What are the grinds and bounces for your 52 and 56? Depending on whether your grind easily allows it, try this approach next time at the pitching practice green:
Take your wedge and open the face. I can get away with about 30 degrees open-ish with my wedges, but each is a 10 bounce, S grind (Callaway’s all-purpose grind. Suitable for Sand.). Yours may not allow what I’d like you to try with it.
Anyway, with that face open 30, point the face at the target. You, OTOH, should have an open stance, more than a normal wedge pitching stance, and about 75% weight or more on the left leg. Ball should be roughly at 1/3 forward in your stance, if 1/2 is in the middle.
We’re trying to both: slide the leading edge under the ball, while still keeping our hands ahead of the clubhead at impact. The club should dig under the ball through impact, and in a soggy lie, is going to make a hell of a mess. So be it.
Takeaway has near immediate wrist-cock, and a lot more backswing length than normal pitches. In my case, I definitely needed to practice this shot a bunch, because it feels like you’re going to send this ball past the next tee, with as far back as you take it. You won’t.
Try to keep the weight on the left side. Should result in a steep backswing, impact underneath and just behind the ball. Keep rotating through the shot.
‘Should’ result in a near vertical launch (I’ve bounced this off ceilings with indoor sims) w/o much spin. Big divot/mess. A lot of height, not a ton of distance, and a ball that won’t check, but also won’t run a ton, absent hitting to a hole running seriously downhill.
Depending on the grind and bounce, see how much opening your club and swing will let you do. I’ve a 588 56 wedge with 14 bounce and a grind where I’ll skull this most times I try it with 30 degrees open. But it works with my 56 with 10 bounce.
