Although my ball striking has improved a lot recently, I still hit too many shots with an out to in swingpath. Even when pitching and chipping, I tend to pull the ball somewhat.

I'm a leftie and, with the short irons the divot is pointing well to the right. With longer irons this is not nearly so pronounced for some reason.

I do start the downswing by moving my hips and getting the weight on to the front foot. I don't rush the transition from the top.

I have a suspicion that my shoulders could be returning on too flat a plane. I've noticed that all good ball strikers appear to move the rear shoulder down and and through, rather than around, which is what I think I do. I use the big muscles when pitching and on longer chips, which is why I suspect that my shoulders are the source of the problem.

Does anybody have a practise drill or tip that helps with this correct shoulder movement or technique that produces an in to out swingpath?

Thank you
