The subtitle of this book is Inside the Billion-Dollar Mystery of the Most Valuable Commodity in Sports and “mystery” is an important word. No one knows for sure why some pitchers can gain incredible endurance and others are prone to injury. Practices for building arm strength and preventing injury are built more on guesswork than science. And while new surgical procedures have allowed some pitchers to return to successful careers, they are no panacea. At the heart of The Arm is the fact that throwing an orb overhand a 100+ times in succession is an unnatural action, and the mystery is that anyone manages to do it without injury rather than why some pitchers can’t avoid injury.
At the heart of this book, Passan provides eyewitness documentation of two contemporary pitchers – Todd Coffey and Daniel Hudson – as they undergo Tommy John surgery and attempt to return to pitching at the top level in Major League Baseball. In between there stories, Passan interviews various baseball legends: Sandy Koufax, whose Hall of Fame career was cut short in the days before surgeries that could’ve extended the life of his arm; Nolan Ryan, the opposite extreme, a pitcher known for his remarkable longevity despite refusing surgeries; and of course, Tommy John, whose eponymous surgery changed baseball. The career of orthopedist Frank Jobe, who humbly named ulnar collateral ligament reconstruction for his patient rather than himself, is also documented.
Outside of Major League Baseball, Passan investigates the increasing pressure in youth sports to specialize in one sport early and for coaches to overuse their young players’ arms in games. Tommy John surgery is skyrocketing among adolescents. An exploitative youth sports industry has also emerged that encourages young athletes and their families to pay to participate in showcases on the hopes of attracting attention of Major League scouts. Passan also visits Japan where the traditionalist view of “pitch until your arm falls off” in high school baseball is just beginning to be challenged by the younger generation.
The mystery of the arm is not resolved in this book, but Passan does an excellent job documenting what we know about pitching and exposing a seedy underside of our national pastime
