How To Throw A One Seam Sinker [with Sebastian Bentz]

In this video Sebastian Bentz shares how to throw a One Seam Sinker. He shows us the One Seam Sinker Grip, as well as how to throw it and the philosophy behind it. The One Seam Sinker works really well for Sebastian (as you’ll see in the video) and I think it can be a valuable asset to any aspiring pitcher as it has late downward movement and is on the safer end of the spectrum as far as pitches are concerned. Try out this One Seam Sinker next time you throw and let us know how well it works for you!

[@harpreetsmouron331]

This is one of the best and easier pitch to learn, that I've seen. I coach a 10yo team and showed it to a couple of kids who have hard time learning the change-up grip. One of them threw this one-seamer 3 times in a row to the best hitter in our league and fooled him every single time. THANKS!

I started throwing this pitch last year and had a lot of success with it. Very easy to throw, throw it just like your 4 seam. The key is definitely your grip. I had a lot of batters ask me, "what pitch was that?" Lots of jam shots

[@vmigop]

My 13 year old son has a low 3/4 arm slot, but we will give it a try. The sinker he throws now requires him to pronate as it’s released. Great video. Thanks!

[@leslieriell7920]

Fascinating: will definitely try the one seam sinker and change up

[@AnthonyRivera1]

I've been teaching to he is pitch to my kids for a few years now. I was throwing this for my slider but since I'm more 3/4 it moves more to the side. I try and have the kids think of it as a fastball that has late mocement. As most kids have different releases and grip strength it moves differently for each kid. Sometimes it is more of a vertical drop and other times it is more like a cutter. Good luck and try it out.

Hey thanks Coach Madden that was great. Going to have my son try that got my 10-year-old trying to hold it that way and I’ll get my 13-year-old it throws about 80 now to try it. He need something that’s our speed.

[@FerminStlCardinals]

Nice video Coach Madden. Though...there's a slight difference in his mechanics/arm slot (see side by side video), prior in releasing the ball. The difference starts when Sebastian has his leg lift, breaks (4.48) and starts cocking (4.53). With the 4-seam his hand is way much back than when he's throwing the 1-seam sinker. Also his release of the 1-seam sinker is higher/earlier than the 4-seam (4.55).....minor details that only a very very good hitter can pick-up. What I most liked was the difference on the vertical break compared to the 4-seam, also a good pitch to teach kids (age 12-15) to throw instead of the curve ball, less stress on the arm.

[@DjStalin100]

Great pitch and not harmful to arm. 👍

[@tristramcoffin926]

My son loves watching off-speed pitchers, and wants to add another elbow-safe pitch for spring. Would you list out a progression of pitches to learn? For reference, he’s a 8yo minor’s pitcher, with 45+ 4-seam FB and a circle change up. His consistent mechanics is because of you. THANK YOU!!

[@ltravail]

It seems these days that every aspiring pitcher who has tommy john surgery comes back stronger than before, almost bionic. Maybe you should consider tommy john for your 8 yo. By the time he gets to little league he should be unhittable, with that kind of pitching arsenal already.

[@franciscogutierrez3095]

I always wonder more about the release, and whether you rotate anything, fingers, wrist or arm, can you talk about the release? It took me a while to understand what creates movement even on fast pitches!

[@BG-ef3zg]

Hold it a little bit tighter and a bit farther into the palm. I used to call it my “main curve” as it dropped better than my curveball. I keep my fingers close together, and on the dominant side of the two seam grip. (For me, a lefty, the left seam) you don’t have to go all the way down on the horseshoe, stay in the middle. There should be no release or wrist action different than your 4 seam. Throw about 70-80% velocity of your 4 seam, and it’s a very successful pitch. I’ll subscribe to you, so try to make a video for what you think the grip is and dissect how you would throw it. I’ll comment and try to help you more.

[@hrivera463]

I always thought and threw the one seam as a cutter

[@sydzhen6493]

I think it just another form of forks ball/splitter as the theory behind them are both about lessening the spin rate and magnus force,so the ball can drop when approaching the zone,however, it’s still a cool pitch 👍

[@blakedameron133]

T ff7 7uuhyyy jujgh

[@scottl3794]

Is there more pressure applied to the index or middle finger to get more action?

[@user-do4gj2yb6y]

My 11 yo now throws it thank you

[@user-ht8ct7el4x]

Does the finger length affect the pitch?

[@frankpalancio8471]

There's different types of 4 seamers... he's talking about a 'wide' 4 seamer where you put your fingers across the widest part of the seams. When I throw a wide 4 seamer I get a lot of downward movement so I use that grip for my sinker. I use a 'narrow' 4 seamer for my straight pitch.

[@codybooth7189]

Is the grip opposite for righties

[@1REALJESUS]

Would this be a good pitch to teach 11-12 year olds since it's the same arm action as a fastball? I know 11-12 old shouldn't learn a curve and I wanted to throw something in besides a 4 seam and change-up so I was looking at this pitch

That’s nasty. The bottom falls out from under it at the end. He’s gonna have a lot of batters looking for holes in the bat on the way back to the dugout after they strike out. Love you stuff. Wish I would’ve had it 35 or so years ago. But I had Joe Donaldson helping me. He pitched in college and the minors... so, I had that going for me. Thanks again.

[@geesecougar2]

Can batters pick up the spin on this after a while?

[@wordragon]

The one seam release was actually higher and yet he had to chase the catch at the conclusion, which typifies a great sinker.

[@fredmertz2175]

I know the arm action and spin are different for the 1 seam versus a curve, but isn't the ball movement very similar to a 12-6 curve ball? Also higher velocity than curve.

[@YouGoPro]

Fred Mertz No the one seamer has backspin, a curveball has forward spin. If you are talking about the movement of the pitch then yes I guess you could say that. But I think a good Sinker beats a good curveball. But that’s just my opinion.

[@fredmertz2175]

In my mind, at least, I agree with you that a sinker should be better than a curve. My pitching coach wants the CB velocity no more than 15% below the velocity of the 4-seam FB. At my current age (15), it is hard to reach that consistently. Our 2-seam FB and sinker is only about 2-3 mph (low 70's) below the velocity of the 4-seam FB (mid-70's), so I expect the velocity of a 1-seam pitch to be close to the velocity of the 2-seam pitches, for us at least. And I have to pronate the 2-seam sinker to get much movement of the pitch (down and slight arm-side movement). So, the 1-seam pitch should be faster than my curve, about as fast as my 2-seam pitches, a bit easier on my arm and much more consistent than my curve. All, IMHO, of course.

[@cantripleplays]

@@fredmertz2175 have you tried it yet?

[@fredmertz2175]

@@cantripleplays Cantriple Plays - I didn’t play Showcase or Travel Ball in the last year. My HS coach only calls 4 seam, curve and change-up so I was not allowed to throw it in BP or game situations. I played Jr. Legion ball, but one of my HS coaches was the pitching coach so that ruined that opportunity.

From experience if you can’t throw this pitch correctly 100% of the time don’t even try it. As a hitter when pitchers could throw this correctly it was the hardest thing to hit, but if they messed up once, then it was just a BP fast ball

Sensation also broke his hands before he went forward, really well. He stayed back, got loaded on his backside, not drifting forward and walking away from his arm, which allows his arm to get up, so he’s on top of the ball and throwing down hill. I would have liked to see his 1 seam change up.
