The 10-year period between 1955 and 1964 was, quite likely, the most successful in Yankees history. They made an incredible nine (!) World Series in 10 years, winning four and losing five, and boasted some elite talent on their rosters every year.
That 1964 season, which ended in a Fall Classic loss, marked the end of an era. From 1965 until 1976, the franchise wouldn’t appear in another World Series. In the late 60s, many Hall of Famers retired — Whitey Ford did so in 1967, and Elston Howard and Mickey Mantle said goodbye a year later — and a transition period ensued.
