[O.B.Left]

This is an interesting video of Shawn Clement describing the right arm action as a feeling of hammering a door jam. This does not seem to be a triceps cross line thrust pushing procedure for hitting. Is this a right arm throw with pitch elbow?

Right Arm Throw for sure. Which is akin to a side armed throwing motion.

In line Push Basic is for short shots, chipping , putting but only if you so choose. You can also use a less inline ,( more fanning) motion for Basic as well .......something more like the Right Arm Throw ....see Bat Basic.
