I fucking hate the DH.
I really fucking hate it, and I'm kind of shocked at the shrug-of-shoulders response in this thread.
A game that uses a DH is not a baseball game. An intrinsic, fundamental aspect of a baseball game is the difficulty in finding and developing players who can do both the offensive side and the defensive side well. Did the Astros get to have Mike Lamb bat in Adam Everett's place every time his turn in the lineup came around? Hell no. But that is the beauty of players like AE. Even if they aren't Honus Wagner or Willie Mays, we appreciate their excellent defense, and it just makes it all the sweeter on the rare occasions that they unexpectedly come through with a big hit (ie. Ausmus in Game 5 of the 2005 NLDS).
The same goes for pitchers. Yes, many of them are awful hitters. Some of them suck at bunting, too, quite frankly. But I loved it when someone like Wandy, or Clemens, or Lima would come up with a hit in a key 2-out situation. I'll bet 90% of MLB pitchers batted 3rd or 4th on their HS team. It's not like these guys are weaklings who don't even know how to hold a bat. I don't care that millionaire pitchers sometimes injure themselves while batting or running the bases. Guys also injure themselves playing with their dog, or their kids, or, uh... washing their truck. It happens.
If no pitchers ever have to bat again, what's next? Will the Red Sox get to put their speedy backup CF in to run for Big Papi when he walks in the 1st inning, and again when he walks in the 5th? The same arguments Calcaterra is using can be applied in a lot of ways. "No one likes to see Big Papi run the bases." That's right, he sucks at running the bases. Another guy would be more entertaining to watch. But it wouldn't be baseball. Colby Rasmus sucks at hitting lefties. Can't we put a RH batter in to face the lefty reliever in the 6th, then put him back in against the righty in the 8th? Colby might even get hurt trying to bat against the lefty! So unfair.
It's hard enough to stomach the Astros being forced to play a game that's not really baseball to me. Seeing it completely take over both leagues would really, really suck, and make me sad.
