His second punch left no damage to himself, as he'd been punching at his target rather than through it in anticipation of just such an avoidance, so it was no surprise when the girl moved to defend herself. She shot off the ground as his right arm began driving down, but his weight on her stomach and the height of his torso conspired against her. Fast as she was, her reach wouldn't be enough to get over his shoulder and back down to complete her lock while half her torso was still stuck to the pavement, and he would try to grip her right wrist in his left hand, sticking it to his chest and twisting his body clockwise as he did so, putting her free (left) arm to his front where it would be impossible for her to continue her attempt at a lock. From there, his right hand would join the left on her wrist and he would simply fall back and kick his right heel back into her left armpit as his right foot hooked behind her head, pulling with the first and pushing with the second as he twisted her right arm thumb up and levered the arm bar to hopefully either dislocate or outright break the limb.
