William Roger Clemens (born August 4, 1962), nicknamed "Rocket", is an American former professional baseball pitcher who played 24 seasons in Major League Baseball (MLB), primarily with the Boston Red Sox. Clemens was one of the most dominant pitchers in major league history, tallying 354 wins, a 3.12 earned run average (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, more than any other pitcher in history. Clemens was known for his fierce competitive nature and hard-throwing pitching style, which he used to intimidate batters. Clemens debuted in MLB in 1984 with the Red Sox, whose pitching staff he anchored for 12 years. In 1986, he won the American League (AL) Cy Young Award, the AL Most Valuable Player (MVP) Award, and the All-Star Game MVP Award, and he struck out an MLB-record 20 batters in a single game. After the 1996 season, in which he achieved his second 20-strikeout performance, Clemens left Boston via free agency and joined the Toronto Blue Jays. In each of his two seasons with Toronto, Clemens won a Cy Young Award, as well as the pitching triple crown by leading the league in wins, ERA, and strikeouts. Prior to the 1999 season, Clemens was traded to the Yankees where he won his two World Series titles. In 2001, Clemens became the first pitcher in major league history to start a season with a win–loss record of 20–1. In 2003, he reached his 300th win and 4,000th strikeout in the same game. Clemens left for the Houston Astros in 2004, where he spent three seasons and won his seventh Cy Young Award. He rejoined the Yankees in 2007 for one last season before retiring. He is the only pitcher in Major League history to record over 350 wins and strike out over 4,500 batters. Clemens was alleged by the Mitchell Report to have used anabolic steroids during his late career, mainly based on testimony given by his former trainer, Brian McNamee. Clemens firmly denied these allegations under oath before the United States Congress, leading congressional leaders to refer his case to the Justice Department on suspicions of perjury. On August 19, 2010, a federal grand jury at the U.S. District Court in Washington, D.C., indicted Clemens on six felony counts involving perjury, false statements, and contempt of Congress. Clemens
