Nicknamed "Rocket", Roger Clemens played 24 seasons for four teams. Clemens was one of the most dominant pitchers in major league history, tallying 354 wins, a 3.12 ERA, and 4,672 strikeouts, the third-most all time. An 11-time All-Star and two-time World Series champion, he won seven Cy Young Awards during his career, the most of any pitcher in history. Clemens was known for his fierce competitive nature and hard-throwing pitching style, which he used to intimidate batters.
