Root Sports Northwest aired its final broadcast on September 28, 2025, with the Seattle Mariners' home game against the Los Angeles Dodgers, concluding more than three decades of regional sports television in the Pacific Northwest. This final sign-off marked the Mariners' official exit from the regional sports network business, transferring game telecasts and streaming distribution to Major League Baseball starting in 2026. Earlier on September 26, 2025, the Seattle Mariners, who became sole owners of Root Sports after purchasing the remaining stake from Warner Bros., revealed plans to shutter the network in 2026, with Major League Baseball scheduled to take over the club’s broadcasts.
