Daniel Ponce de Leon talks about how a $6000 investment in training at Driveline Baseball helped his delivery:
What he learned from the scan confirmed his suspicions. Ponce de Leon, 28, felt that his delivery had gone astray, tracing its erosion to soreness in his lower back. He did not know how to get the delivery untracked, and counted on Driveline to give him a plan. He used the tech to see his foot strike on the mound, his shoulder rotation, hip rotation, and elbow extension — and looking at that kinetic chain saw where his hips lagged behind. He also saw how to correct it.
Driveline gave him a series of drills to do, touchstones he can return to if he feels the delivery drifting, and Driveline coordinated an individual instructor he could contact throughout the winter for guidance.

I like this article better than the usual “best shape of my life” articles because it points to actual analysis and changes based on that analysis that are working. He pitched five scoreless innings so far this spring with nine strikeouts and one walk.
