Rene Francisco stepped inside the home clubhouse at Kauffman Stadium to say hello to Johnny Cueto on an afternoon in early August, about a week after Kansas City acquired the distinguished right-hander to boost its World Series hopes down the stretch. Next to Cueto sat Edinson Volquez, and next to Volquez sat Yordano Ventura. Francisco, the Royals’ assistant general manager in charge of international operations, has spent the better part of the last 20 years grooming and nurturing starting-pitching prospects in the Dominican Republic.
