Almost Rdbass .... not 'backwards', as in back towards the catcher ... but more 'rearward', as in fueling a body coil, or 'stretch' (Coil-Stretch-Throw/Swing/Seperate) ... that 'rearward' has a rotational component. In terms of the top hand/arm being in control, the rearward direction may be thought of as towards the third base coach (RH hitter). The loading of the hands governs the 'stretch', or 'body coil' ... and is performed in preparation for the upcoming throw of the barrel.
