Babe Ruth's 60 Home Run Season (1927)

In 1927, Babe Ruth set the first truly long-term single season home run standard. However, his first Major League home run record was established during the 1919 season when he connected a then unbelievable twenty-nine times with the Boston Red Sox. The 1919 plateau was considered at the time an "unreachable mark" until the following year when the Bambino smashed his own record by going deep fifty-four times — then beat that record just one year later when he went deep fifty-nine times. A few seasons passed and the 1920 record seemed safe until 1927, when the Sultan of Swat blasted sixty long balls in just one-hundred fifty-one games.
