I might ruffle some feathers with this, but I’m just going to go ahead and say it. I believe that most young pitchers should learn to throw a good curveball.

This may be surprising to some, so let me explain. I believe the curveball has gotten a bad rap. Over the years, the curveball has been blamed for countless youth pitching injuries, surrounded by the fear that throwing it would doom a young pitcher to a trip to orthopedist or even the operating table.

But here’s the thing…

There’s mounting evidence supporting what some of us have suspected all along. The curveball isn’t the problem… too much competitive pitching is the problem. Kids pitching year-round for three different travel teams is the problem. Our youth sports culture is the problem…

But that’s a whole other can of worms, and not what I mean to tackle with this article. Instead, I just want to shed some light on what the research says and why I believe most pitchers should learn to throw a good curveball early in their development.

Now, before I go on, let me just clarify what I’m talking about. I’m not talking about 8 and 9 year olds throwing nasty hooks. When asked when a young pitcher should start throwing a curveball, here’s my pat answer:

“When he’s ready.”

And that vague sort of guideline isn’t meant to be annoying – it’s just the truth.

Commanding good old # 1 should be the first priority.

Pitchers should develop good mechanics and demonstrate an ability to command their fastball before wasting time working on secondary pitches. That doesn’t mean you need to have pinpoint accuracy – I’m not saying:

“Once you can hit the outside corner with your fastball 50 times in a row, then you can start working on your off-speed pitches.”

That’s just unrealistic. If that was the approach guys took, nobody would ever develop a good curveball, changeup or anything beyond a fastball, for that matter. But you should be able to work the ball to each side of the plate fairly consistently. And, perhaps more importantly, you should have a good enough feel for you fastball and your mechanics to be able to make an adjustment within one or two pitches if you miss your location.

In most cases, this means waiting until a pitcher is 12 or 13 before introducing the curveball, but it could be sooner, could be later.

Let me also clarify, I’m specifically talking about “introducing” the right way to throw a curveball. We’re not talking about throwing it 30 times a game or anything even approaching that. Overuse can take a lot of forms – throw too many curveballs on the mound and you’re more likely to fatigue your arm, and as Dr. Andrews with ASMI has stated repeatedly, pitching with fatigue is the number one risk factor for youth pitching injuries.

Introducing the curveball means showing the young pitcher the right way to throw a curveball so that he can work on it and develop it into a good pitch as he gets older.

It may seem like a contradiction, but I still firmly believe that for young pitchers the vast majority of your pitches in a game should be fastballs.

Okay, so now that we’re clear on what I’m talking about with young pitchers learning to throw a curveball, let’s look at what the research says. In recent years, numerous studies have come out showing that the curveball may not actually be the big threat to young arms that many have feared. In fact, the studies were not able to find any link between throwing curveballs and an increase in injuries, and actually indicate that curveballs place less stress on the elbow than fastballs.

The studies themselves are worth diving into and dissecting, but again, that’s a bigger topic and beyond the scope of this article (this post is getting long enough as it is). For a list of studies and some of the best articles I’ve found on the topic, see the notes at the end of this post.

To be fair, the studies are far from complete and shouldn’t be seen as an “all clear” that curveballs are somehow a “safe pitch” for young pitchers.

In a New York Times article, Dr. Andrews himself expresses concerns with the studies:

“It may do more harm than good — quote me on that,” Andrews said during an interview in his Birmingham clinic. He fears that parents and coaches may interpret the findings improperly, as a license to teach kids to throw too many curves or begin when they are too young. “There are still some unknown questions.” – read the full article here.

When you’re going through rapid physical development and growth spurts, the growth plates are most vulnerable to injury. For this reason, Dr. Andrews still recommends pitchers waiting until they start shaving to begin throwing curveballs. That said, while curveballs may place a different sort of stress on the elbow (due to the skeletal structure of the arm and the different wrist and hand position), the growth plates issue is something to keep in mind for all young pitchers whether they’re throwing curveballs, fastballs or any pitch.

So it may still be best to wait until you’re physically more mature to start throwing curveballs regularly in games. But learning to throw a curveball the right way and throwing it repeatedly at full intensity in games are two very different things.

Okay, so after that very long preamble, I’ve hopefully clarified my stance. I’m not, not, not saying kids should all go out and start throwing a million curveballs in games. But in most cases, they can benefit from learning to throw it early on. So without any further rambling from me, here you go…

4 Reasons Young Pitchers Should Learn to Throw a Curveball:

 

1. They’re going to throw it anyway – why not teach them the right way?

Whether you teach them or not, kids are going to mess around with different grips to try to get the ball to move. Most of the time, kids think throwing a curveball involves aggressive twisting, turning or snapping the wrist. There’s even a conventional coaching cue that tells kids to “turn the doorknob” – this is a pretty awful teach.

When kids throw a curveball this way, aggressively turning or twisting, they aren’t going to get the best break on the ball, and they likely put their arms at greater risk of injury than had they learned to throw it properly. To throw a true big league curveball, you want your hand and wrist on the side of the ball (supinated) at ball release, but there should be no active twisting going on.

 

2. The older you get the tougher it is to learn.

Will waiting until you’re 18 reduce the risk of getting hurt throwing curveballs when you’re younger? Sure, but as the research shows, the greatest risk for youth pitchers isn’t throwing curveballs… it’s too much competitive pitching – period. Pitching is an inherently unnatural act – the human elbow was simply not designed to handle the stress of throwing a baseball at high velocity. The best way to stay injury free would be to just sit on the couch and never pick up a ball.

If you decide you’re okay with the risk/reward of pitching, it makes sense to learn something that can make you a better pitcher. On top of that, the advantage of learning young is that you’re relatively malleable. You’re not fighting years and years of old muscle memory and ingrained movement patterns. Learning to throw a good curveball takes time and lots of practice. Wait too long, and you may never develop a good one.

3. It may actually place less stress on your elbow than the fastball.

More studies need to be done, and there are still the growth plate concerns, but there’s one thing the research shows pretty clearly – the forces on the elbow that lead to UCL tears (think Tommy John surgery) are greatest with the fastball. In my opinion, this is partly because the curveball is generally not a max-effort pitch. You just don’t need to throw it with the same force you do your fastball for it to be effective.

On a personal note, I battled UCL issues in my career (mainly due to poor mechanics, overuse and lack of preparation when I was young), but while I know what elbow pain feels like when throwing a fastball, I never once threw a curveball that hurt my elbow.

4. A good curveball can lower your pitch count when you’re older.

A good 12-6 curve (or 1-7, or 2-8, whatever it is based on your arm slot) can be a great weapon in your pitching arsenal. Being able to command it effectively (in the zone and out) can really keep hitters guessing and give you a put-away pitch, leading to more strikeouts and shorter innings.

Summing up: So that’s my stance on young pitchers learning to throw a curveball. Again, I still think job #1 is commanding the fastball. But once a pitcher is ready, learning to throw it the right way when they’re young can give them a nasty curveball they can use in games when they’re older.

[h4]Get bigger with your stride to throw high…[/h4]

We all know the importance of commanding your fastball down in the zone, and many (myself included) will recommend throwing roughly 80% of your pitches down there. For more on this, read this article: The Importance of Commanding Your Fastball. But something worth pointing out is that the philosophy behind this line of thinking is based on what works at the big league level… Kyle Boddy actually wrote a nice piece on this topic a while back: Locating Up in the Zone – Better for Amateur/Recreational Pitchers.

As most youth pitchers could tell you, there’s a pretty big difference between the fielding ability of guys at the big league level and the amateur level. And it can get frustrating making good pitches and getting ground balls only to watch them turn into fielding errors and seeing-eye hits.

On a personal note, much of my success at the high school level came from my ability to elevate my fastball. I’d gotten used to playing with “less than stellar” defense behind me, and as a result I developed into more of a strikeout/flyball pitcher.

In college I had to get used to facing batters who could get to that high fastball. And I eventually got comfortable with the idea that I actually had fielders behind me who could make the plays. But even though I learned the importance of commanding the ball down in the zone, I never lost sight of the value of elevating my fastball, and it continued to be a great weapon for me.
[h5]So what about when you want throw your fastball UP in the zone?[/h5]

Every now and then you’ve gotta change the hitters eye level – get them off that low fastball or blow it by ’em to finish them off. And as mentioned above, sometimes commanding your fastball up in the zone can work better for you than keeping it down all the time. But often when pitchers spend all their time working to keep the ball down, when you ask them to throw one high, they struggle. They either miss way too high or don’t get it high enough (the power of muscle memory).

Most pitcher’s have been there at one time or another… You get ahead in the count, 0-2. Nice! Then you to try to throw a fastball up in the zone for effect, only to leave it belt high. The dreaded 0-2 meatball! Never a good thing…

To make that high fastball work, you have to elevate it! But how do you learn to do that?
[h5]You’re better off focusing on your lower half than your release point:[/h5]

When young pitchers throw one high by mistake they’ll often say things like, “Oh, I let go of that one early.” And they’re right… but what’s more important is WHY they let go of it early. Most of the time, it comes back to what they did with their lower half.

The throwing motion (arm acceleration from max external rotation to ball release) is one of the fastest human movements in all of sports. The difference in release point between a high fastball and low fastball is imperceptible to the naked eye.

So if you try to elevate your fastball by thinking “I’ll just let go of the ball early,” what are the odds that you’ll actually get that timing right? Not good… More likely, you’ll end up slowing your arm down or throwing it 10 feet over the catcher’s head.

[h5]How your Lower Half affects your Upper Half in your pitching delivery:[/h5]

Instead of over-thinking it or trying to “aim the ball” with your throwing arm, try getting aggressive with your stride length.

But isn’t an aggressive, powerful stride something you want on every pitch?

Yes, but there’s a balance… the stride is about generating momentum and accelerating down the mound. But then you want to brace up and get over your front leg when you throw. You’ll often hear pitchers and coaches talk about the importance of throwing downhill. They’re basically talking about getting over the front leg.

Felix-Hernandez-Side-Release-2

 

Take a look at Felix Hernandez getting over his front leg

See, when you get really aggressive with your stride length and effectively over-stride, you don’t get over your front leg as well. The result? You usually miss high… Make sense?

It’s the same way with shortening your stride. Shortening up a little can be a quick fix to help you get on top of the ball and get it down in the zone (see how this worked for Cubs minor league pitcher, Nick Struck: Why a Longer Stride Isn’t Always the Answer).

[h5]How to use this trick to help you on the mound:[/h5]

Try it out in the bullpen first – get the FEEL for elevating your fastball. As you prepare to make your pitch, decide you’re going to really crank it up with your stride length. Then load up and let it go. Often times, that high fastball will just happen without even thinking about it.

Now I generally don’t like relying on mechanical cues in game situations. During competition you’ve got enough going on without having to worry about mechanics. That’s why this is something to work on in your practice and bullpen sessions.

To sum up: Getting aggressive with your stride can be quick and easy way to get that fastball up in the zone. But I am NOT suggesting you actively over-stride every time you want to elevate your fastball! It’s all about getting the feel for throwing high. Once you get that feel and work on it in practice, the key is to remember what that feels like. Then in the game, forget about mechanics so you can focus on what really matters – making good pitches!

Did you see this article? Little League Mechanics vs. Major League Mechanics

In it I talked about one of the big mechanical flaws you frequently see with young pitchers: Opening the hips early. Another way to think about this is “not Loading the Hips properly” in the stride.

I got a few questions from guys asking how they could address this mechanical with their pitchers. So I put together a short video (with voice-over) to give you a better idea of what loading the hips looks like, along with one of the drills I use for teaching this component.

Loading the Hips is one of my 4 Power Pitching Components:
1. Linear Momentum (early momentum)
2. Loading the Hips
3. Hip to Shoulder Separation (torque)
4. Stabilizing the Front Side (front knee, glove arm)
[hr] [h4]Some videos to help address this mechanical flaw:[/h4] 1. Opening the hips early: Young pitchers often swing the front leg out, opening their front foot early, effectively unloading their hips. See video below (no audio):

2. Loading the hips with Fernando Rodney: Watching Fernando Rodney shows you how you can load your hips without a big leg lift (or any leg lift). Now most pitchers will struggle with a “no leg lift” delivery, but the video below show you how staying loaded and closed with the hips is more important than a big leg lift (he throws 100 MPH).

3. One of my favorite drills to help develop the feel for loading the hips:
This one sets you up in that same loaded-up hip position you see with Rodney in the video above. How high you lift your leg is up to you.
