Unhittable: are the modern era’s weightlifting, analytics-fueled pitchers too good?

A new book explores how technology and a host of maverick innovators have given rise to an exceptional crop of baseball players

In a 1940 publicity stunt, the Cleveland Indians’ flamethrowing pitcher, Bob Feller, tested which was faster: One of his own blazing deliveries, or a motorcycle. Feller’s pitching won, hands down. But today, Feller’s once-remarkable speed has become commonplace, even bettered, as major leaguers routinely pass triple figures on the radar gun. The secret to this arms race? The advances in pitching analytics,often authored by people without any previous baseball pedigree.

That’s part of the narrative of Unhittable, a new book by one such individual – Rob Friedman, more commonly known to his online followers as PitchingNinja. The book’s subtitle says it all: How Technology, Mavericks and Innovators Engineered Baseball’s New Era of Pitching Dominance.
