Im all for a computer ump. Have a green light and a red light behind the plate, one for balls and one for strikes. The actual calls in the IF would be tougher to figure out, but the human error part is starting to get ridiculous in some of these sports.
Sensors on the ball as well as the mitts and cleats for the infielders.
