In this guide, Kerrod Gray explains that topping the golf ball usually stems from an attempt to lift the ball into the air. He demonstrates a specific practice routine involving small swings that emphasize hitting the ball first and the ground second. By focusing on a descending blow and brushing the grass ahead of the ball, golfers can trust the club's loft to do the work.
Golf clubs are designed for a descending blow, hitting the ball first and the turf second.
The loft of the club is what gets the ball airborne; you do not need to 'help' it up.
Focus on making contact with the ground after (in front of) the ball's location.
Start with small swings to build the feel of turf interaction before progressing to full swings.
