Re: Leg spin- follow through/body rotation
No, sorry Dave, I was referring to when the non-bowling arm tucks into the ribs later on in the action. Philpott says that many bowlers let that arm splay out and back before they should, i.e. they start to open their body position too early. He says that the arm tuck should be maintained a fraction longer before the pivot alows the arm to splay away from the body. I don't see any problem with your leading arm at the point in the action you describe.
