Up for sale is my Mitch Haniger game used jersey. He wore this jersey during his 2017 rookie season, and it has been authenticated by MLB as well. It has a beautiful Mariners 40th Anniversary patch as well. You can verify this information using the MLB hologram number #JC273512. I've included a photo showing Haniger wearing a jersey exactly like this one during the 17' season as well.
