Baseball technology has come a long way since the days of the Iron Mike. Trajekt Arc uses data to mimic the way balls spin and break from every big league pitcher and has for the first time been approved by Major League Baseball for in-game use this year in batting cages. Using video and mechanics to turn the data into reality, the robot allows a hitter to see recreated offerings from the pitcher he is about to face. Dodgers two-way star Shohei Ohtani said he used Trajekt to view his pitches from a different vantage point.
