Jordan Spieth Golf Swing Analysis


by Robert Cotter (About the Author)
Professional Golf Ball Engineer
Director of Golf Swing Instruction, Instant Golf®

On Sunday, Jordan Spieth won the 2015 U.S. Open Championship by 1 shot over Dustin Johnson and Louis Oosthuizen. His spectacular finish on the controversial Chambers Bay layout secured his 2nd major title of the season as he heads to the Open Championship at St. Andrews in July.

Jordan's last few months on the course have been incredible. In November, he won the Australian Open by 6 shots. Then a week later, he won the Hero World Challenge in Florida by 10 shots, smashing the scoring record at 26 under par. Then in March he won the 2015 Valspar Championship, followed by his dominating 4 stroke win at the Masters Tournament in April.

You may recall that the young phenom Spieth also became the first teenager to win a PGA Tour event since Ralph Guldahl won the Santa Monica Open in 1931. He accomplished this feat when he won an exciting sudden-death playoff on the 5th extra hole at the John Deere Classic in 2013. As a 16 year old he also made the cut at the HP Byron Nelson tournament and finished tied for 16th!

Since turning pro he has been one of the most consistent players on Tour. He had 8 top ten finishes in 2014 and banked over $4 million in on course earnings. He's on fire in 2015 with 11 top ten finishes (including his Valspar, Masters, and U.S. Open wins) in 18 events.

Jordan Spieth and his golf swing are in harmony. He is long off the tee but not among the leaders. However, he is ranked 3rd out of 195 players in Strokes Gained: Tee-To-Green. And his 2015 scoring average per round is an incredible 68.92!

He is also very adept at putting which has him at the top of stats once he is on the green. That means birdies and eagles are dropping for Jordan as evidenced by his impressive total of top 10 finishes.

Now usually when you have a young gun like Jordan the golf swing is powered by the "flexibility of youth". And for those of us over 40 we just don't have the flexibility of a 30 year old, let alone a 21 year old! But Jordan's golf swing has some characteristics that make it very reliable and his swing positions are not back breaking.

In fact much of his golf swing is old school; before the days of "paralysis of analysis" and when cookie cutter swings started to appear.

In this report I look at an aspect of Jordan's golf swing that not only defies modern day convention, but also helps him split fairways and hit greens under pressure. His record, both amateur and professional, is the proof.

Imperfection is perfection...

Though it isn't a perfect circle, the golf swing has a somewhat circular shape. Hence, if you have ever seen an "Iron Byron" or modern ball hitting robot, the shaft and club head revolve around a fixed axis. This is the mechanical ideal.

But with a human golfer it is a different story. Due to the forces created in the swing motion, the anatomy of humans, and equipment parameters, there is a small flat spot at the bottom of the arc in the down swing when a skilled golfer swings a club.


There is also a very powerful throwing out motion of the heavy club head in the down swing that helps a golfer unwind out of the back swing and smash the ball. This allows Jordan to buck convention with his back swing. And therein lies a great tip for us "older" guys.

So let's take a look at Jordan's back swing. The most apparent feature is a Bent Left Arm at the top!:

Jordan Spieth golf swing

That is something you don't see much these days, especially with a flexible young golfer. I would venture to say that less than 1% of modern pros have a bent left arm, it just isn't part of conventional teaching.

Yet it has worked for several great players in the past and present. The guys that immediately come to mind are:

  1. Curtis Strange - Hall of Fame member, 17 PGA wins including two US Opens.
  2. Lee Westwood - Former #1 in the world, 22 European and 2 PGA Tour wins.
  3. Calvin Peete - Vastly underrated star, 12 PGA Tour wins including the 1985 Players Championship (his bent left arm was the result of a childhood accident).

Whether Jordan's softer, slightly bent left arm is a learned orientation or an instinct, it is refreshing to see. There is so much emphasis on perfect positions in the modern game that "feels" or unconventional moves often get lost.

A straight or bent lead (left for a RH golfer) arm is fine as long as that arm is Free of Tension. The straight lead arm concept has been misinterpreted to mean locked or rigid in order to maintain the swing radius. And golfers at all skill levels golfers have suffered the results with non-repeating swings and even physical pain.

Sadly, a tense lead arm kills swing speed, destroys the club head path, and prevents a full release of the club. And under pressure, these effects are magnified for the golfer who attempts to steer a shot or over control the club in order to prevent a mishit. Usually the opposite occurs, and he or she is visiting the woods looking for the ball minutes later.

The Trail and Lead arms have very different roles in the golf swing. But here's a very useful image to help you with the job of the lead arm. Note: This does not apply to the trail arm.

Imagine your Lead Arm is a Piece of Rope:

A rope is passive, at least in regards to starting a motion. It also has no internal structure (skeleton) to make it stiff or rigid. It has to respond to the forces acting on it. I think of it as a "spacer" between the shoulder and grip (see above).

This is part of the reason Jordan and other golfers can play great golf with a bent lead arm. The forces on the lead arm or rope in the down swing will straighten it out at impact. In the case of Calvin Peete, the arm straightened to the limits of his arm's structure, which was basically where it started at address.

The other wonderful aspect of this rope concept is how it contributes to a tension free swing, especially in the down swing. Great players hit fairways and greens on Sunday. Jordan Spieth shot 63 on Sunday at the Australian Open in large part because he limited the tension in his lead arm. His sizzling 64 in the first round of the 2015 Masters was also a result of his rhythmic, unrestricted swing (and hot putter).

A tension free lead arm is part of the equation to a free and full release of the club head through impact. This is true whether you use a traditional straight lead arm or a bent lead arm.

When the golfer learns to stop over extending or locking the elbow on the way to the top, he or she has taken the first step to a more compact, powerful back swing. This is a back swing that will pay huge dividends on the way back to the ball at impact, the moment of truth.

IMPORTANT - "Is it as simple as taking a more compact backswing?"

Absolutely not, and if I could explain this to you right know I would, but this is something you need to see for yourself.


You see there are 3 simple but critical elements to the backswing position in the first picture below.

Without them you have an inefficient swing that produces poor distance and horrible accuracy.

But get them right and all systems are on go for a simple yet powerful return to the back of that ball at impact... and an explosion at impact!

I go into detail in the The Key To A Repeating Golf Swing exactly what these elements are and how to achieve them, and then I show you how to quickly train your body to reproduce them so the downswing swing becomes virtually automatic.

The Key To A Repeating Golf Swing

All great players, past and present, male and female, are performing The Key whether they are consciously aware of it or not.

When The Key is performed correctly, the down swing will be on auto pilot. You will be held captive by your own great swing.

Impact sounds like a gunshot (especially off the driver) and the golf ball is compressed as efficiently as possible. You will use all of your available swing speed with no power leaks, just like Jordan and company.

Hence, the Down Swing has its own Set of Requirements.

The down swing forces created are tremendous, even for the Senior or Slower Swing Speed player. Different muscles are engaged and dynamic balance must be maintained by calling on specific parts of the body. And it all takes place in 1/3 second!

These requirements are met by every pro, yet very few recreational golfers (due to no fault of their own).

That's exactly why I created my blueprint for a true Repeating Golf Swing. A swing that delivers the ball to mowed grass, not the rough or woods.

If you are not happy with your game and are looking for a new direction going forward in 2018, I would like the opportunity to help you by showing you The Key To A Repeating Golf Swing and my complete swing technique.

You will benefit from my firsthand experience inside the ropes, working with some of the top players in the game. I am convinced you will benefit tremendously from my swing instruction, short game strategy, and expert golf ball recommendations (learn more below).

In all my years of playing golf, I have concluded that a golfer can not break 80 without a repeating golf swing. It does not have to be perfect, but it must be reproducible. When a repeating swing takes form, a whole new level of satisfaction results as the golfer is now able to play the game the way it was intended.

My trademark move, The Key, delivers the club head right back through the ball with precision power and control. It is the star of the show. I can't play without it.

In fact my discovery of The Key was the very catalyst for my whole career in the golf industry. It was also the sole factor that..

Took my scores from the 110's to the 70's after struggling for years
with inconsistent ball striking and a stagnant handicap.

I'll show you exactly what I've shown over 10,000 golfers from 61 countries, many of whom broke 80 in their very next round after putting The Key into use.

I have also added some great bonuses to my 2020 complete package including expert, yet brand unbiased new Golf Ball Reviews.

In fact, the following is a note typical of the type that hit my inbox all week. It is genuine and unsolicited:


"First ever even par round"

"Hi Robert,

I just wanted to pass on that over the last few weeks I have being playing better and better, until the peak which was just yesterday.

I played at a local course and for the first time in my life I shot under 80, and not just under. I hit 38, 36. A day of firsts, first ever even par round, first time in the 70's, 4 birdies, just an all round amazing result.

I owe a fair bit of it to you as I am adhering strictly to your teaching.

Thanks again and best regards,

Dale N. - Maylasia

P.S. I have just received 2 dozen (name removed) golf balls, the ball you recommended for my game (although the score yesterday was with a (name removed), needless to say I'm starting to love this ball quite a lot) and the next time out I intend to try this ball. I'll check in with you early in the new year to see if there is anything else that you recommend.


"your instruction clears the head"


"I am sure you have received many testimonials in the past but how many within the first few hours.

I purchased & read your e-book this morning - as usual, after reading I needed to go to the practice range to see if it at least worked sometimes for me before committing any further time - patience is not one of my virtues.

Whilst I hit the ball well & hit what I was aiming at most of the time that is not the reason for this reply.

For the first time in my 40 years of golf I felt & knew at the top when I was in a good position to hit the ball solidly & could predict the outcome from the top of my swing.

In short, thank you - I now have the new sensation of the correct feeling at the top - golf is not a game of perfect but given 5 minutes practice I am convinced that "simple" is the answer for the amateur/social golfer to play good golf without hitting hundreds of balls per day. - your instruction clears the head of the thousand thoughts that ruin scores & a good day out with the boys.

I started a skeptic who expected the same rehash of information, instead I am pleasantly surprised."

Peter V. - Australia

Same day, dramatic improvement... Nice going Peter.

I get notes like these all the time. It doesn't matter whether you are trying to break 105 or 70, the rate of improvement is typically rapid once the "bad data" is stripped from a golfer, and The Key to a repeating golf swing can begin working its magic.
