The Straight Ankle Lock Entry from Grasshopper Guard exploits the inverted positioning to capture the opponent’s ankle before they can clear your legs or establish a passing sequence. From the grasshopper configuration, your elevated hips and active leg engagement create natural pathways to thread under the opponent’s lead leg and isolate the ankle joint for a straight footlock attack.
This entry capitalizes on the opponent’s standing posture above your inverted guard. When they commit weight forward or step into your leg range, you shoot your outside leg across their hip line while the inside leg hooks behind their far knee, creating the figure-four clamp necessary for ankle lock control. The transition leverages the same hip elevation mechanics that make grasshopper guard dangerous for sweeps, redirecting that energy into limb isolation rather than positional reversal.
Strategically, the Straight Ankle Lock Entry serves as the primary submission-oriented exit from grasshopper guard when sweep opportunities stall. It pairs naturally with kneebar attacks from the same position, forcing the opponent to defend both the knee and ankle simultaneously. Against opponents who stand tall and wide to neutralize your sweeping game, the ankle lock entry punishes their conservative posture by attacking the most exposed target - the lead foot planted closest to your inverted body.

Playing as Attacker
Key Principles
-
Use hip elevation from grasshopper to generate the lateral movement needed to capture the ankle
-
The outside leg crosses the opponent’s hip line first to block their retreat before the inside leg secures the hook
-
Maintain shoulder contact with the mat throughout the entry to preserve your base and rotation ability
-
Grip the ankle before committing to the figure-four leg configuration - premature leg entanglement without grip control allows easy extraction
-
The entry and the control are one continuous motion - any pause between capturing the ankle and establishing the lock position allows the opponent to clear their foot
-
Timing the entry to the opponent’s forward weight shift dramatically increases success rate compared to attacking a retreating opponent
-
Keep your hips turned toward the captured leg rather than staying flat on your back, which creates the proper finishing angle
Execution Steps
-
Identify the target ankle: From grasshopper guard with hips elevated, identify which of the opponent’s feet is closest to your …
-
Shoot outside leg across hip line: Drive your outside leg (the leg furthest from the target ankle) across the opponent’s hip line, plac…
-
Thread inside leg behind far knee: Simultaneously thread your inside leg (closest to target ankle) behind the opponent’s far knee, hook…
-
Capture the ankle with both hands: As your legs frame the opponent’s lower body, reach both hands toward the target ankle. Your near ha…
-
Close the figure-four leg clamp: With the ankle secured in your hands, close your legs into a tight figure-four configuration by tria…
-
Hip escape to finishing angle: Execute a small hip escape away from the captured leg, turning your body perpendicular to the oppone…
-
Establish Straight Ankle Lock Control: Pull the captured ankle tight against your chest with your forearm blade positioned across the Achil…
Common Mistakes
-
Attempting the entry without sufficient hip elevation, reaching for the ankle while flat on the mat
- Consequence: Without elevated hips, your legs cannot generate the lateral reach needed to frame the opponent’s lower body, and the entry stalls before the ankle is captured. The opponent easily steps away or initiates a pass
- Correction: Engage your core to drive hips to chest height before initiating the entry. Your legs must be at the opponent’s hip level to effectively cross their hip line and thread behind the knee
-
Committing both legs to the figure-four before securing the ankle grip with your hands
- Consequence: If you lock your legs around the opponent’s leg without controlling the ankle, they can simply pull their foot free and you are left in a compromised inverted position with both legs committed and no offensive threat
- Correction: Always establish the two-handed ankle grip first, then close the figure-four. The grip is the primary control; the legs reinforce it. Reverse order leads to positional failure
-
Failing to turn hips toward the captured leg after establishing control, staying flat on back
- Consequence: A flat back position provides no finishing angle for the ankle lock. The forearm cannot properly align across the Achilles tendon, and the opponent can rotate their knee inward to relieve submission pressure
- Correction: After securing the figure-four, immediately hip escape to angle your body perpendicular to the trapped limb. Your belly button should point toward the opponent’s trapped knee
Playing as Defender
Key Principles
-
Deny the entry early by managing distance and base width - staying outside the attacker’s leg range eliminates the attack before it begins
-
Recognize the outside leg crossing your hip line as the first actionable warning sign and immediately back step or circle away from that leg
-
Grip fighting on your own ankle is the highest-priority defensive action once the attacker’s hands reach your foot - strip the grip before the figure-four closes
-
Never allow your lead foot to remain stationary and weighted when the opponent’s hips are elevated in grasshopper - shift your weight to the rear foot and retract the lead foot preemptively
-
Forward pressure through a stack pass is the strongest counter when the attacker commits to the entry, collapsing their hip elevation and folding their inverted base
-
Maintain awareness of the kneebar chain attack - defending the ankle lock by pulling your knee to your chest can expose the knee if the attacker transitions upward
Recognition Cues
-
The attacker’s hips suddenly elevate higher than normal from their grasshopper position and their legs begin moving laterally rather than vertically, indicating they are switching from sweep mechanics to leg capture mechanics
-
The attacker’s outside leg shoots across your hip line toward your far hip, creating a barrier that blocks your ability to step backward - this is the first physical contact of the entry sequence and the earliest intervention point
-
Both of the attacker’s hands release any existing grips and reach toward your lead ankle simultaneously, indicating they are transitioning from positional control to submission-oriented ankle capture
-
The attacker’s inside leg begins threading behind your far knee while their outside leg is already across your hip - this two-leg framing action signals the entry is past the initial stage and moving toward figure-four consolidation
Defensive Options
-
Back step and circle away from the attacker’s outside leg the moment it shoots across your hip line, removing your lead foot from their capture range before the inside leg can complete the frame - When: Immediately when you feel or see the outside leg crossing your hip line - this is the earliest and highest-percentage defensive window before any grip or entanglement is established
-
Drive forward aggressively with a stack pass, dropping your weight onto the attacker’s inverted torso to collapse their hip elevation and fold their body before the entry sequence can complete - When: When the attacker has committed their legs to the framing sequence but has not yet secured the ankle grip - their leg commitment means they cannot easily abort and recover guard
-
Strip the attacker’s ankle grip with a two-on-one grip break, using both hands to peel their near hand off your heel while simultaneously pulling your foot toward your body and curling your toes - When: When the attacker has secured an initial grip on your ankle but the figure-four leg configuration is not yet fully closed - this is the last reliable defensive window before full control is established
Position Integration
The Straight Ankle Lock Entry is the primary submission-oriented exit from Grasshopper Guard, complementing the position’s sweep-based attacks like the Grasshopper Sweep and elevation sweeps to X-Guard. Within the broader leg lock system, this entry feeds directly into Straight Ankle Lock Control, where the finish or further advancement to Inside Ashi-Garami or Outside Ashi-Garami becomes available. It pairs naturally with the Kneebar from Grasshopper as a high-low chain attack, forcing the opponent to simultaneously defend both the ankle and the knee. For practitioners who use grasshopper guard as a transitional hunting position, this entry represents one of two primary attack vectors (ankle lock and kneebar), making it essential for any grasshopper-based offensive game plan.
