In his first two full seasons, Clemens became only the fourth pitcher ever to win back-to-back Cy Young awards, pitching 18 shutouts in his first 139 starts. He also established a major league record with 20 strikeouts in a nine inning game, a feat he repeated a decade later. Clemens went on to win an additional three Cy Young awards, bringing his total to an unprecedented five and counting. In the neck of the jersey is the "Wilson" label and size "50."
