There were 44,607 people in attendance that night. Seattle Mariners Hall of Fame Seattle Mariners former chairman and CEO John Ellis announced on June 14, 1997, the creation of a Mariners Hall of Fame. It is operated by the Seattle Mariners organization. It honors the players, staff and other individuals that greatly contributed to the history and success of the Mariners franchise. It is located at the Baseball Museum of the Pacific Northwest in T-Mobile Park. The most recent Mariners Hall of Fame member, Ichiro Suzuki was inducted August 27 2022. Retired numbers The Mariners plan to retire uniform numbers only very selectively and subject to substantially higher expectations than those applied to the Mariners' Hall of Fame. To be eligible to have one's number retired, in addition to the criteria outlined for the Mariners' Hall of Fame, the former Mariners should have either: a) been elected to the National Baseball Hall of Fame and been in a Mariner's uniform for at least five years, or b) come close to such election and have spent substantially his entire career with the Mariners. Eligibility shall not commence until after the former player has been voted on once for the National Baseball Hall of Fame, which for all practical purposes means six years after retirement. Ken Griffey Jr.'s No. 24 was retired at the beginning of the 2016 season, with the retirement ceremony taking place on August 6, 2016. Griffey had been elected to the Hall of Fame in January of that year. Edgar Martínez's No. 11 was retired during the 2017 season, with the retirement ceremony taking place on August 12, 2017. Martínez played his entire major-league career in Seattle and first appeared on the Hall of Fame ballot in . His No. 11 was retired in 2017, predating his 2019 election to the Hall of Fame and seemingly establishing the 58.6% of the vote he received that year as sufficiently "close" to election to satisfy the club's bylaws. Jersey No. 11 was not issued to anyone else between Martínez's retirement as a player in 2004 until his return to the Mariners as hitting coach in 2015. Currently, only one other player has definitively met the requirements
