Most golfers reach for the sand wedge when reaching the green no matter the position of the shot. Sometimes loft is needed but if you just need to roll or bump the ball forward use less loft like a 9 iron or less. Use your putting grip, lean the shaft forward slightly and make the stroke with your chest and shoulders much like a putt. Try to keep the club low to the ground with even pace and length. Try a few different clubs until you find the one that works best for you and then use this club every time you are faced with this shot. Good luck and keep the ball and club low!
