When you control trajectory and spin rate, you also control distance.Granted you’ll be trying to hit your driver really far to give you a good chance at scoring, but clearly with that notion you might be slightly out of control… why then use the same full swing for your scoring wedges? 

The full swing with scoring wedges will cause your trajectory and spin rate to increase, however, the consistency of both will also decrease.  If we’re trying to control the shot with our scoring wedges, we will need to use a motion that is also more controlled.  We need to use a more balanced swing, rhythmically speaking, where the speeds on both side of the ball are very similar.  This is where the 10 to 2 idea comes into play.
Think of the face on view of your swing which puts your head at 12:00 and your feet at 6:00.  The 10 to 2 swing references the point your hands/arms reach the 10:00 and 2:00 positions.  For a left hander, this shot would be 2 to 10.
This shot will require less hand/wrist action which will help control spin rate and trajectory.  The slower swing speed will also help to decrease both trajectory and spin rate.

When you go to practice this shot your first priority is not how far it goes.  First priority is the rhythm necessary to keep the swing at 10 to 2.  You will find it much easier to hit the 10:00 than the 2:00, which will indicate that the 2:00 is the more important focus.  Once you’ve figured out the 10 to 2 rhythm, start checking your distances with each wedge in your bag.
