Today I have a very special jersey for sale. This jersey was worn by the Mariners on August 6th at Safeco Field, the night the Mariners retired their first number… This jersey was worn by the starting pitcher, Taijuan Walker. The jersey shows amazing game used stains and carries some odor as well. I have also added a picture of Taijuan wearing the jersey (above in the pictures). The authentication is bellow.
