He was a knuckleball-throwing pitcher in the Major Leagues for all or parts of seven seasons between 1955 and 1965 for the St. Louis Cardinals, Detroit Tigers and Chicago Cubs.

Born in Beverly, New Jersey, he threw and batted right-handed, stood 6 feet 2 inches (1.88 m) tall and weighed 200 pounds (91 kg).

He had two good years with the Cubs, then was traded to the Cardinals where he had his best season, 1964, with 14 saves (a significant quantity in those days) and a 1.64 earned run average.

In between, Schultz played winter ball in Venezuela for the Gavilanes de Maracaibo club of the Western Professional Baseball League, where he won seven consecutive strikeout titles from 1954 through 1960.

Schultz was a resident of Edgewater Park, New Jersey, where his home was filled with memorabilia of his baseball career.
