Don’t try to “make” 30-plus footers. Instead imagine that the hole is in the center of a circle that’s six feet in diameter and leave your lag inside that circle. This removes the pressure to make it so you’ll putt with more feel and less tension in your hands.
Granted I’ve practiced the lob a lot so I can hit it without fear. You should do likewise. Rehearse it often. Get good at it and you won’t be mad when you miss the green. You’ll relish the chance to pull off a jaw-dropping flop that would make Lefty himself tip his cap.
Whether you roll it well and win the game or not so well and lose don’t worry—it’s just practice. Win or lose playing Drawback will hone your touch and feel on the greens which will help you putt better for the rest of the day.
