"While minor league pitchers can only dream of being able to locate four distinct pitches in any given outing, it was important for us to see the importance Nolasco placed on his pitch selection and location." makes me wonder: if true, how do minor league pitchers ever transform into major league pitchers? do they advance to the majors without being able to locate four distinct pitches and then acquire the ability once there? or is this comment some degree of hyperbole?
