Randy Johnson’s Legacy with Mariners is Indelible

The Mariners are set to retire Randy Johnson’s No. 51 this weekend during their series against the Kansas City Royals. The festivities kick off with “Randy Johnson ‘80s Jersey Night” on Friday. The ceremony will be held before Saturday’s game.

It’s not very often that a franchise has two of its icons wear the same number. Ichiro Suzuki also wore No. 51 for Seattle, which was retired on August 9, 2025, after he was inducted into the Baseball Hall of Fame.

“The Big Unit,” Randy Johnson, was inducted into the Baseball Hall of Fame in 2015. Now, 11 years later, he gets the ultimate honor from the Seattle Mariners of having his number retired. He was also inducted into the Mariners’ franchise Hall of Fame in 2012.
