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).
btw...Thanks AZ Phil. I'm really enjoying your take on this trade.
I'm a bit disappointed on the Warren experience. Essentially they gave Castro away for crickets (OK, well they signed Zobrist with the Castro salary dump). Otherwise one might look at it as Chapman for Castro and our #1 minors prospect (Torres) + McKinney/Crawford. Seems pricey for a 2 month rental. We will see if this price tag is that steep in a relative way based on the remaining deadline deals for relievers.
Yep. One of the great things about this team (in addition to being really good at baseball) was the "likable" factor. Feels a bit different now. Who knows...maybe Chapman will be the king of the dance parties.
Here are some possible corresponding minor league moves we might see in the aftermath of the Chapman trade:
SOUTH BEND to MYRTLE BEACH: OF Donnie Dewees and INF Bryant Flete
EUGENE to SOUTH BEND: OF Robert Garcia and INF Vimael Machin
There is really no reason to replace Billy McKinney at Tennessee because both Chris Coghlan and Jorge Soler are doing their rehab at Tennessee.
And there are plenty of pitchers at Iowa. No need to replace Warren at AAA. .
I am 70 years old. The Cubs last played in the World Series in 1945. I was born in 1946. I hate to lose a prospect like Torres, but when the opportunity is there to get that World Series ring, you go for it. This was the idea in stock piling all this young talent. I would like to see Reddick added now and the Cubbies should be done.
I would expect Richard to accept an optional assignment because based on how he's played this season, there is a decent chance that he won't find work elsewhere. Rather stay and potentially get a ring. Same goes for Coghlan since he's struggled mightily this year.
Edwards should not go down. He's pitched very well and Maddon is very impressed with him. I would expect Grimm to go down for Cahill so he can get back on track (he's pitched better in July, but he's not getting enough appearances).
chitownmvp01: Indeed Clayton Richard would seem to be odd man out once Chapman reports, but Richard might accept a minor league assignment if he is promised a return to Chicago on 9/1 when MLB Active List rosters expand (Richard has minor league ioptions left).
The only player in the deal that would cause me a second thought is Gleyber Torres.
McKinney and Crawford are decent prospects but both are redundant/replaceable in the system and Warren was really only a middle-reliever or #6 starter, so to me it's really just Torres for Chapman.
There is no Comp pick for players traded mid-season. 2+ months of Chapman is it.
to get one of the best you have to give up one/some of your best...but it's a bit painful to watch the system's best prospect walk for any 2-3 month rental, especially one that's not an everyday player.
I assume Chapman will replace Richard on the roster, but who goes down when Cahill gets activated? Maybe Grimm?
And when Soler and Coghlan get healthy, how do they fit them on the roster when they're ready to be activated?
We are giving up a lot, but it's not like we're trading Addison Russell for 2+ months of Jason Hammel. When impact players become available, they are going to cost you. The other bids could also have been high.
Having Chapman as a rental is potentially less disruptive than having him come in with an extension in place.
Billy McKinney had season-ending knee surgery last August and came to Minor League Camp this year somewhat restricted. (He was used mostly as a DH in Cactus League Minor League Camp games), and I'm not sure he's 100% right now (he's repeating AA, and his XBH numbers are way down, like he's not getting good rotation in his lowev half). That might have been part of the reason why the trade wasn't completed right away.
Rashad Crawford was a basketball star in HS (he was known as "Baby Jordan", and baseball was only his second sport) and he has plus-speed and athleticism, so when the Cubs drafted him (Keith Lockhart was the scout) he was seen as a long-term project.
I was at Fitch Park the day that Rashad Crawford became a LH hitter, He waa never a switch-hitter, He went directly from being a RH hitter to a LH hitter, which I had never seen before.
I'm with Rob G and Johann here. It's not about Chapman as a pitcher. I just don't want to have to block out a real problem (the domestic violence) in order to try to enjoy the frivolous ball and stick game.
ROB G & BOB R: You're right. The QO can only be extended if the player spends the entire previous season with one club, so only the Yankees could have offered one to Chapman (if he wasn't traded). If an Article XX-B FA is traded during the season, the new club can't offer a QO. .
