Seattle Mariners store bought rookie jersey has a great inscription on the verso. In vintage mint black sharpie it is made out to his first roommate and teammate Alex Diaz. It reads, “Alex, It’s been fun playing with you. Keep having a great career. Your friend, Alex Rodriguez #3.” This is the best A-Rod signed piece we have ever seen and has the rarely if ever seen complete signature he quickly abandoned. Jersey itself is a Diamond Collection teal alternate size 44.
