Mark McGwire has hand signed this MLB baseball and added the inscribed "ROY/49 HR, " commemorating the Rookie of the Year award he won in Oakland in 1987 and the 49 home runs he hit. McGwire went on to win the American League Gold Glove award and was inducted to the All-Century team. Mark 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.
