T-Mobile Park is a retractable roof stadium in Seattle, Washington, United States. It is the ballpark of Major League Baseball's Seattle Mariners and has a seating capacity of 47,929. It is in Seattle's SoDo neighborhood, near the western terminus of Interstate 90. It is owned and operated by the Washington State Major League Baseball Stadium Public Facilities District. The first game at the stadium was played on July 15, 1999.
During the 1990s, the suitability of the Mariners' original stadium—the Kingdome—as an MLB facility came under question, 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) revived public desire to keep the team in Seattle. As a result, the Washington State Legislature approved an alternate means of funding for the stadium with public money. The site, just south of the Kingdome, was selected in September 1996 and construction began in March 1997. The bonds issued to finance Safeco Field were retired on October 1, 2011, five years earlier than anticipated.
T-Mobile Park is also used for amateur baseball events, including the Washington Interscholastic Activities Association high school state championships and one Washington Huskies game per season. Major non-baseball events that have been held at T-Mobile Park include the 2001 Seattle Bowl and WrestleMania XIX in 2003, which attracted the stadium's record attendance of 54,097.
The stadium was originally named Safeco Field under a 20-year naming-rights deal with Seattle-based Safeco Insurance. T-Mobile acquired the naming rights on December 19, 2018, and the name change took effect on January 1, 2019.
Location and transportation
T-Mobile Park is in the SoDo district of downtown Seattle, bounded by Dave Niehaus Way (a block of 1st Avenue S.) to the west, Edgar Martínez Drive (formerly S. Atlantic Street) to the south, Royal Brougham Way to the north, and BNSF railroad tracks to the east.
Parking is available at the stadium's parking garage across Edgar Martínez Drive, the Lumen Field garage to the North, and other privately operated lots in the area. Sounder commuter rail serves nearby King Street Station. T-Mobile Park is also served by the 1 Line of Sound Transit's Link light rail system and local King County Metro and Sound Transit Express bus routes at the nearby Stadium station.
A dedicated ride-hailing lot opened in June 2023 along 3rd Avenue; it cost $2.8 million to construct and was opened ahead of the 2023 MLB All-Star Game.
History
On March 30, 1994, county executive Gary Locke appointed a task force to assess the need for a new baseball stadium to replace the rapidly deteriorating Kingdome. Many feared that the Mariners would leave Seattle if a new stadium was not built. In January 1995, the 28-member task force recommended to the King County Council that the public should be involved in financing the stadium. The task force concluded that a sales tax increase of 0.1% (to 8.3%) would be sufficient to fund the stadium. King County held a special election on September 19, asking the public for this sales tax increase; the measure led early, but was narrowly defeated by one-fifth of one percent.
On October 14, a special session of the state legislature authorized a different funding package for a new stadium that included a food and beverage tax in King County restaurants and bars, car rental surcharge in King County, a ballpark admissions tax, a credit against the state sales tax, and sale of a special stadium license plate. Nine days later, the King County Council approved the funding package, and established the Washington State Major League Baseball Stadium Public Facilities District to own the ballpark and oversee design and construction. Taxpayer suits opposing the legislative actions and the taxes failed in the courts.
On September 9, 1996, the site was selected for the new stadium, just south of the Kingdome. In late fall, several members of the King County Council wrote a letter to the Seattle Mariners, requesting a postponement of the projected $384.5-million stadium project.
