Should baseball institute instant replay for disputed calls on the field? The rash of missed or disputed home run calls this week has only intensified the argument for bringing baseball into the twenty-first century and more in-line with its football and hockey brethren. It isn’t a question of the abilities of the crew in blue; it takes unparalleled focus to handle an intense nine-inning contest that may last well over three hours. More so, the sole purpose would be to give umpires a fifth, unbiased view of the play to ensure that there would be little doubt left on the field.
