[Bagger Lance]

Left arm rotates according to the rhythm of the stroke, i.e. hinge action accompanied by a hands controlled pivot.

Don't fall into the position golf trap. There is rhythm and pace of the stroke. You must have both from putt to drive. You don't have to intentionally "do" a flat left wrist roll on the downstroke, but you must be aware of it and set up for it. Remember on a full stroke that the shoulder turn is rotating at least 45 degrees from the top of the stroke to impact.

When discussing turn, roll, and hinge action, Homer did say that it was "easier for him" to take the club away (turn) in the same manner he wanted it to roll on the downstroke. (my words).

All that matters is the 3/4th of an inch during impact and the smooth motion that got you through it.

Flat left wrist, smooth rhythm, straight plane line, and a planned hinge action.

Any course, any time.
