Knowing that there are still several ways and possible Bartman-like instants where the Cubs could see another playoff run ripped away from them, I'd preferred to have some of those covered by instant replay.

Lou's argument is pretty much the only valid one: time. Baseball is a long sport that if you sit down and watch for nine innings you pretty much can't get up and physically do something the rest of the day. That and umps are always trying to speed up the game. Add instant replay and then you have to take more time reviewing a play that might be inconclusive anyway. But in an era where baseball has been questioned for its integrity, instant replay will do marvels for this business.

There are so many blown calls in baseball, that at the least, homerun calls, where actual runs are on the line and umps are furthest away form the play in question, should no doubt be the first. Perhaps they should be the only. As time goes on, there will undoubtedly be calls for more things to be "challengeable" to use a football term. However, as baseball is a game that is so deeply affected by time and which the manager has so much control already over the pace of the game, there may not be any more room for it.

While time will tell about the effectiveness of replay, it is time that baseball deliver the level of truth that has been demanded of it in this digital age. The players and fans deserve it at least in this much and I hope fans of baseball everywhere will look back to 8/28/08 an a milestone day in Major League Baseball.
