Accurate calls should be the top priority, and instant replay helps provide them  The main goal of an umpire is to make accurate calls. Umpires are meant to ensure that a player who is out is called out, for example, and that a foul ball is ruled a foul ball. When an umpire makes an incorrect call, he is falling short of fulfilling his primary responsibility. As the official rules of Major League Baseball instruct umpires, “The first requisite is to get decisions correctly.... Umpire dignity is important but never as important as ‘being right’” (Official Baseball Rules, Rule 9.05). [1]  Without a doubt, instant replay helps to improve the accuracy of calls. When a play can be reviewed after the fact, in slow-motion, from multiple angles, it’s almost inevitable that the result will be a more accurate judgment. Instant replay serves as an additional tool for umpires, allowing closer examination of events. By providing umpires with an extra set of eyes, video cameras will better enable umps to fulfil their purpose.  [1] Major League Baseball, Official Baseball Rules,  .
