Bauer Units, Pitch Movement, and Evaluating Pitches

At Driveline, Bauer Units have been used as a reference during pitch design since the pitch tracking technology such as the Rapsodo started to appear in 2016. We introduced Bauer Units in our original piece on spin rate and followed up with another article to define them more clearly. In this piece,...

Validating Rapsodo 2.0: Pitch Design Made Easier

As player development in baseball continues to rapidly evolve, the demand from coaches and facility owners to integrate sophisticated, reliable, and affordable technology into their players’ training plans has never been higher. In recent years, many products have entered the marketplace attempting...

A Deeper Dive into Offspeed Pitches: Pitch Classification

After looking further into fastballs, now is a good time to look deeper at offspeed pitches—particularly curveballs and sliders. We’ve talked before that one of the key parts of an offspeed pitch is how the spin of the pitch aligns with the axis. If using a device like a Rapsodo, this shows up as us...

A Deeper Dive into Fastball Spin Rate

In a previous article, we discussed the difference between cues and measurements as well as how technology is changing baseball. We now know that instead of simply repeating cues verbatim to players, learning more background knowledge of certain topics is needed. One of those topics is spin rate. As...

How Do We Generate Spin?

With increasing accessibility to tools such as Rapsodo, Trackman, and Flightscope at all levels of the game, spin rate and spin axis have largely dominated much of the recent conversation revolving around pitch design and repertoire development. This greater emphasis should come as no surprise given...

Assessments, Data, and Individualization

Individualization is seen as a must have with training programs. While this is good, it doesn’t come without some misunderstandings. We’ve touched on some of those issues before, but it sometimes seems like people get confused by what individualization means in relation to sports. At times, individu...

Scaling Velocity & Useful Spin in Offspeed Pitches

We still don’t know a whole lot about spin rate. While we certainly know more about how to use it under certain situations, we don’t know that much on how to develop better spin. Because of this, we are running smaller experiments to get a better idea of what to test and what to look for. The idea i...
