Baseball is a game of incredible moments, awe-inspiring feats, and dramatic finishes. But not all of these events actually impacted the game itself or the players still to come. Moments such as Lou Gehrig’s last Opening Day appearance, the very first All-Star game, or Mickey Mantle’s first game to hit home runs from both sides of the plate are iconic not because they were game-changing plays, but because they affected the course of baseball history.

In 50 Moments That Defined Major League Baseball, Rocco Constantino provides a fresh history of the national pastime by recounting the most extraordinary and iconic moments—both renowned and obscure—that shaped the game as it moved from the Dead Ball Era, through World War II, and on to the modern era. Events include Jackie Robinson’s first All-Star Game, Babe Ruth’s 50th home run in his first season as a Yankee, Hank Aaron’s first career home run, and many more. Highlighting these moments are Constantino’s exclusive interviews with over 50 former Major League Baseball players, managers, and umpires, as they candidly share their memories and provide commentary on these impactful events. Many of the players interviewed played in the World Series or an All-Star Game, including Rod Carew, Fred Lynn, Shawn Estes, and Jeff Montgomery.

50 Moments That Defined Major League Baseball features rarely seen historic photographs of baseball immortals and modern photos of today’s stars. With two bonus chapters that include first-hand entertaining anecdotes from baseball icons and moving statements about those who helped them reach the sport’s pinnacle, this book is an engaging read for baseball fans and historians alike.
