Old School;
Do you remember Rudy Jamarillo former batting coach of the Texas Rangers?
I visited Rudy in the batting cages at Arlington Stadium.
He was throwing under handed around the corner of the "L" screen to Rusty Greer.
Rudy was sitting on a chair 20' behind the "L"
screen. Of course the screen full size in front of his face.
This is a reaction drill both for the hitter and the pitcher. There was another
Texas Rangers hitter who had played in Japan. Mentally, I timed the velocity of the batted ball from the impact to the end of the cage. Rusty batted baseball impacted the rear screen quicker than the second hitter.
For a "little guy" Rusty had great bat speed. A White Sox asked me if I could tell "bat speed" over the phone. "I said absolutely"
Bob
agreed I believe I can hear bat speed, especially when they practice with wood.
