Positions played by African-Americans in the MLB 1947-2012

The chart above shows us the way Black players were able to reach the MLB and that was nearly exclusively in the outfield for position players, with several years actually having no Black MLB catchers. Outfield makes up 33% of MLB positions and yet 60% of Black players who made the MLB since the mid-1960s have been outfielders.
