Baseball is the economic and cultural lifeblood of the Dominican Republic. The tiny, impoverished island nation has produced some of the games greatest professional players — from Juan Marichal and Miguel Tejada, to Pedro Martinez and David Ortiz.

A new documentary tells the story of Domincan baseball players; of their dreams to cash in and of the way Major League Baseball develops, recruits and signs these young players. The film is called "Ballplayer: Pelotero" and was produced by Red Sox manager Bobby Valentine.

Guest:

"BallPlayer: Pelotero" opens July 13 at the Coolidge Corner Theatre.
