One scene that caused an unusually large number of judgment costs in the KBO League this year is 'Check Swing'. Video reading of the check swing will finally take effect on the 19th.

The KBO League initially prepared with the goal of introducing the 2026 season. The year 2025 was a trial run in the Futures League.

However, as the controversy over the misjudgment became more frequent in the first half of the year, voices calling for early implementation grew. Accordingly, KBO made a decision through the 5th Executive Committee in July. The test, which has been conducted since the 22nd of last month, has been completed.




All readings are made through KBO cameras. It was installed in the home stadiums of 10 clubs, including Jamsil, Gocheok, Incheon, Suwon, Daejeon, Daegu, Gwangju, Busan, and Changwon. The second stadium, including Cheongju, Pohang, and Ulsan, is still in place.

The difference from regular video reading is 'opportunity'. Video reading can be applied twice during regular innings, and if all are reversed, one additional time will be added. If the check swing succeeds in overturning, the opportunity does not disappear. If you go into extra time, you will have one more chance. This will also be maintained if the reversal is successful. A KBO official said "In theory, it is unlimited."

The swing standard is whether or not the commonly accepted bat angle exceeds 90 degrees.




In fact, there is no clear regulation on whether or not to swing or not. There are no stipulated rules in baseball rules. It was ambiguous to be subject to video review because there was no basis. The rationale was ambiguous because the batter could give a strike if the referee considered that he had an intention to swing.

In other words, it means `to decide.' The bat angle of 90 degrees is only a standard that is normally accepted.

With the introduction of video reading this time, the standards were clearly established through the Rules Committee.




You just have to look at the end of the bat. Even if the bat passes through the home plate, it is the North Wing if the angle does not exceed 90 degrees. Conversely, if the bat did not pass through the home plate, but the angle exceeded 90 degrees, it would be declared a swing.

KBO does not consider whether the bat has crossed the front of the home plate or the position of the handle or the body rotation, and the decision is made based on whether the angle of the end of the bat has crossed the baseline. The bunting attempt is not subject to a check swing video reading'

In the case of strike-out not-out, the defense side is somewhat advantageous. If it is reversed to a non-out strikeout through video reading, it is judged as out even if the defense has not tagged the batter, thrown to first base, or touched the base.

If the reversal of the decision affects the subsequent play, it is possible to rearrange the runners at the judgment of the referee team leader. The KBO said 'Based on the circumstances when the judgment was made correctly from the beginning, the position of the runner may be rearranged with the advice of the reading center in consideration of minimizing damage or disadvantage or excessive profits caused by the wrong initial judgment.'

Due to the decision of the check swing this season, it was often shown that loud voices came and went between the referee and the coach.

Hanwha coach Kim Kyung-moon said, "(I think it went well) when he heard the news of the video reading of the check swing last month. Checkered swings are uncomfortable even if they benefit from it. In fact, it can be okay normally, but when it is directly related to the victory or defeat of the game, it becomes very sensitive. So it's good to be fair to each other, he actively agreed with the KBO's decision.

KBO brought a test period to self-analyze cases of check swing that occurred in the second half of the game to stabilize the system of each stadium. In addition, considering that the check swing video review is a new rule to be introduced during the season, the detailed enforcement regulations were explained directly to the coaches of each club and notified in advance to the clubs and squads. In addition, in order to reduce confusion at the site and facilitate reading, meetings were held for referees and video reading center officials so that they could familiarize themselves with the detailed enforcement regulations. KBO expected that through the implementation of the check swing video reading, the accuracy of the judgment and the fairness will be strengthened to increase the satisfaction of the field and fans.
