The Seattle Mariners officially retired Randy Johnson's jersey number 51 during a pre-game ceremony on Saturday [1, 2].
The event honors one of the most dominant left-handers in baseball history. By retiring the number, the franchise cements the legacy of the Hall of Fame pitcher within the organization's permanent history.
The ceremony took place at T-Mobile Park in Seattle, Washington [1, 2]. Johnson, widely known by his nickname "The Big Unit," is now the second player to have the number 51 retired by the Mariners [2].
While the team held the ceremony this past Saturday [1], some reports had previously indicated the retirement would occur generally during the 2026 season [4]. The event serves as a formal recognition of Johnson's contributions to the team's success during his tenure in Seattle.
Johnson's career is marked by his stature and strikeout capability, which earned him a place in the National Baseball Hall of Fame. The retirement of his jersey number 51 [1] ensures that no future Mariners player will wear the digit, preserving it exclusively for the pitcher's legacy.
The Mariners organization used the gathering to reflect on the impact Johnson had on the franchise and the city. The ceremony included tributes to his performance on the mound and his influence on the game of baseball.
