About these records
Every dated event on this page is read directly from the source tables: debuts, final games, birth dates and death dates from the SABR / Sean Lahman baseball database (2025 edition, People table), used under Creative Commons Attribution-ShareAlike 3.0, and transactions from the official MLB StatsAPI transactions archive captured through 2026-10-22. Nothing is inferred: a record appears here only when the source carries a complete month and day for May 12.
Honesty notes: the staged People table records complete dates or none, and no partial dates had to be excluded. Missing dates are not unknowns everywhere: an empty death date means the player is living (10,918 rows), an empty final-game date means no end date is recorded (1,932 rows), and 398 rows have no birth date. Early records reach back to the 1870s; 19th-century dates reflect the best retrospective research in the source and are shown exactly as recorded. Award winners and postseason series are staged by season with no calendar day in the source, so they are linked from each season above instead of being dated here. The transaction window covers 2011 to 2026 only. Player names link to career pages for every player who has one.
