Its part of the game right from Little League, it should stay that way.
Nope, it's not "part of the game". There are five minor league levels -- rookie, A, Advanced A, AA and AAA. Pitchers do not hit in the lower three levels. And games between AL farm clubs at the AA and AAA levels employ the DH.
At the professional level, the pitcher-as-hitter is the exception rather than the rule.
I stand corrected then.
To me, having a DH just takes something away from the integrity of the game.
Having the pitcher hit is one more variable that would make baseball less predictable and thereby more interesting.
Yep and I don't like it. I went to a minor league game and it's not as interesting that there's less strategy involved.
