One Piece Seattle Mariners Baseball Game Event Set for April

Toei announced yet another One Piece night for a US team, and this time it’ll involve the Seattle Mariners and Houston Astros baseball game on April 8, 2025. The event will be designed to highlight the manga and anime series and the card game. 

Tickets are now on sale for the T-Mobile Park event in Seattle, Washington via the official site. If they don’t sell out, then they will be available until April 7, 2025. These start at $21 for a View Level seat, though $41 Main Level and $51 Club Level ones are also available. Each one of these special purchases for the event also entitles people to a shirt with the One Piece logo and Luffy on it. 

Here’s the key art for the event. It features Luffy below the logos for One Piece, the Astros, and the Mariners. 

And this is the matching shirt that will be given away to ticket holders.

While the site notes the event starts at 6:40pm PT on April 8, 2025, there will be events before the game. These will be held at Victory Hall. Exact One Piece elements weren’t mentioned., aside from chances to see the One Piece Card Game. Previous events included photo ops and other anime imagery.

This is the third One Piece night at a sporting event to show up in the US in 2025. The first involved a Laker’s game in February 2025. The other will be a Red Sox game against the Twins in May 2025. 

The Seattle Mariners One Piece night will fall on on April 8, 2025, and people can attend the baseball game against the Houston Astros at T-Mobile Park in Seattle, Washington. You can find the anime on Crunchyroll and Netflix, and Viz Media handles the manga outside of Japan. The live-action adaptation is only on Netflix.
