About Day-to-Day

Keep track of Major League Baseball players' injuries with Day-to-Day! This site is an all in one place view of a team's injured list, with a timeline of events for each player so you get a clear picture of what's going on. The site is free to use and open source, and is not affiliated with Major League Baseball or any of its teams.

Where the data comes from

Roster moves (IL designations and rehab assignments) come from MLB's own transactions feed. The "narrative" stages come from reports, which are read by large language models and stored as a fixed progression. Every reported row links to the source it came from; check it out for more information or if something looks wrong. New updates are picked up hourly through the day.

Reading the table

  • Injury is the injury as listed by the team, which is often vague. The site does not guess at what it is but rather attempts to categorize it. Sometimes said categorization is wrong; be sure to check the source for specific information.
  • Timetable is estimated time still out, not return date. A plain figure is something a reporter published. A muted, ~ figure is this site's own estimate from what the injury usually costs — worth reading as a ballpark. Hover any of them for information on what the figure is based on.
  • Updated is the date of the newest thing said about the player, which is often older than you would expect.

Player pages

Search by name in the bar, or follow any name in the table. The page shows where the player stands now, as well as the whole sequence of events for their current injured list stint. Tags on an event say how firmly it was reported (expected, rumored), whether it was a setback, and which row the outlook at the top was read off.

What this is not

Day-to-Day is not official, and not a betting tool. It is a reading of public reporting. Reporting is sometimes wrong. Language models are sometimes wrong. The site is not a substitute for local beat reporters.
