The Seattle Mariners, with the help of superstar centerfielder Julio Rodriguez, announced the second collaboration between the team and apparel company, One Piece. Themed jerseys will be given away to attendees with a special event ticket, and these will resell for a lot more than the cost to attend. Free beer, free hot dogs, and free seats are being promised for attendees to the promotion on the night of the team’s home game against the on March 31.
With its anime style design, the shirt is a perfect polyester fit for J-Rod, who is a big fan of the genre and its surrounding culture. So, naturally, he is the spokesperson and the face of the event.

These shirts are considered collector’s items and somewhat like currency by those who deal in sports memorabilia and apparel. A $100 ticket could land you a $250+ jersey on the secondary market. So, much like those who deal in MLB autographs, or specially-themed ball park promotions like a bobble head night, there will be people who are there simply looking for a return on their investment.
Unfortunately, special event tickets for Seattle’s One Piece Night are currently sold out. However, more tickets will likely become available as the date draws closer. Fans are encouraged to check the Mariners team website for updates.
