Swing 1.0: wrists closed at top of backswing

Just watched a youtube swing vision of Zack Johnson and the commentator said that his club face pointed up to the sky at the top of his backswing. In other words it was closed. I tried this on the practice net and it seems like it really closes my clubface at impact. Which allows me to have greater lag which is what I've been trying to have but every time I do that I push the ball way right. Then I would have to really think about releasing the club head to compensate which is not what I want to do. So this might help me. I'll have to try this out, look at other players and think about this.

Just another tiny thing to discover which can completely change your swing!
