Richard Carter Wantz (April 11, 1940 – May 13, 1965) was an American professional baseball player whose life and Major League career were cut short when he was felled by a fatal brain tumor.
A right-handed relief pitcher and a rookie member of the Los Angeles Angels in 1965, he was stricken mere days after his April 13 MLB debut, the only appearance he would be able to make in the majors.
