The Korea Baseball Softball Association (메이저사이트KBSA) announced on the 12th that it will operate robot referees at the 77th Golden Lion National High School Baseball Championship and Weekend League Wangjungwangjeon, which will be held at Mokdong Baseball Stadium in Seoul from the 14th.
KBSA introduced robot referees from the round of 16 of the 2023 Shinsegae E-Mart Cup National High School Baseball Championship in March.
However, in the process of implementation, on-site opinions such as a sense of discrepancy between the low ball and the left and right strike zones were raised, and accordingly, after supplementation and verification, the strike zone was reset.
KBSA referees attended and applied various strike zone setting plans to high school baseball weekend league games.
In addition to this, the bottom half tried to reduce the discrepancy in the strike judgment for low balls by allowing the entire ball to enter the zone to be judged as a strike.
In addition, both the front and back sides of the home plate must pass through the zone to be judged as a strike.
In addition, the left and right strike zones were reduced by half a ball to reduce the width of the left and right, and the rear judgment surface was wider than the front judgment surface by about one ball, reflecting direct pitches that fill the inside and outside of the zone.
KBSA said, “We will continue to operate robot referees to provide fair opportunities and accurate judgments to players.” I will take it into account,” he said.
