This jersey was created to commemorate SpongeBob SquarePants Night at T-Mobile Park on Tuesday, August 4, 2026, when the Seattle Mariners host the Detroit Tigers—a special event that brings the entire world of Bikini Bottom to Seattle’s home ballpark. The Mariners SpongeBob Jersey 2026 is currently available as part of the special ticket package for fans attending the game.
