John Michael Pesky, nicknamed "the Needle" and "Mr. Red Sox", was an American professional baseball player, manager and coach. He was a shortstop and third baseman during a ten-year major league playing career, appearing in 1,270 games played in 1942 and from 1946 to 1954 for three teams. He missed the 1943–45 seasons while serving in World War II. Pesky was associated with the Boston Red Sox for 61 of his 73 years in baseball—from 1940 through June 3, 1952, 1961 through 1964, and from 1969 until his death. Pesky also managed the Red Sox from 1963 to 1964, and in September 1980.

The Boston Red Sox are an American professional baseball team based in Boston. The Red Sox compete in Major League Baseball (MLB) as a member club of the American League (AL) East Division. Founded in 1901 as one of the American League's eight charter franchises, the team's home ballpark has been Fenway Park since 1912. The "Red Sox" name was chosen by the team owner, John I. Taylor, c. 1908, following the lead of previous teams that had been known as the "Boston Red Stockings", including the Boston Braves. The team has won nine World Series championships, tied for the third-most of any MLB team, and has played in 13 World Series. Their most recent World Series appearance and win was in 2018. In addition, they won the 1904 American League pennant, but were not able to defend their 1903 World Series championship when the New York Giants refused to participate in the 1904 World Series.
