Goold: Rapsodo's revolutionary spin on pitching launched locally, from Cardinals' backyard

Aaron Schnurbusch, a former professional pitcher who now works at Rapsodo's St. Louis office, gives a demonstration on the company's pitching tools and the immediate feedback the motion capture technology gives of a pitch's spin rate, its access, its velocity, and how efficient it was against gravity. The company's North American operations have called St. Louis home for more than a year, moving off Manchester in July 2018. (Photo by Derrick Goold)
