2010 Disable List Spreadsheet and Team Information

Overview

I have finally gone through the MLB transaction data and have compiled a spreadsheet of the all of the trips to and from the disabled list for the 2010 season. Feel free to download the data and use it as you see fit. If you use the data in your own article/research there is no need to reference my work since the data can be obtained freely. I am just wanting to make it available for people to use. If you do plan on using it, here is an explanation and limitation of the data.

Explanations of the columns:

Team – The team that placed the player on DL.
Trans – The date that the official transaction occurred – This can be different than the official start date as some injuries occurred before the player was on the DL
POS – Position of the player
First – First name of the player
Last – Last name of the player
Started – When a player’s official DL time starts
StartedInSeason – Some players were placed on the DL in January. This date marks the date when the player actually begins to miss regular season games.
End – When the player’s official DL time ends. Many of these records are unknown right now because teams haven’t taken all their players off the DL yet.
EndedInSeason – Many players are still on the DL, even though the season has ended. This marks the date when the player no longer misses any regular season games.
TotalInSeasonDays – Total days missed during the 2010 season
Transferred to 60 day DL – Date the player was transferred to the 60 day DL (if applicable)
Disabled list – If the player was initially placed on the 15 or 60 DL.
Side – Side of the body (if given)
Location – Part of the body that the injury occurred. It will be filled out for each player.
Body Type – Body type (i.e. bone, ligament) injured. This was only filled out if listed in the transactions
Injury – Type of injury that occurred. If there was none listed, the vague term “injury” was used. I plan on looking these up on a later date. It will be filled out for each player.
Extent – Extent of injury, if given.
Surgery – Used if surgery was known. There are definitely more surgeries that happened, but these were the only ones listed in the transactions.
Surgery date – Date of the surgery.

Limitations

The data is probably only 90%-95% correct at this point. Going through the data, there was quite a bit of missing information, especially when it came to players going on the 60 DL or when a player was taken off the DL and then sent to the minors. If anyone sees an error, I will gladly fix the data and mark it in the versions at the bottom of the spreadsheet. You can email errors to me at wydiyd ~ hotmail ~ com

Well enough of background information, how about some graphs.

Team Data

Here is how each team fared in the total number of trips to the DL:

Here are the total days lost to the DL for each team:

No data really stick out to me, except for the huge discrepancies from the teams on extremes of days lost. The Oakland Athletics lost five time as many games to the DL than the Chicago White Sox . In the next day or so, I will be breaking down the data according to position.
