Most baseball fans know Tom Candiotti as a knuckleballer but he began his career as a conventional pitcher in 1983--after becoming just the second player to appear in the major leagues following Tommy John surgery, at a time when only Tommy John himself had ever come back from the operation. Candiotti, whose arm recovered, threw fastballs and curveballs in his first two years in the majors before switching over to the knuckleball for the 1986 season. He would then go on to use primarily the knuckleball for the rest of his career, though he threw a good enough curveball to get hitters out.

This biography is based on the recollections of Candiotti himself, his former teammates and managers, newspaper and periodical accounts, and archival resources.
