Retiring a number is the highest honor a franchise can bestow, a way of saying that what this person meant to the city, the team, and the fans can never be replicated. These are the Seattle Mariners legends whose numbers will never be worn again.
#11 - Edgar Martinez
Edgar Martinez spent his entire career in a Mariners uniform, and the numbers he put up over those years tell only part of the story: a .312 batting average, 309 home runs, and 1,261 RBI across 2,055 games in Seattle. He was the heart of some of the most exciting Mariners teams ever assembled, and his Hall of Fame election in 2019 felt like a long-overdue celebration for every fan who watched him work. The Mariners retired his number 11 because Edgar did not just play the game brilliantly, he defined what it meant to be a Mariner.

#24 - Ken Griffey Jr (retired August 6 2016) (Hall of Fame)
There has never been anyone quite like Ken Griffey Jr., and Seattle knew it from the moment he stepped onto the field as a teenager at the Kingdome. His effortless swing, his gravity-defying catches in center field, and his genuine love for the game made him the face of a franchise and a generation of baseball. The Mariners retired his number 24, and baseball itself followed by retiring it across the entire sport, a fitting tribute to a player who reminded everyone why they fell in love with the game in the first place.
