It was rough to watch. Pitchers stuff are ridiculously nasty these days so I do sympathize with umpires that are calling the game. Having said that, it is silly that the broadcast can show the balls and strikes the instant the pitch crosses the plate. Make the umps wear an earpiece and have the robots tell them whether it is a ball or strike.
plus this will speed up the game as less players and coaches will complain about the strike zone.
