The Boston Red Sox are a professional baseball team founded in Boston, Massachusetts in 1901. They are a member and current champions of the Major League Baseball’s American League Eastern Division and of the American League. The Boston Red Sox have played in Fenway Park since 1912. Their name the "Red Sox" comes from the iconic uniform feature and they are nicknamed the BoSox, Olde Towne Team and the Crimson Hose, but most fans calles them the Sox. To 1918 they won four championships and after that they went into one of the longest championship droughts in baseball history. In the 1920s and 1930s the Boston Red Sox finished in the second division with very poor records.

However, when Tom Yawkey bought the Red Sox in 1933, things began to change and the Red Sox were once again competitive in the late thirties. In 1948 and 1949 the narrowly lost the AL pennant. Four teams were in the AL pennant race until almost the last game in the 1967 season and is remembered as one of the great pennant races in baseball history because of that. After the 1983 season, the Red Soxes posted their worst record since 1966 finishing sixth in the seven-team AL East. In 2004 Sports Illustrated named the Boston Red Sox the 2004 Sportsmen of the Year. The Red Sox lead all MLB teams in average road attendance in 2007, while the small capacity of Fenway caused them to rank 11th in home attendance.
