To beat your slice, you first need to determine if it’s your downswing path or your clubface angle at impact that’s faulty, or both. This can be determined by analyzing your divots and ballflight characteristics. To begin, find a grass practice range and lay a club or piece of colored string along your target line. Once you’re fully warmed up, place a ball on the inside of the club or piece of string and execute a normal, full shot.
If you don’t make solid contact the first time, simply move down the shaft or string and hit another ball from that spot. The key is to hit a shot that represents your “normal” ballflight and to create a clearly recognizable divot in the process. Continue to hit several shots until you feel you’ve made at least a couple of clear divots that have resulted from what you’d consider your typical shots.
