This book profiles forty major league ballplayers who engineered remarkable comebacks to salvage fading careers. Details of each comeback is provided along with a summary of the player's career. The comeback players range from Hall of Famers like Ted Williams and Stan Musial; to near-greats like Tommy John and Luis Tiant; to journeyman performers like George McQuinn and Tony Cuccinello.

In the absence of statistical standards to evaluate or even define comebacks, the selection of the top comeback players was based on the following criteria: historical significance, uniqueness, dramatic content, degree of difficulty, and the player's overall reputation and standing.
