Try to collapse on the instep of your pivot foot while bending the pivot leg slightly as you progress - stretching out your stride leg down the mound.
Also, as you turn prior to your leg lift, try not to shuffle your pivot foot. Your shifting your entire body to reposition itself, thus having to regain your balance and body weight.
Take notice of how your pivot foot is placed in front of the rubber. Your heel is pointing forward , thus positioning your entire body at extremes to uncoil and regain its balance prior to shifting your weight forward.
There are others who will pickup on mechanics and stuff. But this is what pops out at me at first glance.
