Players take responsibility as a role model seriously…

By Tangotiger, 09:46 PM

What the players felt strongly about were two aspects of this. One was, they felt strongly that the union does have a responsibility to try to ensure the health of its members. And there are provisions in here where, jointly, we will work on that, in terms of cessation and in terms of treatment.

Players also embraced the idea that kids look up to them. And players look forward to the idea of being involved in a public education program, working with the Partnership at Drugfree.org, an organization we’ve worked with for a couple of years now. We will now expand what we were doing with them to include smokeless tobacco.

So the players felt strongly about the health issue and about the education issue.

... to a point

They also did feel strongly that it wasn’t the job of the union or management to tell players that they could not use this on the field. So we made changes in restricting the ability of players to use it in interviews and things of that sort. But notwithstanding the view of many that we should ban it on the field, that was a line that the players weren’t prepared to cross.

Reminds me of when the two Corey’s in the 1980s said they were involved in the “Just Say No” campaign with Nancy Reagan, and after they did their public service announcement, they’d “Always Say Yes”.

Injury days unused because of retroactive placement

By Tangotiger, 12:08 PM

In MLB, you can make a DL move retroactive.  This is sort of like insurance: rather than put him on the DL (for 15 days) for what you think is an injury, you wait.  This way, if it’s not really a 15-day injury, you still have the player available.  But, if it really is, you make it retroactive (but you play shorthanded until then).

The A’s and Rangers like to do this apparently, and the Yankees don’t:

Handling young pitchers

By Tangotiger, 10:35 AM

Lincecum and Hughes:

But how much to throw, and how exactly to throw, has become one of the game’s great debates. Lincecum, for example, credits his late-season surge a year ago — he went 0-5 with a 7.82 ERA in August, then went 5-1 with a 1.94 in September — to going back to the extreme long-toss program he utilized as a high school and college pitcher. After a deliberate warm-up routine, Lincecum routinely airs it out on his off days, playing catch at farther than 300 feet for five to 10 minutes to build his arm strength. There were even days when Lincecum was spotted long-tossing with a friend in a park in San Francisco. His jump in velocity from August to September and October was almost four mph.

Not everyone has had the same success bouncing back as Lincecum. According to the velocity-tracking website FanGraphs.com, Pelfrey recovered most of his velocity (getting back to 92 to 93 mph) during the second half of the 2009 season, but has dipped again for parts of the last two seasons. “I am a believer in long toss,” Pelfrey says, “Especially in spring training, it’s a great physical and mental exercise. In the beginning of the spring, I struggle to throw the ball 120 feet, and by the end of the spring I’m throwing it 250-300 feet easily. That’s great evidence that your arm is strong.”

PITCHf/x injuries

By Tangotiger, 11:08 AM

Kyle looks to see what we can find.  MAYBE elbow injuries are somewhat linked to sliders and release points.

The more likely culprit is either a person’s body (if we can somehow quantify the body), or just plain (bad) luck.

Effects of concussions

By Tangotiger, 04:58 PM

Whoah, great stuff from Jeff, with a nearly 40 point drop in wOBA!  That is enormous, turning an average player into a replacement-level player.

As you know, I’m skeptical of any claim from anyone that can find a split effect in any category that is more than the handedness effect (20 points in wOBA).  And one would think that returning from a concussion means that you’ve had enough rest before coming back.  Clearly, that’s not the case.  I would like to see a longer-term trend in terms of how long before the player finally has recovered.  It’s no surprise that your performance is much worse following a concussion.  It does seem to me to be a surprise that your performance is this much worse after given the selective rest you needed (or thought you needed enough of).

This is huge no?  That you might simply say “you need at least 30 days off” or something before being allowed back on the field.

Not losing money to injuries

By Tangotiger, 04:35 PM

Will:

Many will ask how I know this to be true, and I’ll direct you to look at the massive gap between the best teams and the worst teams when it comes to keeping players healthy. This isn’t a flukish statistic, but one based on a decade of numbers. Looking back through 2002, the gap between the best and the worst teams is almost $100 million dollars.

It sounds like alot, and it sounds like there’s not much luck there, but, we’d need to test that.

Forecasting likelihood of starting pitchers being injured

By Tangotiger, 07:51 PM

Fantastic stuff from Jeff: part1, part2.

First off, the mean forecast for any starter is 40%.  So, Jeff’s got his forecasts, at the extreme, at +/- 15%.  I have to believe the uncertainty of his estimate is going to be mighty high, some +/-20%.

Secondly, the median stay is some 50 days or so.

Conclusion: pitchers are expected to miss ALOT of time.

Expanded playoffs

By Tangotiger, 11:42 AM

"Yeah, expand it because [standard reasons].”
“No, leave it as it is because [standard reasons].”

Please, do not post if you are going to give [standard reasons].

What I am surprised about is this:

Giants reliever Jeremy Affeldt is concerned that adding wild-card teams or increasing the length of the division series would make a long season even longer.

“If they’re going to do that, they need to shorten the season then. That’s a lot of games and that’s a long time. Even in the playoffs now we’re going potentially to Nov. 5,” he said. “Sometimes they think we’re just robots, but you’ve got to think of potential injuries. On pitchers, that’s a lot of throwing. Position players, some play every game all year. It just takes a toll on the body. If they’re going to do that, they’ve got to think a lot about the ramifications.”

Does Affeldt realize that if they cut the number of regular season games that he’s going to be paid less?  The number of games is a workplace safety issue.  If it was up to the owners, they’d have the players play for ten months.  If it was up to the fans, we’d have them play for eleven months.  (What, you’d rather hear Harold Reynolds talk from November through March?  I didn’t think so.) The players should play for as long as they think they can play, AND THEN, their salaries would be based on that (i.e., revenue collected).  Really, if players said that they should only have a 120 game season for health reasons, and that their salaries would be cut by 25%, then the owners would fight and eventually give in.

The reality is that players have always been willing to sell their body for money.  It’s not the owners and fans who think the players are indestructible, but the players themselves.

Using injuries for forecasting

By Tangotiger, 09:17 AM

Now here’s some new ground being broken:

As an example, let’s consider hitters who went to the disabled list with an injury to the lower arm (hand, wrist, or forearm). It’s widely accepted in baseball that wrist injuries have a lingering impact on a hitter’s ability to hit for power. This gives us 77 hitters to study, with 32,763 total plate appearances the following season.

Using the same method we used to look at Ichiro Suzuki yesterday, we can come up with an expected batting line for these hitters. As a group, weighted by playing time, they were expected to hit .266/.333/.427 the following year. Instead, they hit .270/.344/.439.  So we can see that these hitters as a group tended to exceed their baseline forecasts.

It will be interesting to see how much is real (causation) and how much is best-fitting (correlation).  But, definitely, this is one of those untapped areas.  I have to believe that this will impact pitchers far more than non-pitchers.  This will be pretty fun to watch develop.

And, this warms my open source heart:

So what we’ve done is taken a publicly accessible injury database, created by Josh Hermsmeyer of RotoBase, and worked on proofing it and improving it for incorporation into PECOTA. (Once we’ve finished updating the database, we will be releasing it at some point during the offseason, for other researchers to use.)

Frequency of pitching injuries, and recovery time

By Tangotiger, 10:18 AM

Using the Rotobase or Dawkins Injury Database leads to fun stuff, as you can see from a widely cited academic paper, or the non-doctorate saberist paper, or from Neyer‘s points regarding selection bias.

Do players who sign with their own teams age better than those who don’t?

By , 02:15 AM

About 3 weeks ago, Matt Swartz wrote an article on BP that concluded fairly emphatically that players (pitchers and hitters) who sign multi-year deals with their own teams aged and performed significantly better than those who did not.  To be honest, I did not re-read the article carefully and it is not real clear what the criteria were for the various groups of players.

Here is what he wrote at the end of the article:

What appears to be happening is that teams seem to have some sense of the aging curve of individual players, especially if they are already in their organization. There are probably a variety of reasons that this subset of players aged well, but the team knowledge about the player’s medical and scouting information appears to contribute to the decision to give a player two-year deals. This is important to keep in mind when we hear of a player signing a new contract and look to a projection system to figure out how smart the deal was. Chances are that there is additional information—especially about aging—which teams have that we may not.

Today, he wrote a long article telling us why the Ryan Howard contract might not be as bad as some analysts are making it out to be.  One of the reasons he cites that it may not be so bad is that because Howard is signing with his own team, he may age better than we think (using comparable players, the traditional aging curves, etc.).

LASIK schmASIK

By Tangotiger, 06:59 AM

Great stuff:

Year before LASIK: 97 wRC+
Year after LASIK: 109 wRC+

Now that looks pretty significant. However, you figure that players would be more likely to get something fixed after a bad season than a good season, right? Let’s narrow this group to the 24 players for whom we have three years of big league data.

Two years before LASIK: 112 wRC+
One year before LASIK: 96 wRC+
Year after LASIK: 109 wRC+

Well there you go. Definitely a response to frustrating seasons.

Actuarial tables for injuries?

By Tangotiger, 11:11 AM

Rick Wilton, who is one of the two injury experts I follow (Will Carroll being the other… if there’s someone else, please post below), says with Ron Shandler:

Why haven’t fantasy players seen groundbreaking analysis in the field of injuries? Why can’t we produce reports that state that Player A has suffered a strained oblique injury and he has a 71% chance of spending 28 days on the DL, 12 % of landing on the DL for 29-34 days and so. I argued that while we had seen advances in injury analysis and reporting since I got into the field in the early 1990s, putting a number on it would be tough.

I think the answer is even easier: until last week, the public did not have a ready-to-download database.  You can’t analyze without data.  That’s why the Lahman database is a godsend, and that’s why Retrosheet is a godsend.  Without easy-access to data, there is an enormous amount of ineffecient effort in collecting the data.  Or, alot of money to give to someone to licence you the data.  Data.  That’s all we need.

So, you will see in the next 12 months what the public can do with injury data.  And something like Rick is asking will be answered.  Ideally, the subject matter experts would be able to give us a “scouting report” so that we have something to regress to that is more meaningful than whatever we can infer from the data.  Those guys can reduce our uncertainty rate in our estimates a great deal.  I know there are tons of lawyers out there that are involved on the periphery of sabermetrics.  I’d like to see the doctors contribute as well.

Salaries lost by team, 2002-2009

By Tangotiger, 09:56 PM

Fantastic stuff.

Dear Rob Neyer:

You have pull with the media.  You know the media loves one-line sound bites.  You love to highlight the great work from the young guys.  Well, Jeff Zimmerman used the data of Josh Hermsmeyer to tell us that of the $18.6 billion in salaries paid out from 2002-09, that $2.9 billion went to guys on the disabled list, which is 15.5% of the payroll.  Blare that out in a headline, please.

Thanks, Tom

***

Jeff: can you split that up into number of days that exceeded 30 days on the DL for a stint?  The reason is because insurance only pays on day #31 and later.  The rest is considered short-term disability and is not covered, as best as I can tell.

***

Remember what I said about how teams insure contracts?  Let’s presume that of the 15.5% lost to DL, only a quarter of that was picked up by insurance (because only days 31+ are covered).  That’s about 4%.  If I read the above article correctly, it seems that premiums cost about 5% of team payroll.  Insurance companies profit from the difference.

So, prima facie, it seems that everything adds up pretty nice.  In any case, it’s nice to finally know.  Thanks Jeff and Josh.
