After the game against the LG Twins in Jamsil on Monday (six innings and two runs), Kim was asked by reporters about the automatic ball-strike system (ABS). The team has shown poor performance, as evidenced by the fact that it is the “worst season” for Kim himself. Although his earned run average was in the early three-point range until the last season after his debut, the team soared to the five-point range (5.13) this year. On-site, some say that Kim’s unexpected slump is because his main weapon, sliders, does not fit well with ABS.안전놀이터
Under the ABS system, which is called a “robot referee,” strikes and balls are divided by a dedicated camera installed in a baseball stadium, not by a referee (person). Strike zones are sometimes applied differently depending on the height of the batter. For a player who is 1m80cm tall, the top is 101.43cm, the bottom is 49.75cm, and the top and bottom are 107.7cm and 52.52cm, respectively. The left and right standards will be expanded by 2cm from the home plate (43.18cm). In addition, it can be judged as a strike only when the upper and lower height standards are met in the middle and end of the home plate, which is important to Kim Kwang-hyun. Analysts say that it is difficult to meet the upper and lower height standards of the two places because his slider angle is large.
Kim made his stance cautiously. “If you pass through the front (meaning the middle and the end of home plate) and not through the back, wouldn’t it bend that much? Then, wouldn’t it be if you put up a spot where ABS is taken or a trajectory that penetrates onto the electronic display board?” The result of ABS’ strike and ball judgment is delivered to the tablet PC in the dugout. However, pitcher and batter cannot be immediately identified in the ground. While paying attention to judgment, it ends up ruining the game.
“Batters have some complaints. Pitchers are just not expressing their complaints,” Kim said. “I think one way (to operate in a more transparent manner) is to display such a trajectory or something that fans can explain on the electronic display to minimize complaints. If we can check it right after throwing it, both pitchers and batters will be able to accept it to some extent.”
