When using a sand wedge for chipping around the green, a short backswing and follow through – with the clubhead accelerating through impact – are bedrock fundamentals.
Also, notice the address position. Open stance… feet close together… ball positioned back in the stance… hands in front of the ball.. shaft tilted towards the target.
Once again, be the GOLFER and not the FAN which is illustrated by her eyes looking down well after impact.
