Yea, but that would take some of the fun out of baseball. Umps are a unique part of the game. Who will the fans heckle if you get rid of them? Who will coaches blame losses on? We would no longer get to see coaches break it off in an ump and get tossed. IMO that is part of what makes baseball special. Everyone loves seeing a coach give a good ass chewing to an UMP and sometimes that can completely flip a game when a team rallies around their coach.
