Until we started getting real slow video evidence of what MLB Hitters are actually doing the mechanics of hitting were being taught the opposite...
Evidence shows that many more hitters in MLB use a "rotational" approach to hitting over a "linear" After seeing enough video of what MLB hitters are doing I am convinced that this is what we need to teach our hitters...Not a huge difference to what I thought before but the main idea of getting into slot/plane early is more benefecial to not only Power but consistency
Many of the buzz words and drills I have been preaching to the Sandlot Hitters is with this concept in mind.
Shaft to Shoulder with knob pointing at pitcher
Getting in Slot Early
Bat in hitting zone as long as possible
Short into slot/plane and long through
Letting hips and larger muscle groups control the hands more
Hitting off a firm front side
Getting on same plane as pitch (you actually go a little uphill a lot of times but not verbally telling young hitters this)
