From the moment of its inception, the quintessentially American sport of baseball has included cheating. Sometimes that rule-skirting is embraced as ingenious hijinks; other times, reviled as an unforgivable trespass. But what exactly is the difference? Why is skipping bases less egregious than signing underage players? Is sign-stealing evidence of ingenuity, or does it fundamentally change the nature of the game?

In Intentional Balk, nationally-recognized baseball historians Dan Levitt and Mark Armour examine cheating in baseball as the pursuit of a competitive edge that in other endeavors might be heralded as innovation. Wherever you come down on the question, Intentional Balk offers an engrossing chronicle of America's pastime and the players, coaches, groundskeepers and management who for more than 150 years have sought any advantage to win at all costs.
