Well, in the first 4-5 rounds Wlad should jab, and keep Brock away with his reach. But about mid point during the fight Wlad should start firing the big right frequently because Brock is a southpaw and will be easier to hit with the right, and will think twice about coming in because of Wlad's jab. Brok should counter punch and woork the body. When there's an opening, he should hit Wlad in the solarplex. When Wlad keels over nail him in the face with an uppercut with all of his might, and Wlad has a questionable jaw and should go down.
