4) MLB tenth ranked and Texas Rangers’ seventh top prospect is first baseman Ronald Guzman. Standing at 6’5” and weighing 205 pounds at only 19-years old, Guzman has an imposing presence at the plate. He has raw power with the bat and can hit line drives all over the field. He moved to first base because of his lack of speed and below-average arm. With Prince Fielder at first and Mitch Moreland in arbitration, there might be a spot for Guzman as the Rangers DH.
