Randy Johnson’s Number to Be Retired by Seattle Mariners on May 2, 2026

Randy Johnson’s number will be retired by the Seattle Mariners on May 2, 2026. Attend the pregame ceremony honoring the Hall of Famer during the weekend.

Randy Johnson will officially join Ken Griffey Jr., Edgar Martinez and Ichiro when the Seattle Mariners retire his number in a pregame ceremony on May 2, 2026. The announcement caps a weekend celebration that will honor one of baseball’s most dominant left-handers and recognize his lasting impact on the Mariners franchise.

Known as “The Big Unit,” Randy Johnson forged his legacy with the Mariners in the 1990s before winning a World Series and multiple Cy Young Awards with the Arizona Diamondbacks. A five-time Cy Young Award winner and a Hall of Famer, Johnson’s overpowering fastball and devastating slider made him one of the game’s most feared pitchers. His career accomplishments — including over 4,800 strikeouts and more than 300 wins — place him among baseball’s true greats.

For the Mariners, retiring Johnson’s number is a natural addition to a distinguished list that includes Griffey, Martinez and Ichiro. Each of those players defined eras for Seattle baseball; Johnson’s inclusion recognizes his role in elevating the club’s profile and energizing the fanbase during a period of dramatic growth for the franchise. The ceremony will be a moment for fans to reflect on historic performances and celebrate a hometown hero who helped shape Seattle’s baseball identity.

Details about the May 2 pregame ceremony will be released by the Mariners closer to the date, but fans can expect tributes from former teammates, special video retrospectives, and a display of Johnson’s retired jersey at T-Mobile Park. The weekend celebration will likely include alumni appearances, fan events, and opportunities to honor Johnson’s contributions both on and off the field.

Tickets for the celebration are expected to be in high demand. Fans should monitor the Seattle Mariners’ official website and social channels for ticket information, event schedules and broadcast details. Those who can’t attend in person can look for televised or streaming coverage of the pregame ceremony.

Randy Johnson’s number retirement is more than a ceremony — it’s a recognition of a career that left an indelible mark on Seattle and Major League Baseball. Mark your calendars for May 2, 2026, to join in celebrating one of the sport’s most dominant pitchers.
