> During the bat/ball impact, they are in contact for only 1/2000 sec. and the bat moves forward only ¾ inch. If this is one the “4 power sources in the swing”, when did this roll of the wrist begin and how does it contribute to a major power increase?

Once again we are talking about the accumulation or storage of power to be released at impact. The bottom hand (left) moves from palm down to a palm up position at follow through. The wrists from a cocked to uncocked position. The sharper the bat-hand angle is, the greater its accumulation of power.
