Can an app make the call on baseball umpires?

With the World Series just around the corner, we’re hearing a lot about players’ stats. But another issue is when an umpire gets a call wrong. Major League Baseball is trying to make those instances less frequent. Over the summer, robot umpires helped officiate a minor league game. The goal is not only to improve accuracy of the calls, but to speed up the game and get more butts in the seats. But Boston University finance professor Mark Williams thinks there’s a way to use an app to make human umpires better at their jobs before we turn the reins over to the bots. We talk with him about the idea behind it.
