MLB introduced electronic strike zones to be used in all 30 Major League Baseball parks beginning in 2023, in the latest use of technology to make the sport more sound. Half of the AAA games will be played with totally automated strikezone calls, whereas the other half will be played with a challenge system.Fans expressed various emotions at this announcement, as umpire calls have been a major talking point in important games involving their fans. With the use of technology, that might seem to be fixed.The Automatic Balls and Strike system, referred to as the ABS system, will be fully automated in half matches with no umpires at all. In another set of matches, the ABS will have a challenge system quite similar to tennis, where umpires will make strike calls, but players and coaches from both teams will have the right to challenge the decision.Buster Olney@Buster_ESPNSources: All AAA parks to have robot umps in '23 espn.com/mlb/story/_/id…2687712Sources: All AAA parks to have robot umps in '23 espn.com/mlb/story/_/id…Each team is expected to receive three challenges per game and will retain its challenge if successful. Depending on the feedback from both sets of games, the MLB will be motivated to take future calls. The administration doesn't have any plans to introduce it in the big leagues, but might be interested to see if everything works out well.Fans went on to Twitter to voice their opinion on MLB's decision. One fan directly waved goodbye via a GIF to umpire Angel Hernandez, who has been accused of making controversial calls in the past.Stacy NYC@Hustlediva1@Buster_ESPN Buh bye Angel Hernandez5@Buster_ESPN Buh bye Angel Hernandez https://t.co/RUllnLABnoAnother fan suggested that the utter shock the umpires will have when their decision gets overturned will be worth watching.Joe Hutzal@JoeHutzal@Buster_ESPN @JeffPassan They don't need robotic umpires to call the the game. They just need the robot to shock the hell out of the umpire every time he gets it wrong! That would get them putting in the effort they should be and the problem would be fixed.81@Buster_ESPN @JeffPassan They don't need robotic umpires to call the the game.

How do they adjust the ABS strike zone for different height players?8@Buster_ESPN Strike zone is knee to shoulder. How do they adjust the ABS strike zone for different height players?David Haar@davidhaar@Buster_ESPN Curious how this works for players that are bigger/smaller or for players that have straight up batting stances versus a big crouch in their stance. Are robot umps able to differentiate accordingly for what would be a different strike zone size?@Buster_ESPN Curious how this works for players that are bigger/smaller or for players that have straight up batting stances versus a big crouch in their stance.

The ABS system was used by the independent Atlantic League in 2019, and the Class A Southeast League recently used it in 2021.The results from the Class A Southeast League were mostly positive, as officials noted that this gave a more strategic balance to the game where players have to be more diligent in using up their challenges. Moreover, certain club officials noted that defensive play needs to be more responsible, as the ABS system will scrutinize everything that a base umpire might have evaded in the past.
