DD was helping a scout last night/ owner of On Deck Sports. They have a new measuring aid. Similar to a Rev Fire. Shows speed of the ball, revolutions, direction of spin. DD's truest spin direction on her breaking pitches was her screw ball. She found squeezing her ring finger gave her more spin and a slightly better spin direction on the screw. I didn't catch the name of the new ball but I will update as soon as I get her results. Hopefully I can get the link to the product as well.
