Baseball is a complicated place for black men. The ones in front offices seldom apex to full decision-making power. The ones on coaching staffs rarely rise to the manager's office. And the ones in uniform see that, and see their dwindling numbers on the field, and they talk about it among themselves, just how few faces look like theirs, how sometimes there isn't a single person in whom they can confide the experience of being a black man in America, which, like it or not, is different and is tangible. Inside the Arizona Diamondbacks clubhouse La Russa put together, Rickie Weeks is the lone African-American, one of 25. And this is not rare.
