As i understand it, arm whip is the forearm rotating independently of the upper arm/humerous without coming into contact with the body and brush interference is when the arm comes in contact with the body/leg on its way through the release.

I define whip as the upper arm decelerating as it pauses at the side, allowing the lower arm to accelerate through release. I/R and brush are characteristics of high level whip.

Looks like Scarboroigh is a same (or very similar)
to what I was referring to with Ueno, Cat and Sarah. When I hear the term brush interference. I picture this, almost the arm rolling over the hip. With a generous amount of contact. I do not picture a light brush of the hip as the arm goes by.

I agree. Sure seems to me that what you have described is very prevalent among top pitchers.

The above video of Scarborough got me to looking at my DD's arm. Maybe its wishful thinking but i think they look fairly close. The thing i am curious to know is why my DD's arm kinda "pops" out on the follow through? Could it be due to the hip location/posture at release?

let's add Abbott to that list of pitchers with a lot of interference and the elbow pop.


on a side note, I wonder how bruised her hip got during the learning process with that much power and that much interference. I'm guessing she popped herself real good on more than a few occasions.
