Playing a chip shot from a greenside uphill lie can be very challenging. First, it may be difficult to establish your stance on the slope. Then, knowing what club to use and gauging how far the ball will fly and roll can be confusing. Here is a simple method for addressing and playing this challenging shot.
When playing from a severe upslope by the green; THE SET UP Play the ball position off of your back foot and stand with your shoulders level to the surface of the green. This will place most of your weight over your back foot where it remains through the entire shot. By keeping your shoulders level to the green surface and playing the ball position back in your stance, you hands will be well ahead of the ball. This effectively DELOFTS the golf club, making it necessary to use a lofted wedge such as your sand or lob wedge. If you do not have a lob wedge, ask your PGA Professional which one is right for you.
THE TAKE AWAY Remaining balanced with your shoulders level, swing the club straight away from the ball. There is no "Up Swing" to this takeaway. Keep the club low, swinging level with your shoulders in a short, flat backswing. No weight shift is needed. "HIT THE HILL" Accelerate forward to the ball on the same level path as the club went away. Don't try to lift into impact; hit hard into the hill and the ball will gently lift over the slope and roll smoothly on the green surface. No traditional follow through finish needed here; keep your weight steady on your back foot and pop the club head into the hill.
