Professor Lucas Lepri shows how to sweep the opponent using the one leg x or x guard. Lucas starts in the de la riva controlling the pants and collar. He pulls the opponent in and then pushes him to the side. The de la riva leg is now circled under the leg so Lucas can pull the opponent’s leg in, up to his shoulder. Lucas reaches over the leg and grips the same side sleeve. He uses his other hand to grip the far side pants. From here, Lucas now pushes the opponent away to sweep and comes up.
