In my view, the control segment of the swing by the hands and arms is the first one quarter to one third of the swing. This is what I refer to as swing initiation.

If the bat head extends into the zone in the first quarter of the swing, bat speed has been adjudged to be about 50 mph. Combining the hip turn nearly doubles the bat speed in its flight to contact.

Initiating the swing allowing the bat head to enter the zone in the first quarter of the swing will then end the control phase of the arms in the swing. This would be followed by hip turn increasing bat speed to allow the bat head to act as a projectile into contact.

I'm sorry but this post is a joke. This doesn't even make sense.

You are saying that the bat head gets into the hitting zone first, then the hip turn accelerates the bat further?

What, the bat enters the zone at 50mph (ha) then it just sits there and waits for the hips to catch up and suddenly double its speed? Where you planning or actually hitting the ball?

Something like this?

It's called bat drag and good luck advancing past bronco level pitching. This is nothing like a mlb swing but its what the hands leading the way looks like.

The video posted is a fine example of the drawbacks of the load step.

Also, the video exhibits 'hip drift' or as we used to call it 'stepping in the bucket'.

The swing you show is late with no weight behind it, all arms chasing the hips.

If in fact the swing were initiated right after the stride began, the batter would be propelling the bat with weight shift and hip turn along with the arms.

This swing is again 'all arms'.

Not a very good example.
