The cheers will get a little louder. The lines for concessions will get a little longer. And the feel of moving back to life as a sports fans will get a little more normal with more fans being allowed to attend to live sporting events.

The Mariners announced Tuesday that they have received permission from the state of Washington and King County to increase the seating capacity for baseball game at T-Mobile Park, starting with the upcoming homestand that runs June 14-23.

Per the news release, the updated operations plan for expanded seating “allows 26,265 tickets to be sold as vaccine only with no social distancing. The remaining capacity will be sold in socially distanced pods of 1-6 seats for a total of 4,680 seats. Total ballpark capacity under the approved plan is 30,945 (out of 47,000). Private Suites, Diamond Club and All-Star Club are available at full capacity for fully vaccinated guests.”

The Mariners have been operating under the previous state guidelines. They had approximately 9,000 socially-distanced seats available and then added roughly 5,000 seats for fully vaccinated fans.

The current plan is to open to full, non-socially distanced capacity when all COVID-19 restrictions in the state of Washington are lifted on June 30. That will go into effect for the homestand that starts on July 2.

As always, season ticket holders have priority to select locations for the upcoming homestand. Tickets will be available for single-game buyers starting on June 8 at


The Mariners will maintain the same mask policy where fully vaccinated fans are no longer required to wear masks at games. Masks are still required for those fans who are not fully vaccinated. Masks must cover both the nose and mouth at all times except when actively eating or drinking in their assigned seats.

The Mariners will also reopen some previously closed attractions and amenities on June 14, including the Baseball Museum of the Pacific Northwest and Mariners Hall of Fame, Moose Den, Kid’s Corner and Seattle Children’s play areas. The T-Mobile ‘Pen and Trident Deck will remain accessible only to vaccinated fans until further notice.

The Mariners will still offer free vaccinations during games administered by the Seattle Fire Department.
