I know that they have the ability to review whether a ball is inside the foul pole or not. This is a great advancement with technology use. However, would it be better if say there was a 5th umpire who watched the game from a tv. He would be able to talk to the 4 man crew. He would call balls and strikes instantaneously. On close run plays such as the attempted steal we just saw in the Phils/Cards game he would be able to overturn the decision seeing as the foot definitely touched the bag first and did not come off. Thoughts?
