This replica home jersey for the Yankees' Shelly Duncan comes hand-signed and with a Steiner Sports certificate of authenticity.

The legend of Shelley Duncan continues to grow each day. The son of Cardinals pitching coach Dave Duncan and brother of Cardinals player Chris Duncan, made his MLB debut with the New York Yankees on July 20, 2007, as the designated hitter against the Tampa Bay Devil Rays, recording his first career hit and RBI. The next day, he hit his first major league home run against the Devil Rays, and the following day had his first multi-home run game, going deep twice at Yankee Stadium.

Duncan, who spent six years in the minors, looks likely to stick around the Bronx for a long time as a DH, first baseman, outfielder and pinch hitter.
