A standard lacrosse contest is divided into four distinct periods of play. These periods are commonly referred to as quarters. Each quarter provides teams opportunities to score and strategize. The game clock is managed separately for each of these segments, stopping for various reasons, such as fouls and out-of-bounds plays.
The structure of a game into segments offers a framework for pacing the competition. Coaches utilize the breaks between these periods to adjust tactics, substitute players, and motivate their team. Historically, the four-segment structure has remained consistent across different levels of lacrosse, from youth leagues to professional competitions, contributing to the sport’s organized and predictable nature.
