Roger Clemens is a former professional baseball player who is widely regarded as one of the greatest pitchers of all time. He played for several teams during his career, including the Boston Red Sox, Toronto Blue Jays, New York Yankees, and Houston Astros.

Clemens was known for his powerful fastball, which he could throw at speeds of up to 100 miles per hour. He also had a devastating splitter and a slider that he used to keep batters off balance. His aggressive style of pitching earned him the nickname "Rocket."

Clemens won seven Cy Young Awards during his career, which is more than any other pitcher in history. He also won two World Series championships, one with the Yankees in 1999 and another with the Astros in 2005.

Despite his success on the field, Clemens was not without controversy. He was accused of using performance-enhancing drugs during his career, which he vehemently denied. He was later indicted on charges of perjury and obstruction of justice for lying to Congress about his alleged drug use. He was acquitted of all charges in 2012.

Despite the controversy, Clemens remains one of the most dominant pitchers in baseball history. He finished his career with a record of 354 wins and 184 losses, with a career ERA of 3.12. He also struck out 4,672 batters, which is the third-highest total in history.

Clemens was inducted into the Baseball Hall of Fame in 2018, after several years of being passed over due to the allegations of drug use. His induction was controversial, with some arguing that his alleged drug use should have disqualified him from the honor. However, many others believe that his on-field accomplishments were enough to earn him a place in the Hall of Fame.

Overall, Roger Clemens was one of the most dominant pitchers in baseball history. His powerful fastball and aggressive style of pitching made him a feared opponent for batters, and his seven Cy Young Awards are a testament to his greatness. While his career was not without controversy, his on-field accomplishments cannot be denied.
