Mickey Mantle with his twin brothers Roy and Ray. The twins were 5 years younger than Mickey. Both Roy and Ray played professional baseball like their older brother. They signed with the New York Yankees in 1954, playing in the minor leagues. However, neither achieved the same level of success as Mickey. Roy played three seasons (1954-1956), hitting .273 with eight home runs, while Ray's minor league career was shorter, spanning parts of two seasons with a .231 average and five home runs.
