America's past, the great game called baseball. Baseball has been around since the late 18th century. It has evolved a lot since then. The equipment of the game itself has changed. For example, more protective helmets and better designed bats are used. These aren't the biggest changes in baseball, however. The biggest change in baseball is undoubtedly the introduction of instant replay. Baseball currently only uses instant replay to review homeruns. Much more can come out of instant replay than just reviewing homeruns. MLB needs to expand uses of instant replay. Referee errors can be costly, can cause teams to lose and even prevent a record from being broken. With the expansion of instant replay, umpire errors can be eliminated and change the game of baseball for the better. Baseball, like other sports such as football and soccer, uses umpires or umpires to regulate the rules. The number of officials used in a game depends on the type of game, regular season or postseason game. Four referees are used for regular season games. Six umpires are used for playoff games and the World Series. During regular season games there is an umpire located behind the plate, first base, second base and third base. Games conducted during the postseason the umpires are located in the same place, but two additional umpires are positioned on the ballpark's foul lines. Officials essentially work as a team to make the best call possible. There is the head referee and the referees on the field. The umpire-in-chief stands behind home plate. He or she is responsible for calling balls and strikes and also determining whether a run is called out at the plate. The remaining referees are field referees. They are in charge of... half the paper... the replay will be effective. As long as trainers are given a certain number of challenges, the length of the game will not be extended too much. Furthermore, if only some plays are made reviewable, managers and referees will have common ground, which can lead to a reduction in ejections. Referees not seeing plays clearly has become a common occurrence. Since referees cannot see the play clearly, they make bad calls, which prove costly. The results of bad calls made by umpires can be seen in the 1985 World Series and the near-perfect game pitched by Armando Galarragas. The Royals won, when the Cardinals should have won, and Armando should have pitched a perfect game, but didn't. If horrible calls made by umpires could be eliminated simply by expanding the uses of instant replay, fans across the league should join the bandwagon and help push for change in MLB.
