A Week in the Life of an RPP Data Intern


I joined RPP Baseball as a Data Intern this past September, and was very excited about the opportunity to learn all of the different aspects of applying technology to training pitchers and hitters. Little did I know how all-encompassing it would be. The process of working and training daily with the latest technology has proved to be an amazing experience for my personal development as a professional in this industry. Whether I am working with Rapsodo Pitching, Rapsodo Insight, Blast Motion, HitTrax, K-Vest, or assisting with our bio-mechanist on a full blown Qualisys motion capture system, I am amazed at the impact that data and technology can have on player progression and talent maximization. I decided to write this article, not only to summarize how much I have learned in this position, but also to help provide a road map for all those that may come after me.

Wondering What Happens to all the Data from Motion Capture?


Today, we’re lifting the hood a tiny bit…. Much is written about the value of data and its potential application to training pitchers. But a full-blown motion capture system takes this type of discussion to a whole new level. A typical mocap session involves attaching over forty markers to a pitcher’s body. After a pitch is thrown off the mound, the system combines the views of a dozen or more cameras to create a 3D avatar of the athlete, which then allows for preparing angular measurements of various body parts, up and down the kinetic chain.  What happens to all that data from the avatar is what we are going to review here…

How Much Scap Load… What is Efficient?

Scap Load

Horizontal shoulder abduction, scap load, elbow angle are terms originally coined by Paul Nyman and which refer to the retraction of the shoulder blade (scap) prior to the arm cocking phase. Call it whatever you like, but the degree to which your scap “loads” matters. Horizontal abduction helps with layback and setting up the rest of the arm action once the lead leg blocks, decelerates and sends energy up the chain. Continue reading “How Much Scap Load… What is Efficient?”

What Makes Kevin Gausman’s Splitter So Effective?


With San Francisco Giants ace Kevin Gausman generating NL CY Young consideration for much of the 2021 season, the effectiveness of the splitter has become a hot topic of conversation. Let’s take a deep dive to gain a better understanding of the characteristics of this particular pitch. A splitter is an off-speed pitch that should play directly off of a fastball, similar to the use of a changeup. It has reduced spin rate due to a stiffer wrist and wide grip (fingers placed on the outside of the baseball) which induces downward movement with occasional horizontal break. Continue reading “What Makes Kevin Gausman’s Splitter So Effective?”

A Day (Week, and Month) in the Life of a College Hitter at RPP – Part 2


In Part 1 of this article, we covered the information we gathered from the initial assessment on this specific college athlete and how we addressed the disconnects we felt could be easily improved. Part Two will now dive into the work this athlete put in through the remainder of the summer, as well as the information we gathered from reassessments and the changing landscape of our training environment. Continue reading “A Day (Week, and Month) in the Life of a College Hitter at RPP – Part 2”

A Day (Week, and Month) in the Life of a College Hitter at RPP – Part 1


The summer season can be a great opportunity for college baseball players to go off and play in various summer leagues throughout the country. Some of the top tier guys go to the Cape Cod League or other competitive leagues like the NECBL and Northwoods for an opportunity to play in front of pro scouts and elevate their draft stock. Younger guys may head off to smaller leagues where pitchers can get a ton of innings and hitters can get plenty of ABs to supplement those they might not have gotten in the spring. But for other guys, the “In-Betweeners,” the summer provides a different, maybe less conventional opportunity – a chance to pop open the hood and work on their game to return to school in the fall a more efficient athlete from both a hitting and strength standpoint. Continue reading “A Day (Week, and Month) in the Life of a College Hitter at RPP — Part 1”

Where Mocap Can Help Fill the Gaps!


Most of you already know that while we are big believers in using data/tech, the human element should never be replaced, just simply “enhanced”. So let me start with this great quote by PT (and super smart guy) Bill Hartman:

Technology provides answers that are stored or calculated. It serves me. It is not creative or curious nor has the capacity to ask the important questions. Those qualities are purely human.

However, as I have said before there is great value to data, especially in areas where you can’t necessarily observe what’s happening during the delivery, but it can be measured.  Today, we’re going to look at an example of the merging of the eyes and data. I decided to write this article after reading a recent thread posted by RPP Pitching Coordinator Justin Friedman. Continue reading “Where Mocap Can Help Fill the Gaps!”

How Can Poor Hip Mobility Impact Arm Health?

hip mobility pitchers

Improving arm health in pitchers is a topic which is typically viewed in reference to the arm itself rather than all the other parts of the body. This way of thinking can potentially lead to arm health issues. When assessing the lower half of a pitcher’s mechanics, often hip mobility issues surface and should be addressed. The purpose of this article is to help provide insight on how we initially assess hip mobility; common issues associated with a lack of hip mobility and ways to improve hip mobility issues. Understanding that fixing poor hip mobility is not an overnight fix is critical in helping the expectations of the progress that can be made if an athlete is consistent in their training.
