> Sorry, but you will have to explain the “Thumb base” grip to me. --- From pre-launch until the elbow lowers to the side, the top-hand is pulling back on the bat with only the fingers. Therefore, the batter does not actually need to grip (close the hand tightly) with the top-hand. Holding the bat loosely in the top-hand while applying THT reduces the occurrence of wrist binds and waves in the swing plane.

Thumb base is very low on the thumb into what you might consider outer palm - in my hand about 2 inches away from the middle of the palm. Orienting the top hand such that this thumb base curls around the handle, I find this can be a good source of primary pressure. Fingers assist and add stability.
