Gary Cooper's experience in the major leagues wasn't very long — 42 days in 1980, in fact. He played only 21 games for the Atlanta Braves and recorded two plate appearances. Most of his time in The Show was spent as a pinch runner and outfielder.
Cooper was sent back down to the Savannah Braves of the Southern League after his 42nd day in the majors. He would never spend another day in the big leagues..
A year later, after one season with the Durham Bulls in the Carolina League, Cooper retired at the age of 24.
