Charles James Derrington (born November 29, 1939) is an American former professional baseball player.
A left-handed pitcher, he spent parts of the 1956 and 1957 seasons as a member of the Chicago White Sox.
Derrington first appeared in semi-professional baseball at age 13 and was a high school star at age 16 as a hitter and a pitcher, winning a local player of the year award.
Graduating at an early age, he signed with the White Sox for one of the largest bonuses of his time in 1956.
Under the bonus rule of the time, he joined the White Sox immediately and went on to start their final game of the 1956 season, becoming the youngest pitcher to do so in the 20th century, and stayed with the team throughout the 1957 campaign.
Sent back to the minor leagues in 1958, Derrington suffered an elbow injury that ultimately ended his professional career before age 22.
