Art Ditmar, a right-handed pitcher, spent his Major League Baseball career with the Philadelphia / Kansas City Athletics and the New York Yankees. Born on April 3, 1929, in Winthrop, Massachusetts, Ditmar's journey to the major leagues began when he signed with the Philadelphia Athletics in 1948. He made his MLB debut on July 19, 1954, with the Athletics, who would soon relocate to Kansas City.

During his time with the Athletics, Ditmar showed promise as a pitcher, although the team struggled in the standings. His early years were marked by a learning curve typical for young pitchers, but he gradually found his footing. In 1956, Ditmar was traded to the New York Yankees, a move that would bring him into the spotlight with one of baseball's most storied franchises.

With the Yankees, Ditmar became part of a team that was a perennial contender for the World Series. He played alongside legendary figures such as Mickey Mantle and Yogi Berra, contributing to the Yankees' success during the late 1950s and early 1960s. Ditmar's role with the Yankees was primarily as a starting pitcher, although he also made appearances as a reliever when needed.

One of Ditmar's standout seasons came in 1960 when he posted a 15-9 win-loss record with a 3.06 ERA. That year, the Yankees won the American League pennant, and Ditmar was given the honor of starting Game 1 of the World Series against the Pittsburgh Pirates. Unfortunately, the Yankees lost the series in seven games, with Ditmar taking the loss in Game 1 and again in Game 5.

Despite the World Series setbacks, Ditmar's tenure with the Yankees was marked by consistent performances. He was known for his control on the mound and his ability to keep hitters off balance. His time in New York also included another World Series appearance in 1957, although the Yankees fell to the Milwaukee Braves.

In 1961, Ditmar returned to the Kansas City Athletics as part of a trade. He continued to pitch for the Athletics until the end of his major league career in 1962. Over his career, Ditmar compiled a 72-77 win-loss record, a 3.98 ERA, and 552 strikeouts. While his career statistics may not place him among the all-time greats, Ditmar's years in the majors were marked by steady contributions to his teams.

After retiring from baseball, Ditmar lived a quieter life away from the public eye.
