the first hispanic voted into baseballs hall of fame was Roberto Clemente
That was Roberto Clemente of Puerto Rico who was inducted, posthumously, in 1973. Actually, Ted Williams was the first Hispanic baseball player inducted into the Hall of Fame, when he was elected in 1966. Williams' mother was born in Ciudad Juarez, Mexico.
Jaun Marichal Only Hispanic Player in the MLB Hall Of Fame
That would be Roberto Clemente, elected in 1973 soon after his tragic death. (The 5-year waiting period was waived.) The first Hispanic player elected not on a special consideration would be Al Lopez, a catcher as a player but elected primarily for his achievements as a manager. Lopez joined the HOF in 1977, which would have been before Clemente would normally have been eligible, perhaps even before Clemente would have retired. The first Hispanic player other than Clemente elected strictly for his performance on the field was Juan Marichal, a native of the Dominican Republic and the pitcher who won the most games during the 1960s (191). Marichal was elected to the HOF in 1983.
