Rusney Castillo's long journey to the major leagues is over. The Boston Red Sox rookie outfielder will make his debut on Wednesday night against the Pittsburgh Pirates. The 27-year-old Castillo will play center field and bat seventh, ending a three-week sprint through Boston's minor league system for the former Cuban star. Castillo insists he feels no pressure to produce the kind of immediate impact in the majors provided by fellow countrymen like Los Angeles Dodgers star Yasiel Puig and Chicago White Sox slugger Jose Abreu.
