Teams have taken the approach of working counts, which leads to more BB and more K. They have decreased BABIP by shifting. OBP and not making an out are more important than AVG. SLG is more important than AVG. These are true because that’s what the math says. “Bullpening” works because that what the math says. Teams are doing these things, and the game looks the way it does, because that is the best way to win ballgames. People who are irritated by this want to make rules to bring the game back to what it was. Only, when exactly is that? The game has looked quite different decade over decade. The game has continually evolved and I think it’s dumb to try to curtail that by adding or changing rules on where players can stand, how often pitching changes can be made, etc. The only rule I think I would entertain is limiting the roster size. So, maybe you have a 25, 26, 27 man roster, but each day you have healthy scratches so only 20 guys are available that day. That could cut down on the bullpening a bit. You could even open it up to the full roster if the game goes extras.
