Tate comes forward with an onslaught of punches and Rousey uses the champs own weight to get the judo throw. Only takes seconds for Rousey to get the armbar and its torquing back dangerously. Tate gets her leg over the head of Rousey and escapes. Tate land a big left hook and shortly after Rousey gets the judo throw and gets the back and starts to pound her out  and transitions to the armbar and gets the finish with some painful torquing of the arm that looks to have broken it back.
