Popular music historian
Arnold Shaw wrote in 1949 for the
Music Library Association that the term "out of left field" was first used in the idiomatic sense of "from out of nowhere" by the
music industry to refer to a song that unexpectedly performed well in the market. Based on
baseball lingo, a sentence such as "That was a hit out of left field" was used by
song pluggers who promoted recordings and sheet music, to describe a song requiring no effort to sell. In May 1981, Safire asked readers of
The New York Times to send him any ideas they had regarding the origin of the phrase "out of left field"—he did not know where it came from, and did not refer to Shaw's work. On June 28, 1981, he devoted most of his Sunday column to the phrase, offering up various responses he received. The earliest scholarly citation Safire could find was a 1961 article in the journal
American Speech, which defined the variation "out in left field" as meaning "disoriented, out of contact with reality." Linguist
John Algeo told Safire that the phrase most likely came from baseball observers rather than from baseball fans or players. In 1998, American English professor
Robert L. Chapman, in his book
American Slang, wrote that the phrase "out of left field" was in use by 1953. He did not cite Shaw's work and he did not point to printed instances of the phrase in the 1940s. Marcus Callies, an associate professor of English and philology at the
University of Mainz in Germany, wrote that "the precise origin is unclear and disputed", referring to Christine Ammer's conclusion in
The American Heritage Dictionary of Idioms. Callies suggested that the left fielder in baseball might throw the ball to
home plate in an effort to get the runner out before he scores, and that the ball, coming from behind the runner out of left field, would surprise the runner. At the site of the University of Illinois Medical Center in Chicago, Illinois, a 2008 plaque marks the site of the former West Side Park, where the Chicago Cubs played from 1893 to 1915. The plaque states that the location of the county hospital and its psychiatric patients just beyond left field is the origin of the phrase "way out in left field." ==See also==
