I can definitely feel your pain. Recently, I had been hitting solid drives (250-265 yards) at the first hole of my home course (Par 4 - 320 yards) leaving me with a 3/4 - full SW into the green. Invariably, at least 30% of the time I would hit the wedge approach shot thin (leading edge) and over the green. After looking at my swing, the club pro recommended that I de-loft the club a bit more by using a bit more forward press and lo and behold, much better results and with a nice divot as well. In fact, the additional forward press has really worked well for my gap wedge and mid-to-low irons as well. Much better ball striking now Another poster also recommended that you slow down your swing which I completely agree with as I found that the slower my takeaway, the better I typically strike the ball. What I have also done when possible is take at least 5 good balls (if no other people are playing behind you of course) and hit them all into that first hole's green at SW distance so that I become very comfortable with that 2nd shot. I repeat until I've made all 5 balls. I find that this, rather than just hitting balls at a target on the range, simulates the pressure of playing an actual hole for a score. Anyway, good luck and keep at it.
