Seattle Mariners

Every MLB player the encyclopedia attributes to the Seattle Mariners from profile season records, grouped by position, first season to last. Coverage follows the encyclopedia’s per-era source depth.

Every position room Seattle Mariners has passed down, steadiest first. The C room is their most stable — 3 holders across 33 years, a new one every 8.3 on average.

+2 more rooms with a shorter average hold.

Room tenures, not starting jobs — the corpus has no per-season depth chart, so holders can overlap (a successor often arrives before his predecessor leaves) and the measure is how often the room changed hands. A holder is a player who produced real value for this club during his years here, which is what separates holding the room from being on the roster. Detected from per-season VAL (1977–2026 here; league coverage is complete from 1999) — rooms the corpus cannot value are not shown.
