Safeco Field (originally rendered SAFECO Field and sometimes referred to as Safeco or The Safe) is a retractable roof baseball stadium located in Seattle, Washington. The stadium, owned and operated by the Washington-King County Stadium Authority, is the home stadium of the Seattle Mariners of Major League Baseball (MLB) and has a seating capacity of 47,878 for baseball. It is located in Seattle's SoDo neighborhood near the western terminus of Interstate 90.
During the 1990s, the suitability of the Mariners' previous stadiumthe Kingdomeas an MLB facility came under doubt, and the team's ownership group threatened to relocate the team. In September 1995, King County voters defeated a ballot measure to secure public funding for a new baseball stadium. Shortly thereafter, the Mariners' first appearance in the MLB postseason and their victory in the 1995 American League Division Series (ALDS) renewed a public desire to keep the team in town. As a result, the Washington State Legislature approved an alternate means of funding for the stadium with public money. Construction lasted until July 1999, and the stadium hosted its first game on July 15, 1999.
