Mariners to Retire Randy Johnson’s No. 51 in 2026

The Seattle Mariners will retire Hall of Fame pitcher Randy Johnson's No. 51 jersey during the 2026 MLB season, following Johnson's decision to delay the honor so Ichiro Suzuki, who also wore No. 51, could have his number retired first in August 2025. Johnson, a five-time All-Star with the Mariners, won the 1995 Cy Young Award, threw the franchise's first no-hitter, and played a pivotal role in leading Seattle to its first postseason. Both Johnson and Ichiro, Hall of Famers and franchise icons, wore No. 51, making the Mariners' decision to retire the number for both players a tribute to their lasting impact. Johnson ranks second in strikeouts and third in wins in team history, while Ichiro was a 10-time All-Star and AL MVP. Johnson's number retirement will be the sixth in Mariners history, joining Ken Griffey Jr., Edgar Martinez, Ichiro Suzuki, and Jackie Robinson. The exact date of Johnson's ceremony will be announced after the 2026 schedule is finalized.
