Playing for the San Francisco Giants most of his career, Marichal was known for his high leg kick, pinpoint control and intimidation tactics, which included aiming pitches directly at the opposing batters' helmets. Marichal also played for the Boston Red Sox and Los Angeles Dodgers for the final two seasons of his career. Although he won more games than any other pitcher during the 1960s, he appeared in only one World Series game and he was often overshadowed by Sandy Koufax and Bob Gibson in post-season awards. Marichal was inducted into the Baseball Hall of Fame in 1983.
