Wondering how many of us, if we came across this player earlier in her career, would have tried to do something to quiet her hands. It's hard to tell from the gif, but looks like she takes her top hand almost completely off the bat several times right up until toe touch.
I do notice her back elbow seems to stay pinned to her side during the swing, it never seems to get near her armpit during the load.
Am I explaining the hands or elbow?
Stance is set up to leak energy up the body early. A little taller and softer stance could help. Load into good posture and stride downhill maintaining good posture. How old is she? Looks to have some pop!
