More information on the site can be found here and here. Basically you type in an active major leaguer's name and all his trips to the disabled list since the early 2000's show up with information on the type of injury, length of time on the DL, etc. It's pretty useful. Did you remember that Ben Sheets was on the DL for 46 days in 2001 due to right shoulder tendinitis? Hat tip to Bucs Dugout, the SB Nation Pirates blog.
