So that I clearly understand, are you saying that the bat should be parallel to the ground? Is that what you mean by a level swing?
If that is your contention then I absolutely disagree. I believe that the barrel of the bat should be down at contact. I would further submit that it should never be level because that would indicate that the batter has dropped his lead elbow which creates a linear hand path and loss of power.
I have studied hundreds of MLB clips and the bat barrel is always down at contact on a properly hit ball. I have also studied many, many clips of rec ball batters and the bat barrel is rarely down. It seems the proper swing mechanics are seldom taught to young hitters.
