Carl Alvin Scheib (January 1, 1927 – March 24, 2018)[1] was a professional baseball player, a right-handed pitcher for the Philadelphia Athletics (1943–1945 and 1947–1954) and St. Louis Cardinals (1954) of Major League Baseball (MLB).

Born in Gratz, Pennsylvania, Scheib led the American League in wild pitches with 9 in 1950.

In 1951, Scheib appeared in 46 games as a pitcher, two more as a pinch hitter, and batted .396 (21 for 53).

When Scheib made his first appearance in 1943 at age 16, he was the youngest player in the modern era until Joe Nuxhall debuted with the Cincinnati Reds the following season.

Scheib remains the youngest player in American League history.
