One of the classic cases of a rags to riches story in the baseball world is that of Pedro Martinez. Born in the Dominican Republic town of Manoguayabo, Martinez went on to become one of the most prolific pitchers to ever play in the MLB. He holds some of the best records in the league and is regarded as one of the legends of the sport.
Born into an impoverished family, he used to practice with an orange before being spotted by a scout at a Los Angeles Dodgers training camp. From there, he went on to sign for them on an amateur fee in 1988.
