The cast is an upper body dominant move which results in the following characteristics:
- Spin with upper body and limited use of lower body
- Apply force with arms and hands only and early in transition
- Typical for athletes from other sports
- Outside to inside swing path loses distance (golf digest article - "Add 42 yards now")
- Force applied early in the downswing with the arms instead of letting it build gradually
The cast or upper body dominant swing pattern is one of the most prevalent among higher handicap golfers. A cast happens when the upper body spins to fast, soo soon and dominates transition. This spinning action creates a force that helps propel the arms, hands, and club outward. On 3D I will typically see an early straightening of the trail arm, or an early flexing of the trail wrist. There is also a distinct look to the kinematic sequence for casters.
An athletic move
When it comes to spinning, some athletes have it all figured out. One of the best examples is figure skaters. They build a lot of speed, and then when they want to spin faster, they pull their arms in close. When you let the club head (not your hands in golf) gets far away from you, it’s like the figure skater letting his or her arms go out. This movement SLOWS down rotation. In the golf swing, the timing of when you want the club to get away from you, is through impact.
As you work on impact and follow through, you can start working on the overall feel of the swing which is being narrow in transition, and wide in the follow through. If you are used to playing sports that require a lot of strength, this narrow position will probably feel weak, so initially, you will have to rely on how it looks in your video instead of how it feels in your swing.
A cast is not necessarily bad, unless it is used at the wrong time. The idea time to use a cast sequence is for the short game. If you are a good wedge player, but struggle with distance or with the longer clubs, then there is a good chance that you swing the golf club with a cast or upper body dominant swing pattern.

00:00:00,000 --> 00:00:04,000
In this concept video, we're going to take a look at the cast or the upper body dominance
00:00:04,000 --> 00:00:05,000
00:00:05,000 --> 00:00:12,000
Now the cast or upper body dominance swing pattern is really a transition air, but sometimes
00:00:12,000 --> 00:00:16,000
if it's subtle, you won't see the evidence of the cast until down in the release.
00:00:16,000 --> 00:00:22,000
But overall, it's a transition air, and what it is is getting your upper body too active
00:00:22,000 --> 00:00:23,000
00:00:23,000 --> 00:00:29,000
So if we were to break down your body into thirds, say the hips in the lower body, and then
00:00:29,000 --> 00:00:36,000
the trunk in the core, and then the shoulders and arms, we want to control and create
00:00:36,000 --> 00:00:39,000
our speed from a blend of all three of these.
00:00:39,000 --> 00:00:44,000
The cast pattern is getting speed primarily from the shoulders and the arms early during
00:00:44,000 --> 00:00:45,000
00:00:45,000 --> 00:00:47,000
It shows up pretty easy on 3D.
00:00:47,000 --> 00:00:54,000
It typically looks like the club sensor or the club shaft is moving faster than the rest
00:00:54,000 --> 00:00:58,000
of the body pretty early in the downswing.
00:00:58,000 --> 00:01:04,000
On video, if you see someone who's doing it in more of an exaggerated fashion, what
00:01:04,000 --> 00:01:11,000
will typically look for is a straightening of the trail elbow or a flexion of the trail
00:01:11,000 --> 00:01:17,000
wrist going this way, or an early rotation of the upper body compared to the lower
00:01:17,000 --> 00:01:18,000
00:01:18,000 --> 00:01:22,000
In general, that tends to look like something like this.
00:01:22,000 --> 00:01:29,000
The arms kind of getting active too soon, or it could be more like this where the upper
00:01:29,000 --> 00:01:33,000
body is rotating on top of the lower body and the lower body is not really leading the
00:01:33,000 --> 00:01:34,000
00:01:34,000 --> 00:01:41,000
Either way, it gets the club moving faster than your body, so it tends to limit your ability
00:01:41,000 --> 00:01:43,000
to create speed.
00:01:43,000 --> 00:01:47,000
Typically golfers who cast can have pretty good short games, but they'll struggle off
00:01:47,000 --> 00:01:48,000
00:01:48,000 --> 00:01:52,000
As you'll see in the analysis video, there are a few pros who do it.
00:01:52,000 --> 00:01:55,000
There's even a long drive guy who does it very well.
00:01:55,000 --> 00:02:01,000
But all in all, it tends to be more of a weak controlled pattern as opposed to a maximum
00:02:01,000 --> 00:02:03,000
power generation pattern.
00:02:03,000 --> 00:02:08,000
Now often, the cast is accompanied by something that we call a forward lunge, and you'll
00:02:08,000 --> 00:02:12,000
start to see why these two kind of go hand in hand.
00:02:12,000 --> 00:02:17,000
With the cast pattern, I'm going to get this club head far away from me sooner than if I had
00:02:17,000 --> 00:02:20,000
a normal tour sequence that we tried a tee tier.
00:02:20,000 --> 00:02:25,000
So if I was to get that club away from me, and I did all the other good movements that
00:02:25,000 --> 00:02:29,000
a tour pro would do, I'm typically going to have the club bottom out.
00:02:29,000 --> 00:02:34,000
So the forward lunge is a lack of right side bend and a shift of the upper body kind of
00:02:34,000 --> 00:02:37,000
towards the target kind of like so.
00:02:37,000 --> 00:02:42,000
I'll tend to have my upper body very much on top of my lower body and have a little
00:02:42,000 --> 00:02:43,000
amount of side tilt.
00:02:43,000 --> 00:02:50,000
This prevents me from hitting the ground behind the ball, but it tends to give me a steep
00:02:50,000 --> 00:02:52,000
angle of attack and a very small flat spot.
00:02:52,000 --> 00:02:58,000
So this can result in a lot of problems with your long irons, your hybrids, and particularly
00:02:58,000 --> 00:02:59,000
00:02:59,000 --> 00:03:04,000
Since the cast is a downswing problem, we know that it relates to how we're controlling
00:03:04,000 --> 00:03:08,000
path, how we're controlling face, and how we're creating speed.
00:03:08,000 --> 00:03:13,000
Typically, as I mentioned earlier in this video, it is going to be an upper body dominated
00:03:13,000 --> 00:03:14,000
00:03:14,000 --> 00:03:20,000
So as opposed to getting that initial movement happening from the lower body, I will
00:03:20,000 --> 00:03:25,000
tend to have the initial movement happening more from the upper body kind of like so.
00:03:25,000 --> 00:03:30,000
So one of the ways that you can work on it is by learning to get your lower body to initiate
00:03:30,000 --> 00:03:35,000
and learning to get the feeling of more speed from the lower body.
00:03:35,000 --> 00:03:42,000
Typically, this results in a feeling of a later tempo or typically a smoother swing.
00:03:42,000 --> 00:03:46,000
Now from a face and path perspective, the cast is pretty interesting.
00:03:46,000 --> 00:03:51,000
Typically, what's going on in a cast pattern is you are going to have an open clubface
00:03:51,000 --> 00:03:58,000
that you tend to keep open and you use the cast in order to get the club to go to the left
00:03:58,000 --> 00:04:03,000
or rather to get the path to go to the left so that this open clubface is now pointed
00:04:03,000 --> 00:04:04,000
at the target.
00:04:04,000 --> 00:04:08,000
It is possible to have my body closed enough so that this cast brings it from the inside
00:04:08,000 --> 00:04:10,000
and I can still hit a draw.
00:04:10,000 --> 00:04:15,000
So typically, casters are going to struggle with drawing them all, they'll typically hit
00:04:15,000 --> 00:04:20,000
poles or slight fades unless they're hitting down as they would wish short arms.
00:04:20,000 --> 00:04:25,000
So typically, the way that that's going to look is there my clubface is kind of in an open
00:04:25,000 --> 00:04:26,000
00:04:26,000 --> 00:04:32,000
And now if I was too cast by spinning my upper body and straightening my arms kind of
00:04:32,000 --> 00:04:39,000
like so, you can see that I can get that clubface that is open to the path facing at the
00:04:39,000 --> 00:04:44,000
target by taking this path and moving it a little bit more outside to end.
00:04:44,000 --> 00:04:48,000
That's typically that upper body spin or that upper body dominated pattern.
00:04:48,000 --> 00:04:56,000
Now from a face perspective, getting the club to extend out away from me causes the club
00:04:56,000 --> 00:04:58,000
face to actually want to close.
00:04:58,000 --> 00:05:02,000
The more that I have this club in a lag position or the more that my hands are leading
00:05:02,000 --> 00:05:09,000
the club head, it will tend to force that face open unless I'm doing the motorcycle move,
00:05:09,000 --> 00:05:12,000
which we teach in the transition session.
00:05:12,000 --> 00:05:17,000
So by having that clubface open, if I could either do the motorcycle move to close it or
00:05:17,000 --> 00:05:20,000
I could cast and release that arm.
00:05:20,000 --> 00:05:24,000
And when I release that arm, now the clubface is pointing the direction of the target,
00:05:24,000 --> 00:05:29,000
but I did so with a very vertical shaft as opposed to in the full swing stock program where
00:05:29,000 --> 00:05:34,000
we're trying to have a little bit of shaft lean that would result in an open clubface
00:05:34,000 --> 00:05:38,000
unless I was to close it using this rotation.
00:05:38,000 --> 00:05:44,000
So a castor is typically using the whole shaft to square the clubface instead of just
00:05:44,000 --> 00:05:48,000
shaft rotation to square the clubface.
00:05:48,000 --> 00:05:51,000
If you're going to work on the cast pattern, as you'll see in the drills, there are three
00:05:51,000 --> 00:05:55,000
primary areas that you'll need to improve on.
00:05:55,000 --> 00:06:01,000
One will be getting your arms to lag a little bit and getting the club to be narrow in
00:06:01,000 --> 00:06:02,000
00:06:02,000 --> 00:06:08,000
Two will be getting the club to shallow in transition slightly different way because
00:06:08,000 --> 00:06:11,000
the cast pattern gets the club out of way for me.
00:06:11,000 --> 00:06:17,000
So it creates more of a shallow angle of attack just from the simple fact that I'm getting
00:06:17,000 --> 00:06:19,000
my arms away from me.
00:06:19,000 --> 00:06:23,000
Now it's a little tricky because typically that's accompanied with a deep upper body movement
00:06:23,000 --> 00:06:25,000
so those two balance out.
00:06:25,000 --> 00:06:31,000
So if I'm going to take away the shallow, I need to add a shallow in a different way.
00:06:31,000 --> 00:06:35,000
Lastly, the thing that I'm going to have to do that's probably going to feel the most
00:06:35,000 --> 00:06:40,000
uncomfortable is I'm going to have to create the early part of the downswing speed
00:06:40,000 --> 00:06:45,000
from my lower body and my trunk and my core as opposed to you from my shoulder blades,
00:06:45,000 --> 00:06:48,000
my shoulders and my arms.
00:06:48,000 --> 00:06:51,000
So let's go through those one by one.
00:06:51,000 --> 00:06:52,000
First let's talk about this narrow.
00:06:52,000 --> 00:06:59,000
So if I go up to the top of my swing, the cast pattern tends to get wide very early from the top
00:06:59,000 --> 00:07:00,000
of the swing.
00:07:00,000 --> 00:07:07,000
So the opposite of that would be as my lower body is leading if my arms were to get narrow as we
00:07:07,000 --> 00:07:13,000
teach in the transition sequence and as you'll see in this cast section that allows my body
00:07:13,000 --> 00:07:21,000
to rotate inside then without having my arms extend and bottom out behind the golf ball.
00:07:21,000 --> 00:07:26,000
As a result, my arms will extend a little bit later than in the cast pattern and help me
00:07:26,000 --> 00:07:30,000
produce this more shallow angle of attack with a long flat spot.
00:07:30,000 --> 00:07:33,000
The second piece would be looking at the shallowing component.
00:07:33,000 --> 00:07:40,000
So the shallowing component would be letting my arms fall as a result of my lower body
00:07:40,000 --> 00:07:42,000
leading the golf swing.
00:07:42,000 --> 00:07:47,000
So we talk a lot about those hands staying high and letting this club kind of shallow,
00:07:47,000 --> 00:07:52,000
where a castor will typically shallow by getting the club away from me as opposed to getting
00:07:52,000 --> 00:07:55,000
the swing path of the arms a little bit more horizontal.
00:07:55,000 --> 00:08:00,000
So that's one of the other challenges and then the last one is the general sequencing of learning
00:08:00,000 --> 00:08:03,000
to get that lower body to initiate the downswing.
00:08:03,000 --> 00:08:09,000
Now if you've played sports where it was a reward to be kind of upper body dominant, say you were
00:08:09,000 --> 00:08:14,000
alignment in football or wrestler, something where you did a lot with moving your upper body
00:08:14,000 --> 00:08:18,000
in big movements, this is going to be a little bit of a challenge.
00:08:18,000 --> 00:08:25,000
If you played other sports such as striking sports like tennis, baseball, hockey, lacrosse,
00:08:26,000 --> 00:08:32,000
or if you played lower body dominant sports like soccer, this will tend to feel a little bit more
00:08:32,000 --> 00:08:38,000
athletic and it'll actually be reminiscent of how you use athleticism in those other sports.
00:08:38,000 --> 00:08:43,000
And typically what you'll have to do is remove the barrier of how you control the face and path
00:08:43,000 --> 00:08:51,000
to allow you to be more aggressive with the lower body or to be more athletic and initiate with the
00:08:51,000 --> 00:08:57,000
lower body. So the cast pattern is a great pattern to keep because you want to use it for
00:08:57,000 --> 00:09:01,000
your finesse wedges, your distance wedges, but if you're using it for your stock full swing,
00:09:01,000 --> 00:09:06,000
it's definitely limiting your distance and power potential.
