T-Mobile Park (formerly Safeco Field)

T-Mobile Park opened in 1999 as Safeco Field and serves as the home stadium of Major League Baseball's Seattle Mariners. The ballpark features a retractable roof and a natural grass playing surface, making it one of the relatively few MLB stadiums with a retractable roof. It hosts baseball, concerts, and other large events and anchors Seattle's SoDo sports and entertainment district.
