He played as a first baseman in Major League Baseball for the San Diego Padres, San Francisco Giants, Houston Astros, and Detroit Tigers during his career from 1971 to 1983.
In addition to playing first base, Ivie put in considerable time as a third baseman, a left fielder and was a designated hitter.
