A fast break in men's lacrosse is a quick 4-on-3 transition where the offense aims to score within 2-3 seconds using minimal passes, precise positioning in an L-formation, and decisive actions to exploit defensive rotations. Success relies on clear communication, sprinting into position, and prioritizing quick, accurate shots.

The flat break introduces a strategic departure from the conventional L formation, skillfully disrupting defenses accustomed to the standard approach. This tactical shift complicates matters for defensemen, particularly those used to stopping the ball and then rotating towards the expected first pass.
