Baseball and instant replay

Query: Baseball officials say they don't want to expand the use of instant replay because it would slow the flow of the game. But how would a quick check of a video screen be any different than that lengthy huddle the umpires engaged in after that fifth inning shoestring catch by the Phillies' shortstop, Jimmy Rollins? Everyone is full of praise for that huddle today, because the umps came up with the right answer. But wouldn't a huddle with the addition of actual relevant data to consider be quicker? Or, at least, cause no more of a delay?

Also, isn't it a bit rich for MLB to be talking about the pace of baseball games at all? There's at least 45 minutes of fat in every game these days: bat-twiddling, dirt-kicking, mound conferences. (Ask your father or grandfather about the days when games would wrap up in under two hours.) Why not crack down on that stuff and, as in football, give the umps some high-tech help, especially when the video evidence is as clear as it was last night.
