00:00:00,000 --> 00:00:09,000
In this analysis video, we're going to discuss the cast pattern.

00:00:09,000 --> 00:00:13,000
Our definition of the cast isn't early straightening of the trail arm.

00:00:13,000 --> 00:00:19,000
This can either be from the elbow, as demonstrated here on the left, or this could be

00:00:19,000 --> 00:00:25,000
from the wrist, as demonstrated here on the right.

00:00:25,000 --> 00:00:29,000
The most conventional and easiest way to look at the cast pattern is from the space

00:00:29,000 --> 00:00:30,000
on view.

00:00:30,000 --> 00:00:36,000
What you can typically look at is the angle between the left forearm and the club, or you

00:00:36,000 --> 00:00:44,000
can look at the space between the club and the body, such as that space there.

00:00:44,000 --> 00:00:50,000
What you will see on the cast pattern is that space is going to tend to increase where that

00:00:50,000 --> 00:00:56,000
angle is going to decrease more or less straight from the top of the swing, or at least

00:00:56,000 --> 00:00:59,000
before parallels the leg ground.

00:00:59,000 --> 00:01:03,000
On the right, you'll see a little bit more subtle change because the cast is happening more

00:01:03,000 --> 00:01:07,000
from the wrist than it is from the elbow.

00:01:07,000 --> 00:01:11,000
Sometimes the cast pattern is hard to see if it is occurring more from the trail wrist than

00:01:11,000 --> 00:01:13,000
the trail elbow.

00:01:13,000 --> 00:01:16,000
One easy way to look at it.

00:01:16,000 --> 00:01:20,000
The easiest way to look at it would be on 3D, but one way to look at it on video.

00:01:20,000 --> 00:01:26,000
One way to look at the top of the swing, and if you were to just analyze or look at the

00:01:26,000 --> 00:01:32,000
amount or the angle of that trail wrist, if you were then to bring the club down until

00:01:32,000 --> 00:01:40,000
it's just in delivery position or until it's about waist height, if that angle has decreased,

00:01:40,000 --> 00:01:44,000
then there's a good chance that this player has cast.

00:01:44,000 --> 00:01:50,000
Most players with an efficient release are going to maintain or at least increase the amount

00:01:50,000 --> 00:01:54,000
of hinge or extension in that trail wrist.

00:01:54,000 --> 00:01:55,000
Here's another example.

00:01:55,000 --> 00:02:01,000
You can see the amount or the angle roughly there.

00:02:01,000 --> 00:02:09,000
If we were to bring the scalper down to waist height, you can see that most of that angle

00:02:09,000 --> 00:02:14,000
is gone and you can see if we go one or two more frames, it's almost completely gone.

00:02:14,000 --> 00:02:17,000
That's a clear evidence of a cast pattern.

00:02:17,000 --> 00:02:24,000
Frequently, the cast is described as an unhinging of the wrist or an older deviation,

00:02:24,000 --> 00:02:29,000
which would be essentially extending your wrist like you're using a hammer, pointing it

00:02:29,000 --> 00:02:31,000
out that way.

00:02:31,000 --> 00:02:37,000
From what I've seen on 3D, it is very possible to not unhing yet still cast, which is why

00:02:37,000 --> 00:02:43,000
we define the cast as a movement from either the elbow or trail wrist flexion early in

00:02:43,000 --> 00:02:46,000
the downswing.

00:02:46,000 --> 00:02:53,000
From not 100%, the typical pattern for a cast is going to be complaining of distance or

00:02:53,000 --> 00:02:56,000
feeling that they're weak.

00:02:56,000 --> 00:03:01,000
They will typically have trouble hitting them more than about 250.

00:03:01,000 --> 00:03:03,000
Good wedge players.

00:03:03,000 --> 00:03:07,000
Typically bad drivers of the golf ball, and their wrist pattern will typically be more

00:03:07,000 --> 00:03:13,000
on the toe as opposed to the heel.

00:03:13,000 --> 00:03:18,000
Let's take a look at one of the most prominent casters who ever played the game.

00:03:18,000 --> 00:03:22,000
His name would be Nick Faldo, and I probably wouldn't have known that he was a castor if

00:03:22,000 --> 00:03:28,000
I hadn't seen the wrist graphs for his 3D, but it does make sense with the pattern given

00:03:28,000 --> 00:03:33,000
the fact that distance was always one of his issues.

00:03:33,000 --> 00:03:40,000
He is more of a wrist castor, so from the face on view, the cast will be very subtle.

00:03:40,000 --> 00:03:46,000
He actually loads his elbow, but unloads his wrist straight from the top of the swing.

00:03:46,000 --> 00:03:55,000
If we were to look at the angle, we may be slightly confused, because if I bring him down

00:03:55,000 --> 00:04:02,000
say to there, it gives the appearance that he has increased the angle, which he has.

00:04:02,000 --> 00:04:08,000
He has actually increased the amount of hinge in his wrist, but if we were to look from

00:04:08,000 --> 00:04:13,000
this down the line view in the way that I showed you during the definition section,

00:04:13,000 --> 00:04:19,000
you can see a subtle, and gradual, unloading of the right wrist to the point where when

00:04:19,000 --> 00:04:26,000
he gets to this waist type position, that right wrist is relatively straight compared to

00:04:26,000 --> 00:04:29,000
where it was at the top of the swing.

00:04:29,000 --> 00:04:37,000
It's just a slow, gradual, unhinging or flexing of that right wrist that produces his cast

00:04:37,000 --> 00:04:41,000
pattern, which is part of the reason why, even though he produces a path that's very

00:04:41,000 --> 00:04:46,000
good and a face point where he wants to, he struggles with distance.

00:04:46,000 --> 00:04:50,000
Now I don't want you to think that cast patterns can't hit the ball far, it's just

00:04:50,000 --> 00:04:52,000
the common pattern that they don't.

00:04:52,000 --> 00:04:57,000
Here's another golfer, Jason Zubak, who does have a tendency towards this cast pattern.

00:04:57,000 --> 00:05:03,000
If you're to look on at his face on view, and we were to draw this angle, you can see

00:05:03,000 --> 00:05:13,000
that early in the downswing he's going to release a good bit of that angle.

00:05:13,000 --> 00:05:18,000
Right about here, this is not the best camera angle for looking at it, but if you were to

00:05:18,000 --> 00:05:21,000
kind of visualize, you can see that he's released that angle.

00:05:21,000 --> 00:05:25,000
He's creating pretty much all of his speed from his body rotation, from his shoulder

00:05:25,000 --> 00:05:31,000
pull, his tricep extension, but he's getting actually little speed from his wrist, which

00:05:31,000 --> 00:05:40,000
is actually pretty phenomenal given the fact that he can hit the ball about 400 yards.

00:05:40,000 --> 00:05:45,000
From a power path and face perspective, what typically is going to happen with the cast

00:05:45,000 --> 00:05:51,000
pattern is from a power perspective, the arms are going to go early.

00:05:51,000 --> 00:05:56,000
Now when the arms accelerate, that's going to cause some stabilization to occur in your ribcage,

00:05:56,000 --> 00:05:59,000
which is going to limit its ability to create speed.

00:05:59,000 --> 00:06:04,000
And it may even travel further down the chain and stabilize your lower body, so it tends

00:06:04,000 --> 00:06:09,000
to create slower body rotations, but as you saw where Jason Zubak, that's not always

00:06:09,000 --> 00:06:11,000
the case.

00:06:11,000 --> 00:06:17,000
From a path point of view, it gets the club head further away from you.

00:06:17,000 --> 00:06:23,000
So since it increases this distance, it creates a bigger circle and thus a shallower, typically

00:06:23,000 --> 00:06:26,000
angle of attack.

00:06:26,000 --> 00:06:33,000
So while not always, it's going to cause a path that's going to go slightly to the left,

00:06:33,000 --> 00:06:37,000
or slightly more to the left, which will require an adjustment from the body in order

00:06:37,000 --> 00:06:40,000
to not have the path go left.

00:06:40,000 --> 00:06:46,000
Lastly, because of what's happening with the right wrist, it will tend to open up the club

00:06:46,000 --> 00:06:53,000
face, as we'll see in the typical example somewhere around there.

00:06:57,000 --> 00:07:02,000
Now there are two typical complementary movements that you will see to the cast pattern.

00:07:02,000 --> 00:07:07,000
One is a forward lunge, or a shift of the upper body towards the target, and the second

00:07:07,000 --> 00:07:11,000
would be either a lift or a lack of drop.

00:07:11,000 --> 00:07:17,000
So if we look over here on the left, as this golfer makes transition, you will see the upper

00:07:17,000 --> 00:07:21,000
body in the head drift forward and then more or less stabilize there.

00:07:21,000 --> 00:07:23,000
There's not much backward movement.

00:07:23,000 --> 00:07:29,000
The backward movement would cause access to which would because that right arm is getting

00:07:29,000 --> 00:07:33,000
straight or sooner would typically cause the club to hit the ground.

00:07:33,000 --> 00:07:38,000
Also, you'll notice during transition, the height of this person's head stays almost

00:07:38,000 --> 00:07:39,000
the same.

00:07:39,000 --> 00:07:44,000
Now while this is frequently talked about as a good thing on TV, you will rarely see a

00:07:44,000 --> 00:07:49,000
good ball striker, especially with the driver execute that movement.

00:07:49,000 --> 00:07:52,000
Over here on the right, we have Ray McAurey, and you'll see that compared to where he

00:07:52,000 --> 00:07:58,000
started, he gets further behind the golf ball and actually backs up slightly during the

00:07:58,000 --> 00:08:04,000
release phase, but you'll clearly see an amount of significant amount of drop.

00:08:04,000 --> 00:08:11,000
The drop helps support the lower body creating speed, but if that right arm were straight

00:08:11,000 --> 00:08:16,000
at this point, you could see that that would lengthen or lower his hands, which would pretty

00:08:16,000 --> 00:08:18,000
much put the club head into the ground.

00:08:18,000 --> 00:08:26,000
So the combination of the lunge forward and the standing up helps to account for the increased

00:08:26,000 --> 00:08:31,000
distance between your hands and your chest that's common with this cast pattern.
