theathletic.com/spinrate Drew welcomes 3Motion AI chief scientist,
Dr. Mike Sonne, to Spin Rate! Dr. Sonne studies biomechanics and
how bodies' motions can affect things like pitching...maybe even
pitching that's assisted by certain substances. He and Drew unhinge
the truth from fiction in the foreign-substances-on-baseballs
discussion. Spider Tack, sunscreen, Elmer's Glue, whatever pitchers
use, should it be viewed as a performance enhancer? How does it
affect a baseball? What changes have been made to baseballs,
themselves, over the last couple of years? Why is Nate Pearson
still battling control issues? Dr. Sonne breaks down Pearson's
offerings. He also does the same for Alek Manoah. Lastly, the duo
dives into Toronto's pitching development approach/results. Follow
