Robo-umps
Robo-ump has been sold as a futuristic solution to an age-old problem: With a computer-powered strike zone, an afternoon at the park will never again be ruined by human error.

Late into a Pennsylvanian summer night, with the score tied at 7, the Lexington Legends' Jordan Pacheco takes a 1-2 pitch low and away without a second thought. But then, the umpire rings him up. Pacheco folds in two, grabbing his knees in disbelief. The missed call is so egregious it takes the announcer 20 seconds to realize what's happened.
