Roger Clemens is a former professional baseball pitcher who played 24 seasons in the MLB for four different teams, most notably the Boston Red Sox and the New York Yankees. Clemens was selected in the first round (19th overall) of the 1983 MLB draft by the Boston Red Sox and quickly rose through the minor league system.

Clemens debuted in the MLB in 1984 with the Red Sox, whose pitching staff he anchored for 12 years. 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 (2020). 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 as of 2020. Clemens was known for his fierce competitive nature and hard-throwing pitching style, which he used to intimidate batters. 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. Prior to the 1999 season, Clemens was traded to the Yankees where he won his two World Series titles.

He rejoined the Yankees in 2007 for one last season before retiring. Clemens was inducted into the Boston Red Sox Hall of Fame in 2014, and was inducted into the Pawtucket Red Sox Hall of Fame on June 21, 2019.
