Don’t “stroke” it. Hit a “chip-putt.” From longer range a chipping-type motion gives the shot enough gas. It’s easy: Let your arms swing down from your taller stance. (Save your “stroke” for shorter putts.)
The challenge in hitting this type of wedge shot from a tight lie is to make certain that the bottom of your swing arc is perfectly positioned so that your club kisses the dirt immediately after it makes contact with the ball.
Stop your backswing when the top of your right wrist is about three inches below your belt. Hinge your wrists slightly so that the shaft is a few degrees above parallel to the ground when you end your backswing.
