As hinted at by the photo, that's Baseball America's most recent cover leading up to the baseball's June draft. The excellent Jerry Crasnick has a piece in said issue addressing the topic at hand, which is a possible "scouting bias" against redheads, as odd as that sounds. Here's what Astros GM Jeff Luhnow tells Crasnick:
“The answer could be as simple as the percentage of redheaded people in the population. There just aren't that many out there. If that's the answer, OK. So be it. But there could be something more to it, and if there is, it's certainly worth exploring. Is it because the parts of world where redheaded people typically come from don't play baseball as much and it's not part of the culture? I don't know the answer to that. Is it because they're fair-skinned and not as durable under the sun? I've heard all kinds of crazy theories. I haven't done anything to verify any of them, to be honest with you. But it certainly is an interesting topic.”
Now watch as the Scotts "feed your lawn" guy somehow goes undrafted.
