1) Know what a tired pitcher looks like.
2) Know how to play matchups.
3) Put the players recently called up from the minors in the lineup and at their natural position.
4) Communicate with players so there are no unnecessary surprises for them, esp. when the front office has a "lapse" in communication.
5) Know the profile for a leadoff hitter.
6) Coach proactively. If the front office has to step in to solve a problem, you lose that player to the minors, a release, or a trade.
This feels all like basic stuff that I shouldn't have to mention.
Note that analytics isn't anywhere on this list. If you can't do the basic stuff nothing else matters.
