The Korea Baseball Organization (KBO) supplemented the pitch clock rules ahead of the opening of the 2025 professional baseball regular season.

KBO held a meeting with the coaches of 10 clubs ahead of the "2025 Shinhan SOL Bank KBO League Media Day & Fanfest" held at Lotte Hotel World on the 20th, with KBO Judge Kim Byung-joo and Recording Committee Chairman Jin Chul-hoon in attendance.안전놀이터

Peach Clocks, which were piloted last season, will be officially introduced and implemented from this year.

The purpose of the Peach Clock, which was introduced for the first time in the 2023 season by the U.S. Major League Baseball, is to shorten the duration of the game. The measure is to impose sanctions on pitchers and batters when they violate the rule by allowing limited time in their preparation movements. Pitchers must throw the ball within 20 seconds when there is no runner and within 25 seconds when there is a runner, while batters must bat within 33 seconds.

During the exhibition game, KBO discussed detailed enforcement regulations related to pitch clock, where opinions were raised that "it needs to be supplemented," and listened to the coaches' on-site opinions. Based on the contents organized through the meeting, the following detailed rules will be applied from the opening game on the 22nd.

The batter's batting result after the pitcher's pitch clock violation is 'invalid'

Regarding the pitch clock rule that "a pitcher should start a natural motion of pitching to a batter before the pitch clock expires (the zero-second mark point), if the pitching motion is not started until the zero-second mark point, the ball will be declared immediately and the pitcher will be charged with a ball.

At this time, the batter's batting result is not recognized and is treated as invalid. If the batter or catcher violates the pitch clock, it is also a bouldered situation.

This is specified in the existing pitch clock regulations. It was emphasized once again for a clear understanding and consistent application of the regulations.

Time requests not included if batter at bat uses bat spray after swing

If a batter uses bat spray after swinging, it will not be included in the time request count. However, it will be considered that the batter leaves the batter's box when the pitcher is getting ready to pitch, not immediately after the swing. The batter's time request can be made up to two times per batter's box, and strikes will be imposed on batters who exceed this number.

Caution or warning measures can be taken if the pitcher intentionally delays the game using the remaining time of the pitch clock

Caution or warning measures can be taken if the referee judges that the pitcher intentionally delays the game by using the remaining time of the pitch clock according to the purpose of introducing the pitch clock rule, "Provide a thrilling game by reducing unnecessary game time."
