do the swivel with the top hand and lead arm EARLY and slow maybe. Do it high- don't drop your hands or upercut the ball. Do it without the shoulders. Do it rythymically so it can be smooth.

practice doing the swivel all the time with half-cuts and dry hacks. make sure you are incorporating enough game speed practicar into your routine. The drills are good, but make sure you are incorporating enough game speed swings with the drilled mechanics and not just relying on the drills to affect your swing. Hit curveballs out front, don't wait on them to break before attacking them.
