The princess hand refers to how the hand should finish after release and implies IR/forearm fire. Other names I have heard are Kiss the ring, and Drop the mic. Whatever the name the idea is to release the ball low and early and follow through with the rotation of the forearm by finishing open handed, palm facing down.I have No idea about the “princess hand” technique lol, but I do have an 11 minute side by side video analysis from Jillian from fastpitch power I’d be happy to share through email to anyone who’d be interested in seeing it!
