Let's get back to discussing the alternative techniques to the crow hop/bicycle kick...... show more of the "drive through" technique that Amy in AZ referred to.

Harder, more accurate throws to first from the left side of the diamond. https://www.discussfastpitch.com/threads/infield-footwork.30223/
