Baseball - micromanaged?

How micro is baseball managed? Is someone making a decision on -

  • which pitch to throw?

  • where / when / how the batter swings?

  • from pitch to pitch?

I usually just see the manager sitting there, not giving signs or instructions from pitch to pitch. Or is another coach/manager “calling the plays” to use a football term?

This varies tremendously from team to team and level to level. Some coaches/managers call every pitch. As one who has coached soccer, baseball, and basketball, I can tell you that the most “coach-driven” of the three is baseball; the least is soccer, and basketball is somewhere between, but closer to soccer than baseball.
