Otherwise known as, “The Back-Breaker,” this way of swinging will do exactly that if you’re swinging hard enough.
I have in the past swung from a left-biased address position, but I didn’t do it for long – just long enough to test it out and see what the deal was, and I rejected this way of swinging as a proper method years ago… like, back in 2008.
And while I retained some center-bias in my modeling until 2014, when I re-modeled MCS to one with a right-bias in order to provide a stable head position while swinging, I never did the things Tiger Woods is doing to himself with his return to the “Back-Breaker” swing model.
He started doing this with Sean Foley back in 2010, and I predicted nothing good would come of it – yes, he did win 5 events in ’13 when he was finally healthy enough to play regularly with that swing, but he promptly began to have back issues, culminating in the late ’14 back surgery and his abrupt departure from Foley’s stable.
Here’s a picture of TW from 2001- compare it to him at Torrey Pines a few weeks back:
You can see that in ’01, he still had the slight rightward spine tilt, and he began to drift to the left during the Haney years, but he got all the way there with Foley.
You remember that old saw about “keeping the head stable,” or at least as stable as was possible, during the swing?
Well, watch the below gif. where TW in this swing, has a head that is moving from address to the finish:

I mean, if you watch closely, you’ll see the head is moving right as the club head begins to go back.
Because, even if he doesn’t realize it consciously, TW knows where the head should be at impact, and that’s over the right side, with a rightward spine tilt:
Thing is, if you start the swing with the head left and then have to adjust positions mid-swing to get that right head position, you’re going to be crunching that lower back all day long, until something gives.
That’s why I call a left-biased swing model the “Back-Breaker…”
Back to that head…
From address starting back, it is in constant motion, going back, dropping in the transition, jumping up and back at impact… how are you supposed to do anything with that much head motion during the swing?
Not to mention, this swing looks like a 2/3’s full swing. I know it’s in slow motion, but you can see that there’s no power there, no speed, no anything – he can’t expect to play Tour golf with that swing.
Some serious back-protecting going on there, looks to me.
At least, that’s my conclusion – but we’ve seen him twice this year, and the results were a missed cut and a WD after 18 holes.
I’d say I got it right.
