LOL at this comment. Barry Bonds was arguably the greatest hitter baseball had ever seen after Griffey was slowed by injury.
For all the lip service to Jackie Robinson, I don't think baseball will ever have a huge number of black players. Being athletic is an advantage, but being able to pitch and hit are more important. Blacks excel in the NBA and the NFL because those are more "athletic" sports. Whites do better in the MLB because it doesn't take great athleticism to be a pitcher, and Latinos do well because they spend their entire lives developing the technical aspects of the game.
And, as someone already said, the point is moot ("mute") because its all about ticket prices. The NBA is 80% black, but only white businessmen would be rich/stupid enough to shell out $95 for a 300 level seat.
