What happened: The Seattle Seahawks posted that they "brought The Dark Side to the diamond," marking a cross-sport appearance at the Seattle Mariners' ballpark. The video-attached social post frames the visit as a themed promotional crossover between the city's NFL and MLB clubs.

Why it matters: Offseason crossover appearances like this keep the Seahawks brand visible during the NFL's quiet stretch and lean on Seattle's shared fan base across the two franchises. With football still months away, the club is leaning on community and partner content to maintain engagement.

What to watch: Watch for further Seahawks offseason content as the team builds toward its 2026 schedule, recently teased in the club's own social timeline.
