My rule IMHO changes....
1) standard fields...
2) only eight pitchers per team, other fielders can pitch
3) move mound back 3 feet
4) on field conferences limited to 20 seconds
5) only one warmup pitch for relief pitcher
6) umpires evaluated for consistency especially balls and strike calling
7) if umpire consistently makes bad calls, umpire goes to the minors
8)slightly heavier baseball
9) 93 feet between bases
10) KEEP FIELDING SHIFTS. Strategic placements of throws, pitches, fielding positions are the best indicators of the thought that goes on in baseball. Sometimes, it is a double dog dare...and that is great.
11) batter cannot leave box for more than 8 seconds
12) pitcher has 18 seconds to pitch
13) Relief pitcher pitches at least two innings or until end of game.
That should speed up the game a bit. IMHO
oh...and kill on field wokeism.
