Every row is captured from MLB’s official StatsAPI transactions feed with MLB’s published description unedited. A trade appears on both clubs’ pages for the season; signings include both major-league and minor-league contracts signed with the club; injury-list moves and minor-league affiliate-only transactions are outside this archive’s scope.
Oakland rows through 2024 are Oakland Athletics moves: the franchise relocated to West Sacramento for the 2025 season and the feed now lists every row under the current name.
