A lot would have to happen. Depending on how large this screen is you're virtually eliminating the pitcher as fielder. We could see real negative effects to the actual game like more bunting for example. More soft liners can result in hits. While a ball that is torched hits the screen and deflects to a fielder for an easy play.
I just don't think it will ever happen. Or should happen. It's just an unfortunate thing that happens in the game of Baseball. s***** things happen.
