The Seattle Mariners will retire No. 51 for both Randy Johnson and Ichiro Suzuki. The Mariners traded Johnson to the Houston Astros in 1998, which vacated No. 51 for Ichiro to wear when he joined in 2001.
The Ichiro version of No. 51 will be retired by the franchise on Aug. 9, 2025, just after his Hall of Fame induction this summer. Ichiro will become the third Mariners player to have his number retired, joining Hall of Famers Ken Griffey Jr. (No. 24) and Edgar Martinez (No. 11). The Mariners, like all MLB teams, also have retired Jackie Robinson\'s No. 42.
Johnson\'s version will be retired by the Mariners at some point during the 2026 season.
