If I could make one rule change (on the field) in baseball, it would be to limit the number of pitching changes during an inning. My favored version would be that a pitcher cannot be removed during the inning unless he meets one of the following criteria:
1. He has pitched at least one full inning.
2. He has allowed at least one run (charged to him, inherited runs do not count).
3. He is hurt (we could make some rule to prevent abuse, for instance that the pitcher can’t pitch for the next two days, or the other team gets to choose the reliever who replaces him, or he has to go on the DL after the game even if he feels fine.)
One advantage of this would be that the games would be a lot more interesting and a lot shorter without all the incessant pitching changes. Also, it would annoy Tony LaRussa. Finally, it would probably cause teams to stop carrying so many relievers, which allows for more pinch-hitters, who are more interesting than relievers. Also, if you’re an owner, those pinch-hitters will probably make the minimum while your LOOGY is signed to a two-year, $1.7 million contract.
