In 1987, he set a single-season home run record for rookies with 49 with Oakland and was selected AL Rookie of the Year. He averaged a home run every 10.61 at bats, the best at bats per home run ratio in Major League history.
A native of Pomona, Calif., and All-American at USC, McGwire was a key member of Oakland’s 1989 World Championship team.
