Griggs arrived in Seattle in the summer of 2021 after four seasons as the chief business officer for Atlanta United in MLS. She oversaw all aspects of the Mariners organization outside of baseball operations. At the time of her hiring, the team said Griggs was the only woman to hold a president title with a club in the majors.
Stanton will assume Griggs' responsibilities on a interim basis until a new person is hired for the position. Griggs' tenure in Seattle included hosting major events like the 2023 All-Star Game and the 2024 NHL Winter Classic, as well as the Mariners making the postseason in 2022, ending a 21-year playoff drought.
Griggs was hired as the replacement for Kevin Mather, who resigned in February 2021 after video surfaced of him making derogatory remarks about some players and club operations.
