Here's a recent discussion that might be interesting:

"Baseball is an expensive sport: Many play year-round, spending as much as $4,000 to play in the winter. They return to their high school teams more polished—and more likely to get playing time—than the kids who can’t afford the extra coaching. According to the Brookings Institution, the average net worth of a white family in 2016 was $171,000. The average net worth of a Black family was $17,150. That alone puts young Black players at a disadvantage."
Does this mean that all white people have more money than all Black people? It does not. Does it mean that the system is full of white people actively working to keep Black people out of the sport? It does not. Does it mean that, overall, white people have an advantage that Black people don't because wealth in this country is tied to race? Yes. It's systemic, not based on intentionally racist actions by individuals.
Also, there's research on whether race affects rookie card values for Hall of Fame players. Google "Race, performance, and baseball card values" and you should get it.
