Art Ditmar (born April 3, 1929 in Winthrop, Massachusetts) is a former starting pitcher in Major League Baseball who played for the Athletics (Philadelphia, 1954 - Kansas City, 1955-56, 1961-62) and the New York Yankees (1957-1961). He batted and threw right-handed. A finesse control pitcher, Ditmar divided his career between the Athletics and Yankees. He didn't considered himself a power pitcher, yet the variable-speed fastball was his most common oferring. He also had a slider and a good curveball.
Ditmar won 47 games for the Yankees in a span of five years, with a career-high 15 in 1960, despite he didn't get to pitch on a regular basis in a rotation that included Whitey Ford, Bobby Shantz, Don Larsen and Bob Turley.
In a nine-season career, Ditmar compiled a 72-77 record with 552 strikeouts and a 3.98 ERA in 1268.0 innings.
