Behind the scenes, at least seven Major League Baseball teams are training their hitters with intelligent pitching robots. The teams will not go public yet for competitive reasons, but these robots can potentially change the way every professional ballplayer gets ready before a game. Guest Joshua Pope is the co-founder and CEO of Trajekt Sports, creator of the first pitching machine that uses advanced robotics and AI to recreate any pitch imaginable in the exact style and delivery matching individual players. The introduction of the Trajekt Arc means that (hypothetically) slugger Vlad Guerrero Jr. could practice against the robot version of ace Justin Verlander moments before facing the real one! In this episode, Joshua tells Jon the physics behind his creation, how it began as a conversation with high school friends, talks about the novelty of MLB pitchers trying to bat against “themselves,” and ponders the possibility of his technology showing up at amusement parks and baseball stadiums for the fans.
