Alex Rodriguez the three-time MVP wore this size ���50��� jersey during his first season in the Big Apple ��� 2004. A-Rod held up well in that crucible known as Yankee Stadium. A.286 average, 36 home runs and 106 RBIs, typical A-Rod numbers, all point to his consistency. The offered jersey, authenticated with a signed letter by A-Rod, is the first-known Yankee jersey with the superstar���s validation. Wonderful use is exhibited with light puckering on the two-color tackle twill identifiers and great label wear is evident. Midnight navy blue and white ribbing surrounds the sleeves. Pilling appears below ���YORK��� on the front. Sewn in the tail is a Russell Athletic tag and two suspended flag designators: fabric/size and ���+2? Body Length.��� Both flag tags have curled from washings. This garment may be confirmed to 2004, because in 2005 the Yankees adopted (exclusively) Majestic-made jerseys. A-Rod signed the verso in blue felt tip. Accompanied by a Letter of Authenticity signed by Alex Rordriguez himself (the signature on the LOA itself is certified by PSA/DNA) to attest to the game usage and accompanied by a Letter of Grading & Authenticity from PSA/DNA, with the jersey's bold blue autograph receiving a solid MINT 9 grade!
