Davidson's professional career lasted from 1948 through 1957. In 1952, Marlowe, while pitching for the Triple-ABuffalo Bisons, became the second player in International League history to throw a perfect game.[1] After late-season trials with the Tigers in both 1951 and 1952, Marlowe spent the full 1953 and 1954 seasons with Detroit, almost exclusively as a relief pitcher, with only 13 starting assignments in 70 games pitched. He spent most of 1955 and 1956 in the minor leagues. In September 1956, he was claimed off waivers by the White Sox, but worked in only one game for them, his last MLB appearance on September 30.
