As far as the african-american percentage, I think the big issue is simply that football and basketball offer greater scholarship opportunities. Black athletes have plenty of opportunity, they just pursue other sports.
The White Sox have Danny Richar, but he's on the disabled list. Pablo Ozuna is a temporary fix until Richar returns.
Baker is an idiot, that we know. Bruce only had a 1/3 season in AAA, so that's not a big deal. Votto should be playing right now, but it's not like Hatteberg is awful. Keeping Votto on the bench though at his age is detrimental.
Wellemeyer gave the Cards a 3.11 ERA right now. Reyes went 2-14 with a 6.04 ERA. I can see why the Cards would be loathe to put Reyes back in. They should trade him.
