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...

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...

Reviewing Offspeed Pitches and Elbow Torque

With new research developments in other labs and our own facilities, we felt it was a good time to update our data set on offspeed pitches. Previously, we looked at offspeed pitches and were able to come close to replicating peer-reviewed research with the motus sensor. Essentially, fastballs were t...
