The progression of the pitcher is fun to watch once it clicks.True. But how many PCs are out there that don’t stress the mechanics. They stress speed. It took 2 years for us to realize what good mechanics were. Like another PC in our area guns every pitch, but doesn’t stress mechanics.
Early on walks greater than the K
A year into into the walks drop and K's almost equal
2-3 years later the K's over take the BB 12U age
By 16U-18U the K/BB 5+/1
All goes back to foundation, mechanics and growth. Mine had a similar path like what you stated earlier.
