Among the foremost bane of many golfers is the unwanted golf slice. A slice can be caused by many things, but always results in the shot veering hard right (for right-handed golfers) or left (for left-handed players).
It makes staying on the fairway difficult and can lead to major problems off the tee box. Fortunately, there are ways to fix a golf slice.
A weak grip, one that is turned counter-clockwise (clockwise for left-handed players) can cause the clubface to open when the ball is struck, which can cause a slice. To avoid this, try turning the grip a bit to the right (left for left-handed golfers), which will help strengthen the grip. This does not mean to hold the club more strongly, as doing so can also cause a slice.
Speeding up a swing by pulling the club further back before swinging is another way to potentially address a golf slice. Pulling the club back further might also cause the lead elbow to straighten out, which can help keep a ball up the middle while avoiding a slice or hook.
Don't allow the lead elbow to fly away from the body during the backswing or swing. This is called the chicken wing, and it can lead to a wicked slice. Rather, keep the left elbow (right elbow for left-handed golfers) pinned to the body to help keep the swing straight and, therefore, the ball straight as well off the tee or fairway.
Occasionally, a golfer with a bad slice will simply aim their body left (right for left-handed golfers), so that a slice actually ends up in the fairway or on the green.
While this works from time to time, most of the time, aiming one way will open up a stance, which in turn promotes a slice. Rather, keep the body positioned straight to promote a straight shot. Also try dropping the right foot back an inch or two (left foot for lefties), which will help aid a full rotation of the body and help ensure a straighter shot.
A proper swing will feature the clubhead controlled all the way to the point of impact. Any type of lunging or radical motion can cause a slice, as players often overcompensate to hit a quality swing. To keep steady, the club shaft, clubhead and hands should reside directly above the stance line defined by a golfer's feet.
