The greatest players in baseball history are honored in the National Baseball Hall of Fame in Cooperstown, New York. Fans and sports journalists often lament about players who might have joined the immortal ranks, if only fate--circumstances, injury or even death--hadn't intervened.

Presenting a "who's who of what-ifs," this book focuses on 40 well known non-inductees, such as Tony Conigliaro, Denny McLain and Jose Fernandez, along with many others all but lost to history, such as Ross Barnes, Charlie Ferguson and Hal Trosky. Also included are more than 100 "honorable mentions" covering all of pro baseball history, from the 1860s to the 2010s.
