Pettersson's "Sway"

After going to see the very last round on the CIMB Classic, Ramzi had requested about Dufner's waggle -- which I wrote approximately the previous day -- and also approximately Carl Pettersson's apparent sway. Ramzi commented:

Also noticed Carl Petterson teeing off, he became expectantly hitting/tapping on pinnacle of the ball to get the proper tee peak. He additionally has this quasi-sway to the proper whilst he starts his backswing. Why does he do this?

Here's what I wrote back in the comments:

As for Carl, that isn't always a sway. He's shifting behind the ball -- a circulate that Carl Rabito, the PGA teaching pro who taught me, also teaches. I normally do not teach it due to the fact I suppose you both do it evidently whilst you try to stay constant over the ball otherwise you emerge as with a full-blown sway. I found a YouTube video with the aid of PGA coaching seasoned Brian Manzella that demonstrates it. It's within the first couple of minutes.

And here's that video I mentioned:

Just to make matters clean, here are multiple films of Carl swinging an iron from barely different angles. The purpose for the second becomes clean shortly:

The simplest manner I may want to think of to reveal Carl's circulate is with a "time-lapse" image. First I took stills of his cope with, pinnacle of backswing function, and just after effect. Then I layered them, made sure his toes have been in the same location in all three, and faded them collectively. Here's the result:

If you look closely, you can see that most of the side-to-side movement is with his hips. His head is tallest at address, then moves slightly downward as his hips swing backward, then turns toward the target as he makes his downswing. His head really doesn't move much, and that's why I included the second video -- from the angle it was shot, you can see just how much his head turns during his swing. It's that head turn that makes it look like he moves so much.

In Carl's case, this hip motion also contributes to that little out-to-in move in his downswing. (No, it is now not surely an over-the-pinnacle flow because his fingers do not flow outward towards the ball until AFTER he starts down. In an over-the-top swing, the hands circulate outward while the fingers are nevertheless going up.)

I suppose Carl makes this flow due to the fact he isn't always as flexible as some other players. If you watch the videos, you could see his left heel come off the floor before he ever reaches the top of his backswing. (You Stack'n'Tilters available can go away a remark if I'm wrong, but his move actually jogs my memory a bit of the S'n'T hip pass. His head remains fairly focused -- in his case, just behind the ball -- at the same time as his decrease body moves pretty a chunk lower back and through.)

The key to his success here is that his head stays in pretty much the same vertical position throughout his swing, despite the way it looks. It's a slightly unorthodox move but it's repeatable for Carl. I think it's his adaptation to his inflexibility... and it works very well indeed.
