Clemens, one of the all-time elite pitchers, has seen his Hall of Fame candidacy hurt by suspicions that he used performance-enhancing drugs.
A player needs 75 percent of the votes to receive entry to the Hall of Fame. This year, 332 votes represented the magic number. Tim Raines, Ivan Rodriguez and Jeff Bagwell were elected.
Bagwell was a Red Sox prospect who was traded to the Astros for veteran reliever Larry Andersen in 1990.
Clemens was at the height of his dominance in Boston at that time, and would later play with Bagwell in Houston.
