if a baseball is the width of two or three baseballs away from the "zone" (dynamic based on player usually), then providing a way to challenge the call (it was called a strike when it is clearly a ball) is completely fair and retains the soul of the game. Baseball is really a game of fairness. There's no "buzzer beaters" or timed sessions. Everyone has their chance per inning to impact the game. In a game of relative fairness, adding more strict honesty when it comes to something like this will only improve the game.
