This is an old Alex Speier article from June of 2010. Written on the occasion of Felix Doubront's major league debut, it has not lost any relevance now that he has made 2012's starting rotation.
The main point of the article is that "Doubront became the first player signed under GM Theo Epstein as an amateur out of Latin America to reach the majors in Boston." After nearly eight years on the job, Epstein and his director of international scouting Craig Shipley finally had a feather in their cap and an example to show other Latin players in the program.
Since then, Doubront has been followed by Yamaico Navarro and Jose Iglesias. Of course, Iglesias is still a minor leaguer hoping to mature into a big-league starter, while Navarro is currently a bench player for the Pittsburgh Pirates. So, having once been the first amateur signee from Latin America in the Epstein/Shipley era to debut in the big leagues for Boston, Felix Doubront is now the first to become a starter.
Upon becoming GM this winter, Ben Cherington fired Craig Shipley as director of international scouting. He was replaced in-house by Eddie Romero, Jr., formerly the assistant director of Latin American operations and international scouting.
