Only a few weeks ago baseballs owners elected to institute video replay into the game. However at this time no one not even the owners who elected to institute this technology knows how it will work. There have been no decisions made to what extent the technology be used for, for example will it be used for only pitching, how about calling a player safe or out. Also how often will this technology be used, will we see it correcting umpires at every turn or will it be used like the challenge system in which football and tennis have implemented?
In my opinion baseball needs to use this technology the same way football and tennis have implemented video replay with the challenge system. Using the challenge system allows for the umpires to continue to do their job with little intrusion. We do not need to see umpires being overturned constantly by video replay. However with the challenge system those obvious mistakes can be rendered. The umpires are only human and do make mistakes but overturning their every call will just make the game look silly.
Video replay can be used to benefit the game. But it is not long before the season starts, so the owners and players must agree to rules of this system soon. Hopefully for the good of everyone involved they do not over implement the system and ruin the game. Baseball needs to find a way to implement the system, hopefully in a way that will not ruin the roots of the game.
