Stephen Pryor Scouting Report 6.2.12 - Mechanics

=== Checkpoints ===

As y'know, aiki dynamics focus on the center of gravity, its acceleration and the organization of the head and limbs around that CG.  Still, all we have are screen captures here, so we have to start with a static description of the movement.

Here is the live video of the below pitch.  We'll restrict our description mostly to things that are NOT routine for ML pitchers, and remember that things are going to look quite different because of Pryor's bulk:

 ......................................................................

Pryor's overall pace - his time between pitches - is delightfully fast and confident.  His tempo, the speed at which he accelerates into his motion, is delightfully smooth and slow.  Moe, have a gander at this and tell me if you don't grok a PGA-pro type of takeway?  Smooth, confident, and unhurried?

Just a great, great intersection of pace and tempo.

In the rock back, Pryor connects his shoulders with the center fielder, Japanese-style.  He sticks his foot out, away from his body, as if he were a high wire walker using a pole to balance himself.  This last bit is kind of weird and you wonder whether it will mess up his ability to hold runners.  I dunno.

Pryor has an absolutely instinctive desire to rock his shoulders backward to second base, one that he doesn't think about.  He just loves to get onto his back hip, to raise the hammer before it falls.  Gotta love it.

 ......................................................................

In the second phase of his gather, Pryor draws a Figure 4 with his front foot.  Probably no aiki sensei would go for this "affectation," the pretzel motion of the lead foot, but to me it gives a type of Japanese "pause at the top" as everything organizes neatly down the centerline.

.

 ......................................................................

Now Pryor's lead foot reaches out for the plate as if a blind man were using his cane to find the curb.  The hands separate in such a way as to keep the baseball connected to Pryor's CG, his "one point."  He sinks onto that colossal gluteus maximus and he needs little shoulder turn, which is one reason that his eyes and intentionality are unusually oriented down the centerline throughout.

Dr. Mike Marshall and his "driveline" paradigm would be pleased.  An aiki sensei would be also.

.

 ......................................................................

Pryor starts to splay the limbs in four directions, keeping a high front side (glove high and front shoulder raised).  This will allow an arc'ing of the shoulders, creating a downhill angle and, in Pryro's case, a magnificently on-top-of-the-ball release. 

The organization around his hara, his CG, is unpretentious and to the point.  An aiki shihan would speak of great sincerity.  Yes, Pryor sincerely wants to remove the batter's will to compete with him.

.

 ......................................................................

This, gentlemen, is called getting on top of the ball.

..............

Dr. D's big complaint, though...  You can't see it here, but Pryor rips his shoulders around with his head.  Here's the video again.

It's one thing to have a max-effort delivery; that's the way that Pryor should pitch, throwing the ball absolutely as hard as he is capable.  Pryor isn't going to be a guy who hits razor-fine spots within the zone; it's good enough for him to hit ANY part of the zone.  Troy Percival pitched that way forever.

But Pryor needs to remove the shrillness from his head yank.  Until he does his most realistic goal is going to be simply to throw strikes.  Ever play Pop-a-Shot basketball in the arcade?  If your eyes are moving like this, it's like trying to shoot at a backboard that is bouncing around.  While you shoot.

You'll notice, too, that Pryor's head is a bit left of his lead foot at release.  This is supposed to be a big no-no.  That's a golden principle, head balanced inside the feet as you let the ball go.

..........

Don't get me wrong.  Felix yanked his head his first two years; Lee Trevino used a grotesque motion his entire PGA career.  The ball wasn't going anyplace on Trevino, and the strike zone is always in the same place for Pryor.   Probably half of the max-effort relievers in MLB have less-than-perfect head movement.  It's a crazy thing they're doing, throwing 97 MPH.

And Pryor was thrown into a terrifying situation in his debut game.  If I had my way, I'd like to see the head smooth out a little, is all.  Stay down the centerline better.  Felix mastered this over time.

.

 ......................................................................

The torso is fully parallel to the ground and the right arm clears loosely, not banging against his chest - the decel actually reminds of Randy Johnson, mirror image.  The back leg, a favorite Bill James "tell" for a tiring pitcher, is enthusiastic and comfortable.

Pryor dissipates his energy through his decleration better than most guys half his weight.  He's very graceful for a guy who weighs upwards of 500 lbs.  Impressive caboose, too.

This is the dissipation, anyway, of a man who's going to pitch for 15 years.

.

=== Dr's Diagnosis ===

Pryor has thrown strikes everywhere he's been; apparently he hasn't been hitting spots with Jamie Moyer surgical precision, but that's fine.  It didn't do you any good that Troy Percival was wild inside the strike zone.

Pryor's motion is "sincere" and without pretention; he gets his belly button into the action and he uses the C.C. Sabathia-sized core greatly to his advantage.  He's not looking at great command inside the zone with such a max effort, but then again you're not talking about Dan Quisenberry here.  You're talking about 99 MPH, strike one.

Would like to see him continue to keep the eyes moving toward the catcher better.  That said, two thumbs way up.  There will be a rookie Pyror and a 4th-year Pryor, and the rookie Pryor looks ready to roll.

.

BABVA,

Dr D

It's a rock and roll motion, Doc. And smooth on the rock.

He rocks back onto that ack leg, gets into that straight line position, and then just unrolls to the plate: Leg, hips/shoulder, arm.

I'm glad you mentioned the glutes, too.

This is smooth-easy/powerful-low stress (as much as 100 MPH can be).

Sam Snead, if he threw a ball. Or Freddy Couples.

Those kind of motions last forever.

SpectatorNow Victor Sanchez on the DL too!57 min 40 sec ago
SABR MattI think it should be Iwakuma. He can throw 4-5 innings and gut it out...I'd rather get him back in the fold tha start someone else's service clock running or rush a guy who's clearly not ready.1 hour 22 min ago
Tacoma RainAt least Fernandez went 6 innings on his last start, and he is on the 40 man. Maurer only went two innings in his last game, although he went 3 in the game before. so???1 hour 53 min ago
Gordon GrossI'd rather see Maurer fill a spot if we need it, but he's still working outta the pen after HIS Spring Training health bobble. Hoping for some good news on our very-full injury report soon.2 hours 46 min ago
Gordon GrossFor anybody wanting Victor Sanchez to get a surprise promotion as the next stud arm up: Victor is the youngest player in the Southern League by over a year - to Ketel Marte, fellow Mariners prospect - and by TWO YEARS to the 3rd youngest player. Steve Landazuri, Mariners farm arm, is the 9th youngest player in that league and is 3 years older than Sanchez. They're likely to let him season a bit, y'know? If he's GREAT, maybe he can Bumgarner his way up at the end of the season. Not now.2 hours 50 min ago
Gordon GrossTom Wilhelmsen's return the the rotation is gonna happen shortly if we can't straighten out this pitcher nonsense. And welcome back to Nick Franklin. IMO it means more starts for Saunders (they're both better as lefties) and we have Romero for righties (or Willie for either infield or outfield duty). Nick is insurance on our insurance, but I still hope he gets into games quickly. He's blazing hot right now - don't cool his heels on a bench for a week, please.4 hours 7 min ago
moethedogFrom MLB-TR: Morales Rejected $30MM Extension Last Summer Well, if so, I will begin to question his sanity or that of Boras. Wo with Franklin coming up the interesting question is where in the heck do you play him? Do you throw him into RF and let him sink or swim, basically with a couple of innings of lifetime experience? DH him and play Hart in RF? 3B until Seager finds his bat? SS? IDK, but I do know that we need a leadoff hitter to get on and some consistent rocking from DH and 1B (although both had singles last night. 2, in fact for Hart).4 hours 43 min ago
MtGrizzlyDivish: "Nick Franklin was pulled from tonight's game in Tacoma in the eighth inning. Most of you know this isn't normal. And Franklin wasn't hurt. The exit was to prevent him from being hurt before the Mariners likely add him to the 25-man roster tomorrow. Multiple sources have confirmed that Franklin is being called up. Expect Franklin to be join the team in Arlington on Wednesday. The corresponding move would assumed to be placing Logan Morrison on the 15-day disabled list. Morrison had his injured hamstring heavily bandaged today when he went out to batting practice.7 hours 10 min ago
Dag GummitJust came across BP from the beginning of the season that projects Zunino as the third-best framer in all of MLB: http://www.baseballprospectus.com/article.php?articleid=231768 hours 29 min ago
Tacoma RainSo A Fernandez or Caraway next???12 hours 23 min ago
OBFTrade back for Noesi... :)13 hours 57 min ago
MtGrizzlyWho is in line to take Beavan's turn? Ruffin?14 hours 34 min ago
OBFSomeone Quarantine Felix NOW!!!!!14 hours 39 min ago
OBFIt's and epidemic... smh :(14 hours 39 min ago
MtGrizzly@RyanDivish: Beavan said he knew his velocity was down and tried to make pitches as best he could.14 hours 43 min ago
MtGrizzly@shannondrayer: Beavan came out of game w/shoulder stiffness. Thought it would loosen up in game but didn't. Concerned w/velocity and lack of life on ball14 hours 44 min ago
OBFThis Offense is feast of famine... M's Runs this year: 10, 8, 8, 2, 3, 3, 5, 0, 6, 1, 0, 7, 0 Six games with lots of runs (5+), Five games with few runs (0-2), only 2 games with an average/medium amount of runs (3 or 4)... and interestingly it doesn't seem to actually have that much to do with starting pitcher handedness...14 hours 50 min ago
OBFOptimist Outlook: “I am sure Taijuan just slept awkwardly last night and he woke up a bit stiff, and all will be fine tomorrow” :) Pessimist Perspective: “Well Dr. Andrews… prep the table” :(14 hours 55 min ago
rick82Lol. It was certainly....disturbing, Mojician. I think Doc is trying to get some women into the site.16 hours 12 min ago
