Former MLB umpire Richie Garcia is concerned about the impact of the Automated Ball-Strike System (ABAS) on umpires, which was introduced for regular-season play this season. The system allows teams to appeal strike-zone decisions to a system based on 12 Hawk-Eye cameras. Garcia, a major-league umpire from 1975-99, said the system was embarrassing to the umpire's staff and that "nobody likes to be humiliated in front of 30,000, 40,000 people." While there is constant debate over calls, umpies were the most accurate ever last year, with a 92.83% accuracy rate, an average of 10.88 missed calls per game. Under ABS, each team gets two challenges per game and if successful, one team out of challenges gets one additional.
