My problem with Ozzie's rant is that it was not accurate, at least not in full.
In the AZL every team had not only interpreters but also educators for the Latino players. The players had not only English lessons but also lessons on "social skills" and financial matters. Additionally, most, if not all, the teams had coaching staff who spoke Spanish.
What the White Sox does at the Major level, I can't speak to; but MLB does work with the kids in the minors.
