Of his total 583 career home runs, Mark McGwire hit 363 of them while playing for the Oakland Athletics. In 1987 he was honored with the Rookie of the Year award, the first of many recognitions he would receive during his 16-year career. McGwire will not just go down as one of the greatest home run hitters of all time but as one of the most accomplished athletes in sports history. He finished his memorable career with 12 All-Star Game selections and an induction to the All-Century team. Mark McGwire has hand signed this Red Team USA Jersey. A Steiner Sports Certificate of Authenticity is included.
