Bobby Shantz is a former Major League Baseball pitcher for the Philadelphia Athletics (1949–1954), Kansas City Athletics (1955–1956), New York Yankees (1957–1960), Pittsburgh Pirates (1961), Houston Colt .45's (1962), St. Louis Cardinals (1962–1964), Chicago Cubs (1964), and the Philadelphia Phillies (1964).
A left-hander, Shantz began his career as a starting pitcher, but about halfway through he converted to a competent relief pitcher. In 1951 he added the knuckleball to his repertoire. Standing only 5 ft 6 in (1.68 m), Shantz had a career record of 119 games won, 99 games lost, and an earned run average of 3.38.
Shantz enjoyed his best season in 1952 when he led the American League in wins (24) and won the MVP Award. A highly skilled fielder, Shantz won eight consecutive Gold Glove Awards from 1957 to 1964. Shantz also was selected for the All-Star Game in 1951, 1952 and 1957. In the fifth and final inning of the 1952 All Star Game, the left–handed Shantz exhibited his distinctive sidearm delivery and sharp curve and control and struck out three consecutive National League hitters: Whitey Lockman, Jackie Robinson and Stan Musial.
Shantz appeared in relief three games each in the 1957 and 1960 World Series with the Casey Stengel managed New York Yankees.
Shantz had the distinction of being selected in expansion drafts in consecutive seasons. He was selected in the 1960 MLB expansion draft by the Washington Senators from the New York Yankees, and in the 1961 MLB expansion draft by the Colt .45s from the Pittsburgh Pirates.
