Pitching Mechanics: David Price
Let's not waste any time. Rays fans have already waited too long for this post. You'll have to click through for the pretty GIFs, though.
David Price is one mean fireballin' lefty. I could post his stats and his PITCHf/x makeup here, but honestly, other sites have done that to death and it's not worth repeating the work for no particular reason. You all know that he dominated in college and cruised through the minors, so let's get down to the nitty gritty.
Price worked in the 90's during his whole tenure, hitting 97 mph occasionally. His delivery is fluid and scouts love his stuff and his loose arm action. Most people aren't worried about his arm trouble before, and neither am I. The videos below will indicate why.

Boy, that's pretty, isn't it?
Arm Action / Tempo
Here's what we can take from David Price's arm action:
- Tempo: Price is 20-21 frames from maximal leg lift into footplant. That's a bit slow, but he is a big boy. I give him an Average grade.
- He embodies the "sit down" motion that Nyman followers love. For the record, so do I. You find this type of mechanic in Roy Oswalt and Tim Lincecum as well. It's not "Drop and Drive" like Tom Seaver, but more like "Get it and Go" (credit: Carlos Gomez). It helps to pick up tempo and maintain an aggressive delivery.
- Price does have a bit of "wasted motion" as Will Carroll would like to say, but it's nothing major. Clayton Kershaw has the same "problem." Nothing to worry about.
- His arm action into the high-cocked position is beautiful: The hands break at the belt, they go down, back, and up in a pendulum swing with no signs of early pronation. The following images prove that:

Price with the ball facing 1b and not CF - No Early Pronation!
- At the point when the shoulders begin to turn, David Price's arm is nearly vertical. This is excellent and shows no signs of timing flaws. (You can see this in the two frames I paused for a second each.)
- Additionally, note how Price keeps the elbow below the shoulder. This is another great sign for future health.
- I grade his Arm Action as Excellent.
Ball Release / Followthrough
- Does this followthrough remind you of anyone I like? It should:

- Price has a more aggressive followthrough and finish, simply because his mechanics are more aggressive and because he throws significantly harder than Justin Duchscherer.
- Price firms up the front side very well and uniformly decelerates his arm while pointing the pitching arm shoulder at the target. He brings around his leg, not leaving it on the mound, completing the deceleration phase.
- I grade his ball release / followthrough phase as Excellent.
There is a ton to like about David Price. The only thing I'd like to see is a bit quicker motion to the plate, but it's hardly worth fixing if it causes him even the most minor of troubles with velocity and/or location.
Rays' fans - you've got a good one on your hands. Scouts weren't wrong when they said he could get out major league hitters right now.

Thanks for this. It's awesome.
I pretty much salivate over our rotation next year.
Kazmir
Shields
Price
Garza
Sonny/Jackson/Niemann… awesome!

Yep.
Don’t forget about Wade Davis, either.

What about Mitch Talbot, got any quick thoughts on him?
Sure has a nice K/BB ratio in AAA ( >4 )

Davis in my opinion is about a half a season away. He is looking a lot sharper alot more polished.
I look forward to seeing what Davis looks like in Spring training. I also fully believe that Jake McGee will be a dominate set-up guy with his brutal fastball.

Well McGee is done for next year regardless obviously and his slider is *knockout* too
But Kazmir/Shields, Garza, Price, Sonnanstine/Jackson is a sick rotation just to start with. They can deal one of those guys or Davis/Hellickson in the pipeline for outfield/bullpen help or maybe a SS who can hit? (they are 10th in the AL in runs scored)
If I was the Rays I’d target Brandon Wood. He can find enough playing time at short between Bartlett as well as giving Longoria some breathers at 3B and provides some high upside hitting that they really do need. I know you can never have enough pitching but they have 8 legit options for the rotation next year, at some point you have to say “if 5 guys get hurt we’re screwed anyway”.

Seems like several teams are looking at B. Wood
The price on him could skyrocket if everyone really needs him.
Space.
It's a problem we face.
So we never go anywhere.
We just stay in one place.

Thanks Kyle
Your effort is well appreciated and it is nice to be reaffirmed by someone as thorough as yourself.
Be who you are and say what you feel, because those who mind don't matter, and those who matter don't mind.

Excellent analysis!
As usual, great job, Kyle! I’m now doubly glad that I was able to pull an autographed baseball card of this guy after pulling down three packs of 2008 Bowman at the local drug store, heh.

Price is Nasty
I just finished up a post on his stuff. I’d like to hear more from others on that slider/slutter/cutter. Whatever it is, it’s vicious, and he’s missing a lot of bats. Even more impressive is his fastball, which gave the Yankees and Twins a lot of trouble. Check it out, and please pick apart the pitch ID.

Here is a real biomechanical evaluation of this pitcher
He uses the prototypical ‘traditional’ baseball pitching motion.
That means that he starts by turning his pitching foot to parallel
with the pitching rubber and raising both arms high over his head.
Then, as he starts to lower his glove and pitching arms, he lifts
his glove leg very high off the ground. He nearly touches his chest with
his glove knee.
Interestingly, he starts to lower his glove leg while his glove and
pitching arms are still chest high. Usually, ‘traditional’ baseball
pitchers wait until their glove and pitching arms are closer to waist
high.
This early lowering of his glove leg means that he starts to move
the center of mass of his body forward earlier with regard to his
backward movement of his pitching arm.
He reverse rotates his hips very far beyond second base. I would
estimate that his hips point at least sixty degrees beyond second base.
However, he reverse rotates his shoulders only about thirty degrees
beyond second base.
While he takes the baseball out of his glove with his pitching hand
on top of the baseball, he does not raise his pitching elbow to shoulder
height before his pitching hand reaches driveline height. This means
that he does not have ‘Reverse Pitching Forearm Bounce.’ Therefore, I
would say that he is not in danger of rupturing his Ulnar Collateral
Ligament.
While he reverse rotates his pitching upper arm farther than he
reverse rotates his shoulders, which means that he takes his pitching
elbow behind his acromial line, he does not generate much force.
Therefore, I do not believe that he will suffer serious front of the
pitching shoulder problems.
He also does not ‘grab,’ which means that he does not bend his
pitching elbow tight to his pitching shoulder before he starts to move
his pitching elbow forward. Therefore, he does not have a ‘loop.’
However, he does take his pitching arm at least two and one-half
feet laterally behind his body toward third base. This means that, to
return his pitching arm to the pitching arm side of his body, he has to
apply sideways force to the pitching arm side of his body.
Therefore, he does have a serious problem with ‘Pitching Forearm
Flyout.’ As a result, the horizontal centripetal force that he generates
toward the pitching arm side of his body slingshots his pitching arm
away from the pitching arm side of his body.
This means that, to prevent the olecranon process of his pitching
elbow from slamming into its fossa, he has to powerfully contract his
Brachialis muscle. Therefore, he will enlarge the coronoid process of
his Ulna bone and lose flexion range of motion in his pitching elbow.
To determine whether he supinates the release of his breaking
pitches, I would need to see high-speed film of his releases.
Nevertheless, because ‘traditional’ baseball pitchers typically release
their breaking pitches over top of their index finger with their
pitching thumb turned upward, I believe that he does supinate the
releases of his breaking pitches.
Therefore, he will occasionally slam the olecranon process of his
pitching elbow into its fossa. As a result, he will lose extension range
of motion in his pitching elbow.
The extreme horizontal centripetal force of his ‘Pitching Forearm
Flyout’ requires that he pulls his pitching arm forward. Therefore, he
will suffer injuries to the front of his pitching shoulder. Also,
because, to dissipate this force, his pitching arm moves across the
front of his body and downward, he will unnecessarily stress the back of
his pitching shoulder and posterior Labrum. Fortunately, he pulls his
pitching arm more downwardly than across the front of his body, which
decreases the lateral stress.
With regard to his body action:
01. When he drives his body forward off the pitching rubber, he puts
extreme stress on the medial and lateral sides of his pitching knee.
Therefore, he will lengthen the Medial Collateral Ligament and damage
the lateral surface of his glove knee. As some point, I expect that he
will tear his Lateral Meniscus.
02. Because he reverse rotates his hips so far beyond second base, he
places severe stress on the medial and lateral aspects of his pitching
hip. While this injury usually takes years to manifest, with the
intensity of his hip rotation, I expect that he will injure his pitching
hip.
03. Lastly, Mr. Price strides too far and strides closed. Therefore, he
places severe stress on the L5-S1 inter-vertebral disk. While this
injury also usually takes years to manifest, with the intensity of his
forward bend, I expect that he will injure his lower back.
