Dump Finish
Genusダンプフィニッシュ(Danpu Finisshu)
TransliterationTranslation: dump finish (katakana)
Overview
The Dump Finish completes the single leg by lifting the captured leg high while rotating the opponent over it, 'dumping' them sideways or backward onto the mat. [1] The attacker elevates the captured leg to hip height or above, then uses a combination of lifting and rotational force to tip the opponent past their balance point over the elevated leg. [1],[2] The dump finish is effective when the opponent is resisting by hopping toward the attacker, as their forward momentum can be redirected into the rotational dump. [2] The finish typically results in the attacker landing in side control or a scramble position. [2],[3]

Biomechanical Mechanism
Primary Action — Isolation of one leg — controlling a single support point destabilises the opponent's base
Joints Involved — Attacker's lead knee (penetration step), hips (level change and lifting), opponent's knee and hip (controlled)
Force Vector — Lateral and upward — lifting or sweeping the captured leg while driving the shoulder into the opponent's body
Finishing Mechanic — Varies by finish — run-the-pipe (forward drive), trip (inside/outside foot trip), or lift (elevation of captured leg)
Position & Entry
From wrestling stance — Level change with a penetration step, drive head into opponent's hip, secure one leg and lift or drive to finish
From collar tie — Use head control to set up the shot, change levels and shoot to the lead leg
From reaction to opponent's attack — When opponent overcommits, catch the exposed leg and counter into the single-leg
Variants
Inside single — shooting to the inside of the lead leg, head inside position
Outside single — attacking from the outside of the lead leg
High crotch — securing the thigh above the knee with head in the hip
Low single — attacking the ankle from outside range without deep penetration

✓Elevate the captured leg as high as possible — above your hip if you can
✓Once elevated, rotate the leg over and to the outside while driving your head into their chest
✓The opponent's weight is entirely on one foot; the rotation topples them over the captured leg
✓Use a quick hip pop to assist the elevation before rotating
✓Keep your grip tight on the thigh and drive through the rotation — don't let the leg drop
✓The dump works best when the opponent is standing tall and not crouching to base out
Common Mistakes
!Not elevating the leg high enough — the dump requires significant elevation to work
!Rotating without driving forward, so the opponent hops away instead of falling
!Letting the captured leg drop during the rotation, losing all your leverage
!Trying to dump a crouching opponent who has lowered their center of gravity — switch to a trip
!Head too far from their body during the rotation, losing control
!Only rotating in one direction — practice dumping to both sides
