Why no Replay?

So I saw the end of the Angels-White Sox game and was shocked at the way it ended. I am still amazed at sports that do not use Instant Replay. Why when there is the option to use instant replay do major sports not use it? The game should not have ended, that much is clear from the tv replays. The umpire made the wrong call, yet the main fault is not his, its Bud Selig’s and all those who refuse to be dragged into the 21st century. Replay would not add that much time to games that are already way too long. Heck it might even speed games up since there would be less hesitation on the part of umpires and less need for the overly dramatic screaming in the face antics of Managers.
