I wanted to add a technical postscript to the Eddie Kunz post from this morning. Why should it matter whether a pitcher starts from the stretch taller or bent?
Kunz own answer is that he stays balanced better through the delivery and that’s by far the most important. I had him demonstrate the cascade effect throughout his delivery from altering his beginning. Of course, he’s exaggerating in the pictures below for easy analysis.

In the picture on the left:
- he’s landed closed with his front foot.
-This would sap velocity, and force him to throw across his body, straining his elbow
- His arm is trailing his body significantly
-Leading to pitches up
-His shoulders are to the viewer’s left of his feet.
-Rather than finishing “out front” by driving towards home plate and the viewer, his momentum will carry him across the frame as well
-This will make it much harder or impossible to locate his fastball or throw a slider for a strike
In the picture on the right:
- he’s landed more on line
- look at his hips about to explode towards home plate
- His arm is already up.
- His shoulders are in line with his feet and front leg
- Now he can get his extension out front on fastball and slider
-Now he can command his fastball to both sides
