Free Interval Throwing Program / Return to Throwing Program for Pitchers

Most interval throwing programs out there are very conservative and don’t have enough intensity in them at the end periods to adequately build up to throwing flat grounds and bullpens with all your pitches. Furthermore, there’s not enough ballistic and plyometric activity to really build range of motion and arm strength. I reviewed a bunch of these from my pro athletes and told them all I’d write them an interval throwing program, and decided that I might as well make it openly available to everyone, since I’m sure others are suffering from the same problems!

You’ll need our free Ballistic Training eBook that has all the videos and descriptions of the exercises, so go ahead and get that first:

Ballistic Training Program – FREE eBook

(furthermore, that eBook is something you can use AFTER the interval throwing program, if you so desire)

Then, after that, go ahead and download the free interval throwing program on Google […]

Weighted Baseballs vs. PlyoCare Balls – What’s the Difference?

We get this question a lot – what the heck is the difference between PlyoCare Balls and Elite Weighted Baseballs? Is there a difference? In fact, they are pretty substantially different.
PlyoCare Balls

The soft-covered PlyoCare balls are primarily meant for submaximal throwing and for constraint training, as well as general arm care. They’re not meant for throwing as hard as possible with zero mechanical intent to change; the point of PlyoCare balls is to provide a larger tactile feel in the hand that removes the connection to a baseball, further distancing the athlete from the idea that he has a baseball in his hand. Additionally, the large variation in weight between the balls creates greater changes in movement in the constraint drills (Pivot Pickoffs, Reverse Throws, Walking Windups, etc) as well, while the weighted baseballs have a much smaller weight distribution.

Here’s a short video of a comparison of two big leaguers using PlyoCare […]

Lower Half Pitching Mechanics: Data-Driven Analysis

The role of the lower half when it comes to the pitching delivery is open to interpretation by many coaches out there, which often serves to confuse the individual athlete. We’ve recently started a long-range analytical project using force plates, EMG sensors, and high-speed video to delve deep into what the lower half is really doing during a high-velocity throw. If you don’t follow me on Twitter (@drivelinebases), then you missed out on a few of our recent findings and data dumps.

Here’s some interesting information from our sports science lab on the lower half:

EMG Data + Synchronized Video

While this isn’t conclusive, it shows that the trailing leg hamstring and glutes are actually most involved during deceleration and not force production. When you consider that the hamstring flexes the knee, this makes a lot of sense, and that the rear glute extends the […]

Is Forearm Pronation the Key to Avoiding Tommy John Surgery?

If you spend enough time in the world of baseball pitching, you will probably hear from someone that actively pronating the forearm is imperative to protecting the pitching elbow. A reason often given is that pronating the forearm engages the pronator teres muscle.

The powerful pronator teres is a forearm muscle that attaches on the inside of the elbow (the medial side) near the ulnar collateral ligament (UCL). Its primary job is to pronate the forearm. When it is active, it generates a force that likely protects the UCL and therefore likely reduces the risk of Tommy John surgery.

Thus, some believe that if a pitcher actively pronates the forearm at just the right time, he or she will optimally engage pronator teres to protect the UCL. This is misleading.

The idea that one must pronate the forearm to utilize pronator teres is not actually true.

Yes, in general, it is true that one […]

Why You Weren’t Drafted or Recruited

On Twitter yesterday, I said:

With the 2015 MLB Rule 4 draft over and in the books, I’ve heard from a variety of people saying they are better than people that were drafted and how it’s not fair, how hard it is to get quality exposure, etc. First of all, I’d like to dispel the last one really quickly – and there’s a feature article coming eventually, but not now – an athlete at our facility named Christian Meister was drafted in the 29th round by the Cleveland Indians and was offered a contract + bonus. reporter August Fagerstrom wrote about it if you are so inclined to check it out, but like I said, the full story will be coming down the pipe eventually.

The takeaway from Christian’s story is that he didn’t even play baseball in 2015. That’s right, he just trained at Driveline Baseball, and when he was hitting 92-95 off an indoor […]

Can Imaginary Exercise Make a Pitcher Better?

I won’t bury the lead. The answer is yes, it is highly likely that imaginary exercise can make a pitcher better.

In the early 90s, several researchers set out to test the efficacy of pure imaginary exercise on the strength of a finger . (The finger was chosen because it has small muscles that are easy to test and isolate.)  The researchers had three groups of subjects: group 1 performed actual finger exercises, group 2 performed no finger exercises, and group 3 simply imagined the finger exercises performed by group 1.

After 4 weeks, the results were pretty incredible.

As expected, the subjects in the first group (the subjects that completed the actual exercises) increased the strength of the exercised finger by 30% on average. Also as expected, the subjects in the second group did not substantially increase the strength of the finger.

Now here’s the incredible part… the subjects in the third group, […]

Explaining the Elbow Spiral in the Pitching Delivery

Hayden Grove conducted a great interview with Trevor Bauer of the Cleveland Indians discussing pitching mechanics at a very in-depth level. I have to give Hayden some props; most beat writers wouldn’t dare to try to get into this kind of depth with a pitcher, and indeed most just shrug Trevor off. Hayden followed up the next day and tried to get into deeper detail, and as a result, ended up with a great interview that, while he may not fully understand, was definitely a net benefit for pitchers everywhere.

Trevor and I started working together in 2013 after his not-so-great year in AAA for Columbus, and that’s when we primarily discussed the concepts of Linear Distraction and Torso Stacking, the latter of which is also a Texas Baseball Ranch cue. Linear Distraction is simply a better and more complete understanding of how the torso stacks behind the midline at stride foot contact; by throwing the hips […]

Why Sir Isaac Newton is Still the Foremost Expert in Pitching Biomechanics

This post was written by Dr. James Buffi.

Most people have heard of Sir Isaac Newton and his famous laws of motion. Most have not heard that he was an expert in modern pitching biomechanics.

So let’s talk about how Newton’s most famous law relates to pitching.

Newton’s most famous law of motion is probably F = ma. Force equals mass times acceleration.

This law dictates that the acceleration of an object, like a baseball, is dependent on both its mass and the outside forces acting on it. F = ma is the foundation of all mechanical analyses and therefore it’s important for pitchers (and really all athletes) to understand what it means.

In F = ma, the “m” stands for mass. Mass is a measure of how much matter, or “stuff,” an object contains. An object can be really large in volume but have very little mass, and vice versa.

A blimp is huge, but […]

Why Overuse May Not Be Baseball’s Problem

This post was written by Dr. James Buffi.

‘Overuse’ is being blamed for the eruption of Tommy John surgeries among baseball pitchers. Consequently, people in baseball have become hyper-focused on preventing overuse of the pitching arm. This has led to pitch counts, inning limits, and training guidelines that are more restrictive than ever before.

And yet ulnar collateral ligament (UCL) injuries continue to mount.

Usage restrictions are not helping because no one really knows where the line is between ‘acceptable use’ and ‘overuse.’ And the line will be very different for every pitcher. It will depend on many physiological factors, including physical fitness, that are constantly adapting and unique to each individual. A recent study attempted to find a general relationship between previous innings pitched and future injury in professional pitchers , but no significant correlations were found. Despite the lack of justification, organizations continue to excessively restrict throwing because they don’t know […]

Rehabilitating Tommy John Surgeries – Non-Standard Cases

Most cases of ulnar collateral ligament replacement (UCLr, or “Tommy John” surgery) follow a fairly standard throwing program and rehabilitation program. A sample throwing program once cleared to throw looks something like this:

However, not all athletes respond to such a conservative program. It is also our opinion that touching a baseball should show up significantly later in the “throwing program” than what most PT and MDs recommend. For example, in weeks 1-3, many of our athletes will never touch a baseball and instead will do primarily negative/reverse throwing with Driveline PlyoCare Balls. Furthermore, they will generally NOT throw balls at the regulation weight – 5 oz. Their first throws will often be with an overload ball (8 oz) at very low intensities to “feel” the motor patterns they should be building. Touching a baseball and throwing it brings back hundreds of thousands of reps and feelings from throwing a baseball, which is hard to […]
