Roberto Enrique Clemente Walker was a Puerto Rican professional baseball right fielder who played 18 seasons in Major League Baseball (MLB) for the Pittsburgh Pirates. After his early death, he was posthumously inducted into the National Baseball Hall of Fame in 1973, becoming both the first Caribbean and the first Latin-American player to be enshrined. Because he died at a young age and had such a historic career, the Hall of Fame changed its rules of eligibility. As an alternative to a player having to be retired for five years before eligibility, a player who has been deceased for at least six months is eligible for entry. Some of his many career highlights include being a 15 time All-Star, a 12 time Gold Glove winner, two time World Series Champion and an NL MVP in 1966.
