BASEBALL Sources: All AAA parks to use electronic strike zone in '23
The electronic strike zone will be used in all 30 Class AAA parks in 2023, sources told ESPN, seemingly another significant step toward the implementation of the technology at the big league level in the near future.
The Automatic Balls and Strikes system, commonly referred to as ABS, will be deployed in two different ways. Half of the Class AAA games will be played with all of the calls determined by an electronic strike zone, and the other half will be played with an ABS challenge system similar to that used in professional tennis.
In 2019, the independent Atlantic League used the electronic strike zone in an all-star game, and that same year, the Arizona Fall League was played with the ABS. In 2021, the ABS was deployed in some Class A parks. Last season, the full ABS was used for some Class AAA games.
The first-year feedback on the challenge system was surprisingly positive, according to club staffers, with some in the industry beginning to believe that this might be a good first step in utilizing ball-strike technology.
