I think we can all agree that the juiced ball just makes everything worse ; fix that problem and the game will readjust somewhat away from the three outcomes. As it stands now, you can’t argue with the mathematical logic of hitters’ approaches, but if the likelihood of hitting a homer goes down, then it relatively raises the value of a single, a steal, or a bunt.
I do not like limits on pitching changes, pick off attempts, outlawing shifts, forcing uniform stadium dimensions, or anything that runs in the face a lot of the historical strategy that makes the game great. If you want to have a lefty specialist, or keep a base runner honest, or build a team to your own park, then go for it!
My outrageous suggestion is to shorten the entire game. I’ve argued this for years, even before bullpenning became a thing. Make the game seven innings (they’ll never do it because it screws up the counting stats) and now we’re looking at 2-2.5 hour games. Starters go 5+ innings before getting yanked while you only have to go back to the 90s for starters to regularly pitch 7+. That will cut down on pitching changes without affecting the overall strategy, and makes for a shorter game! Maybe then my wife would watch with me...
