Former MLB umpire Richie Garcia has voiced strong concerns about the introduction of robot umpires, calling the Automated Ball-Strike System embarrassing to human officials. Garcia, who umpired from 1975-99, criticized MLB for undermining umpires' authority by implementing a system he believes is controlled by 'computer geeks' rather than baseball professionals.

MLB's ABS system uses 12 Hawk-Eye cameras to track pitches, allowing teams two challenges per game with one additional challenge in extra innings. While umpires have improved significantly, posting a 92.83% accuracy rate last season with an average of 10.88 missed calls per game, technology has set a new standard for perfection that human officials cannot match.

Spring training results show mixed outcomes, with Philadelphia batters achieving a 61% challenge success rate while Arizona and Texas struggled at 33%. Catchers like St. Louis' Pedro Pages went 8 for 8 on challenges. The system defines strikes based on crossing the plate at specific batter height percentages, differing from the traditional rule book strike zone. As the technology becomes permanent, the debate continues over whether it enhances or diminishes the human element of baseball.
