1. Managers get one "challege", like in football. No flags, however. A manager simply tells an ump that he would like to challenge the call with a 5th ump looking at a monitor in the booth(or use 3 in the field and 1 in the booth)- safe, out, fair, foul, HR, not a HR(everything but strikes and balls). Everyone who proposes these ideas fail to realize the implications of this. What if an OF traps a ball with runners on base and its called the third out, where do you put the runners? What if the runner fell down and could have easily been thrown out after the trap, do you assume he would have been thrown out. What if it there was 1 out and a runner was tagging and was then thrown out for a double play, do you give the batter 2nd base since he would have gone there on the throw to home? What if a ball is ruled a hit and runners advance, but replay shows a catch, do you put the runners back? What if you had Carlos Gomez on 3rd, do you assume he would have scored because he is fast, but if it was McGehee you dont get the run because he is slow? What if you have R1, R2, double play attempt with 1 out, runner called out at first but R2 was trying to score? Reaplay shows runner safe at first, if he was called safe at first on the field the 1B would have had a chacne to throw the runner out at home. Does the runner get to score, go back to 3rd. The defense would surely complain that they had a chacne to throw him out? The list of special situations which would have to be applied to replay situations would fill volumes and you couldnt just show it on the screen to the average fan. 3. If the call stands, the manager cannot challenge for the rest of the game. Also, the manager cannot leave the dugout to talk to the umpire for the rest of the game. Upon doing so, he is ejected. I never understand this, isnt the point of replay to get the call right, what possible sense does it make to have a clause like this. What if Jim Leyland was wrong on some call eariler in the game and was out of challenges? Then everything is all fine and good? This could be possible. The game actually would speed up under such rules. No more 5 to 10 minute manager arguments. A little too idealistic here. Do you honestly think this will speed up games? Everyone acts like every call in baseball is obvious, I have DVR and a few points are that 1) whenever I think the ump was wrong there were right, 2) There are MANY plays where you cannot tell what the right call is using instant replay. Also, if you are giving this 5th umpire this job he is giong to take his sweet time, just like in the NFL, because they know the same views they are getting will be replayed on ESPN for a week, so they are going to make 100% sure they are correct, they will not just take 1 look in 15 seconds and say OK we have a decision, play ball. Even the play last night it appeared that the ball moved in Galarraga's glove making it not 100% obvious that he had complete control of the ball, it would have probably been reviewed a dozen times by the 5th ump. Managers argue with umps for many reasons and they are not to just question calls, it is mostly to stand up for their players. Also, they certainly do not last for 5 minutes. My point is that I dont care if the call is wrong, IT IS A GAME. Plus, wrong calls RARELY happen in situations which actually cause the wrong team to win. Having controvesial things is interesting and memorable and make baseball a great game. There are millions of people all over who think baseball is "boring" are overreacting to this and talking about instant replay, its good for the game. Its fun to talk about blown calls and would could have beens. The home fans boo when a call goes against them no matter what and that is part of the game. The game would slow down far too much for no reason because some call reversal wont change the outcome and everyones time will just be wasted.
