Americana

The keylock shoulder lock

The Americana is a shoulder lock applied from a dominant top position — side control or mount — where the attacker rotates the opponent's arm forward (toward the opponent's head) to attack the rotator cuff and shoulder ligaments.

It's the mirror-image submission to the kimura: same shoulder mechanics, different rotation direction. The Americana is one of the most-attempted submissions in MMA grappling but one of the lowest-percentage finishes because the defense (connecting the hands) is well-known and reliable.

Mechanics

From side control with the attacker on the opponent's right side:

• Pin the far arm: the opponent's right arm needs to be in a bent position above their head, with the elbow at 90 degrees.
• Figure-four grip: the attacker's left hand grips the opponent's wrist; the right arm goes under the opponent's right upper arm and grips the attacker's own left wrist.
• Drag the arm down: the attacker drags the opponent's wrist toward the mat, while keeping their forearm in place.
• Finish: the rotation produces shoulder hyperextension. The opponent taps or the shoulder gives.

Setup positions

• Side control top: the most common entry. The far arm needs to be in the L-shape position.
• Mount: rotating the opponent's arm to the L-shape position from mount.
• Crucifix mount: a variation where the opponent's arm is fully trapped.

Common errors

• Wrist grip not deep enough: a shallow wrist grip lets the opponent rotate the wrist out.
• Forearm not perpendicular: the attacker's forearm needs to be perpendicular to the opponent's forearm.
• Insufficient pressure: the Americana requires constant pressure throughout the rotation.
• Loss of position: if the attacker rises too high, the opponent can shrimp out.

Defense

• Connect the hands: locking both hands together prevents the wrist from being isolated.
• Posture and base: from the bottom, maintaining strong arm structure to prevent the L-shape position.
• Shrimp out: hip-escaping out of side control to reset position.

Variations

• Standing Americana: rare but possible from clinch range.
• Mounted Americana: from full mount, attacking the same shoulder mechanics.
• Reverse Americana: a less common variant.

Exemplified by

• Frank Mir: the Americana finish of Tim Sylvia at UFC 48 — a clean side-control Americana that took the heavyweight title.
• Khabib Nurmagomedov: occasional Americana attempts from his top-position ground-and-pound.
• Demian Maia: integrated Americanas with the broader welterweight submission catalog.

Drills

• Position drill: from cooperative side control, drill the Americana entry and finish.
• Defense drill: partner attacks the Americana; you practice connecting hands and protecting the arm.
• Live ground sparring from side control: rounds where the Americana is the primary submission attempt.
