Pitch clock

A pitch clock (also known as a pitch timer) is used in various baseball leagues to limit the amount of time a pitcher uses before he throws the ball to the hitter and/or limit the amount of time the hitter uses before he is prepared to hit.

Various baseball leagues and tournaments around the world have started using a pitch clock to speed up the pace of play. Major League Baseball (MLB) began using a pitch clock in the 2023 season following a period of tests on MLB partner leagues, minor league baseball, and college baseball.
