Thanks, @2022Dad for posting the link. Mostly solid mechanics until the end when your glove side goes out toward 1st. It seems your finish lacks trunk flexion forward and your rotational energy pulls you off the targetline and you don't get flat. Try to finish down the target line with a flat back. Your trunk is not firing properly into release. The towel drill, if executed properly and aggressively could help you with that. Also, more focus on back and core during workouts may help you really get the most from this change.
