Op wants to play tball
I don’t get it.  Pitchers have to throw strikes so they’re automatically obligated to throw it in the strike zone. >

The strike zone is still fairly consistent. The only guessing is what the specific umpire defines as the strike zone, and teams have plently of data on that from the many previous games that specific umpires will call. 
Pitchers are still incentivized to throw strikes, or else they’ll end up walking batters. That doesn’t mean pitchers want to throw meatballs down the middle, that would just be gifting hits to the opposing team. >

The whole point of the game is to stop your opponent from scoring. The best way to do that is to throw pitches they can't hit. Throwing pitches that are easy to hit doesn't help you in any way.
