitcher. Jake's magic is gone, and it doesn't look like it's coming back. Lester has been lousy recently. Lackey's ERA goes up every time he pitches.
- Heyward has been dead weight all year. I can't remember a single series where he was a significant offensive contributor. Not one. Great defense, but but if he were hitting .270 with 10 HR and played average defense, the Cubs would be better off.
new rule...no one's allowed to throw k.bryant a changeup
Team is .500 since early May and is playing like a .500 team. Lack of offense seems to be putting a lot of pressure on the pitchers...and they aren't handling it terribly well.
.500 the rest of the way still may win the division though.
...i hate espn.
nothing like settling into a cubs game to get a few minutes cutaway for an ortiz AB in the 6th inning of the det/bos game.
oh, at least they're doing split screen now...i guess.
I'm liking this rookie Nathan.
Richard DFA'd. Meh...
Throwbacks with fashionable cutouts would be a nice touch.
The next 2 games are nationally televised. I think we dominate tonight, hitting 3 HRs off Shields. Great night for KB to end HR drought facing HR prone pitcher in one of the most hitter friendly parks in the league.
