Someone did! - and what drag/flat left wrist!

Thanks for this link, mb6606. Tiger's slow motion Iron shot is a 'must see.'

Pause the action at the end of the Follow-Through (the Both Arms Straight position) and note his alignments:

Left Wrist Flat and executing its Horizontal Hinge Action.

Right Wrist Bent.

Clubshaft pointing at the Straight Plane Line.

Classic.

And just how do you produce these alignments in your own Stroke? Do as Tiger is doing:

Drag your 'wet mop' through Impact! [7-19]

Oh, one more thing...

Check out Tiger's strong Finish Swivel as he 'bridges' from Follow-Through to Finish. It just doesn't get any better than this!
