The biggest and nearly ONLY reason for lower scoring in baseball if it is indeed true (I haven't noticed it at all) is:
All the damn relief pitchers entering the games inning after inning.
Every pitcher these days is told to go throw hard and as long as you can, etc.
Complete games by starters are nearly nonexistent.
Now..... almost every time a batter gets in the batter's box he's facing a DIFFERENT PITCHER.
That is BS!
The shift is working now because there is a generation of players playing at the highest level that didn’t have to deal with it on their way up. Now they are having a hard time making the adjustment at the highest level. The owners can’t do anything because they are tied up in contracts, so it makes for ugly baseball until the adjustment is made. It might take years and years, hope they don’t panic and change the rules.
Relief pitching is working because hitters are simply more effective the more a pitcher is seen by them, both because of familiarity with the pitcher and fatigue. It makes for ugly baseball but it works. The more times through an order the worse a pitcher becomes for all but the most elite.
