I dismiss the premise the game needs to pick up the pace of play. Baseball was not built for constant excitement, and wasn't meant to be on the clock. The only changes I would make is getting rid of the stupid automatic intentional walk, and getting rid of instant replay. Do you want it in the playoffs? Fine, I can compromise there. Otherwise the game is just fine the way it is. Quite honestly, most of the suggestions I've seen here (and other threads where this topic has come up over the years) sound crazy to me. Limiting when you can bring a pitcher in, calling a ball if you throw to first, etc. I can't fathom watching that. You want to speed up the game? Don't make any new rules, just add (or emphasize) an unwritten rule. Make it known to pitchers if they take too long, they may not get calls on the corners. Same thing for batters. Do that, and players will learn to hurry up, believe me.
