running the pipe

Running the pipe is the wrestling-derived name for the sweep single — the single-leg finish in which the attacker drives in a circular path around the opponent’s standing leg, “running” past the opponent’s defensive frame to bring them to the mat.

Etymology. “Running the pipe” is American folkstyle and freestyle wrestling vocabulary for the circular-drive finish to the single-leg. The “pipe” metaphor describes the trapped leg as a fixed vertical axis the attacker circles around — like running around a pipe stuck in the ground — while pulling the opponent off-balance toward the sweep direction. The term predominates in spoken wrestling vocabulary and instructional contexts; the term entered no-gi grappling and submission wrestling through wrestler cross-training. The BJJ vocabulary generally uses “sweep single” or just “running the single” for the same finishing mechanic.

Mechanics. The finish requires the attacker to hold the opponent’s leg locked against their chest while driving in a circular path around the opponent’s centre of gravity. The circular motion pulls the opponent’s posted leg out from underneath them — without a stable base, the opponent’s centre of gravity continues its trajectory and the takedown completes. Hip access on the captured leg is the prerequisite for the finish to transfer through.

Cross-reference. BJJ and English-speaking no-gi use “sweep single” or “running the single.” Full mechanical coverage on Sweep Single.
