[O.B.Left]

How does the pulling motion in the down stroke by a swinger work? Isn't this a left arm action?

When Swinging , for pivot strokes there is no "left arm pulling action". That is to say the left arm is inert, string like and is pulled by the left shoulder only. For a swingers Pull Minor Basic , one accumulator, stroke , the Pivot is zeroed and the Left Arm itself does the pulling . You don't see this shot on tv very often but it is a logical shot given Homers catalogue of available options. Dave Stockton putts this way apparently despite the fact he sets up like he's about to Push Basic .

Think about this way ... to pull with the left arm in a pivot stroke is to pull the left arm away from the chest, an early release of #4. Hmmm not sure about short Full Sweep Release Pivot Strokes .... there might be a little left arm pulling there, gotta check that out on the range. Yoda'd know, he is a magician with that shot. Luke Donald isn't bad at it either.
