Buildings the Mariners have called home in the attendance data Ticket Timeline uses—useful when an old ticket names a former ballpark or an earlier naming-rights label.
Ticket Timeline's game data covers Mariners home ballparks from 1969, with gaps where source rows do not connect continuously.
If your ticket says Safeco Field, that's the same building under an earlier name.
Seattle Mariners play home games at T-Mobile Park in Seattle, WA, USA. Dates for those nights are anchored in Pacific time. The building list above is what Ticket Timeline uses when an older ticket names a former ballpark or an earlier name of the same building.
Use that timeline when dating a night: Sick's Stadium (1969–1969) is a former home—a different building from T-Mobile Park, not a rename; Kingdome (1977–1999) is a former home—a different building from T-Mobile Park, not a rename; and tickets that still say Safeco Field refer to T-Mobile Park—the same building under an earlier name. Rebuilding Mariners attendance is usually a scavenger hunt: paper tickets and PDF confirmations, camera-roll scoreboard dates, calendar invites, season-ticket statements, and memory anchors (companions, rivals, life events, ballpark names on stubs). Work season by season; a partial list of attended games is enough to start matching opponents and ballparks. When confirmations live in Gmail, import games you've attended walks through a read-only preview before anything is committed. For a shoebox of stubs, see what to do with old ticket stubs.
Start from the record you already have. Import a spreadsheet of Mariners games, recover confirmations when you can, or add older nights at T-Mobile Park manually. Ticket Timeline is built to reconstruct attendance history, not replace a ticketing app.

Mariners home games today are at T-Mobile Park. Former homes and earlier printed names live in the venue timeline above—use those when an old ticket does not say T-Mobile Park.
Add Mariners games from memory, import a spreadsheet, or scan ticket stubs. Ticket Timeline links each attended game to MLB context—teams, ballparks, players, and notable moments—so nights at T-Mobile Park and elsewhere become a browsable Seattle Mariners archive. Primary focus on this page: importing past attendance.
If your Mariners attendance still lives in Sheets, CSV rows, stubs, or memory of T-Mobile Park, Ticket Timeline is built for migration. Import what you can, fill gaps manually, and keep attended games exportable across seasons.
If your stub names Sick's Stadium, that is only the Mariners' 1969 debut season—a sharp dating clue. The Kingdome was a former Seattle home, not an earlier name for T-Mobile Park. Safeco Field on a spreadsheet row matches the same building under its earlier printed name when you are importing older Mariners attendance.
