Maybe that is because there are few black families. No Dad to play catch with in the backyard means all the young black athlete can do is practice his grandstanding for when he makes a tackle or run, basket or rebound.
Add to that the fact that baseball requires a lot of practice and game experience to reach MLB level as compared to someone dropping out of college as an underclassman to enter the NFL or NBA draft and it is easy to see why the black athlete follows the path of least resistance.
More often than not, a baseball player is capable of making a Major League 25 man roster after his 800th to 1000th lifetime game from Little League, Senior League, High school, American Legion through college and/or the minors.
And then there is a little thing called trouble with the curve...
That “no dad to play catch with” reason is faulty. I rarely or never played catch with father (he wasn’t interested), but I played a heck of a lot of baseball when I was a kid. It was my best sport. You played catch with your friends.
