What to know

T-Mobile Park is a 19.59-acre outdoor ballpark located in Seattle's SoDo neighborhood, near the western terminus of Interstate 90. Serving as the home stadium for the Seattle Mariners, the venue has a seating capacity of approximately 47,368 to 47,929. The facility first opened its doors for an inaugural game on July 15, 1999, where the Mariners suffered a 3–2 loss to the San Diego Padres. The architecture is defined by a one-of-a-kind retractable roof that covers nearly 9 acres. This massive structure weighs 22 million pounds and contains enough steel to construct a 55-story skyscraper. Designed to cover rather than fully enclose the park, the roof preserves an open-air environment while protecting the real grass playing surface from the elements. While primarily known for Major League Baseball, the venue also hosts Washington high school state championships and one Washington Huskies game per season. The park underwent a significant branding shift on January 1, 2019, when it became T-Mobile Park following a 25-year naming rights agreement. This partnership includes a $600 million investment in maintenance and upgrades over the next quarter-century. Visitors to the park can enjoy breathtaking sunsets over Puget Sound and views of the city skyline. The venue is highly accessible, situated less than 1 mile from the King County Water Taxi terminal at Pier 50 and the Washington State ferry terminal at Pier 52.
