AA's number one key to this fight is to not get overaggressive and get caught reaching in for a punch. Sylvia's key is to keep AA at bay with crisp punches until he can get an opening to attack.
Since Sylvia didn't correct his lazy jab after losing, I highly doubt he will do it after winning. So I think it is going to work out this way. They will feel each other out for a few moments and then Sylvia will throw a lazy jab and AA will knock him down (just like in both previous fights) and then AA will try to take top position and sub him.
