LAS VEGAS – Most baseball fans won't forget the controversial call in Game 6 of the 2019 World Series between the Houston Astros and the Washington Nationals when runner Trea Turner was ruled out because of interference. Umpire accuracy is a frustration for fans and players in nearly every game. This season, MLB has launched so-called "robot umpires" in 11 Pacific Coast League Triple-A teams, putting it one step away from reaching the major leagues, to improve accuracy and reduce delays. The automated balls and strikes system (ABS) debuted in a Las Vegas Aviators' game earlier this month. As cool and bizarre as it would be to see "Jetsons"-style robots on the field, most fans won't notice the actual device -- eight surveillance-looking cameras at the top of the bleachers.
