Julray,
I don’t see Altuve skipping forward. I didn’t watch the entire video. It is natural for back foot to come forward a few inches.
Does Harper’s swing like that on every swing or is this just a case of making a timing adjustment?
When hitting off a tee you shouldn’t have any timing problems that would result in back foot skipping very far.
Harper is early and so Is Cabrera, you can see how far out front Cabrera is making contact.
(Edit: didnt mean to reply to Shawn here. Just in general)
She is ripping it. For sure. I think some front toss would be good(i know hard to do). At least some whiffle balls.
I think her foot is skipping because of that brace(dont worry about it). Dont take too many tee swings. Leave those for us parents.
