Change Up is a documentary that follows the lives of best friends, Rafael "Pepey" Rodriguez, and Alex Sosa, two hard throwing pitchers from the economically poor, but baseball rich island of The Dominican Republic. The film follows the two teenagers after they have quit school to concentrate full time on being signed by the American Major League teams. The two, along with their agent, go on a year long string of tryouts, impressing Major League scouts with mid 90 mph pitching. The question is, will their lives change forever with the riches that come along with professional sports, or will they be destined to live a life in their home country, asking forever, what if?
