A pitch clock displayed at Werner Park in 2015

A pitch clock (also known as a pitch timer) is used in various baseball leagues to limit the amount of time a pitcher takes before throwing a pitch and/or limit the amount of time the hitter uses before they are set to hit.

Various baseball leagues and tournaments around the world use 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.
