 Biographical Information
"Jim Derrington is a 17-year-old whiz of a bonus pitcher . . ." - Sports Illustrated in April 1957
Jim Derrington was the last major league player to break in at the age of 16.
He was the youngest pitcher to start a game, at the age of 16, and may have been the youngest player in the American League to get a hit.
He never played in another major league game after age 17; his minor league career ended when he was just 21. He had a serious arm injury in 1960 so he became a position player for Charleston that year. He learned to throw primarily off-speed pitches but was not as effective in 1961.
He might have made his major league debut at an even earlier age, since he played semi-pro ball at age 13, but a rule at the time required him to play some American Legion ball before he could turn professional.
After baseball he ran a TV/appliance store, managed a produce business and brokered produce. From 1995 on, he coached and managed in independent ball.
