The New York Yankees had a terrible season in 1959, finishing with a 79-75 record and failing to make the playoffs. Yogi Berra (1925-2015), a star player on the club, was quoted in November 1959:
 
“We simply made too many wrong mistakes.”
 
Berra’s quotation is often incorrectly credited to a year later, when the Yankees lost the 1960 World Series to the Pittsburgh Pirates. New York City Mayor John V. Lindsay used “wrong mistakes” in 1968 and U.S. President George H. W. Bush used “wrong mistakes” in 1990, both with a credit to Yogi Berra.

Vin Scully remarked at the beginning of the official World Series film, “What a change of scenery!” This was the only Series from 1949 through 1964 in which no games were played in New York, breaking the streak of the city that documentary filmmaker Ken Burns later called the 1950s’ “Capital of Baseball”.
