Overhand Slide To Rear Mount
Joseph Garza has donated this and other techniques from his site at Josepgh Garza's Submission Page Stop by site and check it out. Here, Joseph demonstrates the 'Overhand Slide To Rear Mount'
In the stand up.
My opponent steps forward with his right. This could be a strike or tie up attempt. Block with the outside of your left forearm. Place your left hand outside of his right bicep.
Extend your left forearm until it is pressed on the back of his elbow.
Grab above the back of his elbow with your right hand (over hand grab no thumb).
Pull his tricep past your right leg towards the ground. Wrap your left arm around your opponent's waist.
Under hook both armpits and swing behind for the rear mount position.
