Grab a pencil in your left hand and, pretending it is a zebco 33 fishing rod and reel, make a casting motion straight ahead of you, as if you want to sling the lead point out the end of the pencil, or throw the line of the rod and reel straight out. Hold that position. The wrist should be flat. And when you cocked it up towards your head, the wrist naturally cupped. I got hung up in the flat left wrist business, and lost the ability to play straight golf. To flatten the left wrist on the way to the top severely robs me of angle, and makes me feel I have nothing to hit with through impact. Watch the flat left wrist business. In line cocking and uncocking flattens the lead wrist naturally. Cup back and flatten down. Now get out of here.
