The baseball expert famously known as PitchingNinja explores the revolution that has given pitchers an unprecedented advantage in today's game.

Pitching dominates baseball as never before. Spin rate, sweepers, 105 mph fastballs--all have become standard when evaluating pitching arms and techniques and are familiar lingo in discussion and analysis of the game. Gone is the era of the swaggering power hitters. Batting averages are close to the deadball era; team records for strikeouts are broken and then broken again. The game has fundamentally changed, and hitters may never catch up.

Rob Friedman has closely observed this revolution that has transformed baseball for both players and fans. A self-taught coach who has evolved into a sought-after pitching analyst by players, teams, and sports networks, he breaks it all down in this fascinating chronicle.

Friedman spotlights the influential figures behind this transformation. Tom House, a former MLB pitcher turned coaching visionary, utilized cutting-edge technology to refine the techniques of legends like Nolan Ryan and Randy Johnson. His unconventional methods paved the way for a new era shaped by the collision of technology and tradition. Brent Strom, another MLB pitching insider, has used data to revive flagging careers--helping stars like Justin Verlander, Gerrit Cole, and Charlie Morton to use technology to enhance their performance. Friedman also celebrates the rise of external innovators like Kyle Boddy of Driveline Baseball, who has trained elite pitchers such as Trevor Bauer, Shohei Ohtani, and Clayton Kershaw, using advanced analytics and technology, as well as others.

Peppered with insights drawn from interviews with top pitchers, Unhittable is an insider's look at how these advancements have been used by players themselves, and how they have fundamentally changed America's pastime.
