The wedges should be used as designed, in other words, the clubs should never be de-lofted. Do not forward lean the club to effectively make a sand-wedge a 7-iron. If you need less loft, change clubs to a lower lofted club.
Use the “bounce” or bottom of the wedge, not the leading edge to deliver the clubhead. This will be more easily accomplished by keeping the club in its neutral attitude, arms hanging naturally and comfortably from the shoulders with the club extending straight down from the hands.
Hold the club’s shaft more vertically than your normal address position – your hands will be slightly higher, perhaps more like the way you stand for putting. This will help rest the clubhead on the ground towards the toe of the club and you’ll want to hit your pitch shots in the area of the clubface from the middle of the face out to the toe. When looking at the bounce on a wedge, there is more bounce at the toe than the heel. Most recreational golfers deliver the clubhead for pitch shots heel first, thus, the lack of bounce combined with a shallow swing path and heel-first delivery leads to digging or “fat” shots. Using the extra bounce the toe area provides will promote a cleaner club delivery and crisp club-on-golf -ball connection.
Finally, keep the scoring lines, or grooves on the clubface up [to the sky] through the hit and into the finish.
