Steven Norman Carlton is an American former professional baseball player. He played in Major League Baseball as a left-handed pitcher for six different teams from 1965 to 1988, most notably as a member of the Philadelphia Phillies with whom he won four Cy Young Awards as well as the 1980 World Series. He was elected to the Baseball Hall of Fame in 1994 in his first year of eligibility.
Nicknamed "Lefty", Carlton has the second-most lifetime strikeouts of any left-handed pitcher (4th overall), and the second-most lifetime wins of any left-handed pitcher (11th overall). He was the first pitcher to win four Cy Young Awards in a career. He held the lifetime strikeout record several times between 1982 and 1984, before his contemporary Nolan Ryan passed him.
