Samuel Lee Stewart (October 28, 1954 – March 2, 2018) was an American professional baseball player. He pitched in Major League Baseball (MLB) from 1978 to 1987. Stewart had the best earned run average (ERA) in the American League (AL) in 1981 and he pitched in the postseason in 1979 and 1983. He won the American League championship in 1979 and the World Series championship in 1983, both with the Baltimore Orioles. He became addicted to crack after he retired from baseball; this led to a prison term that ran from 2006 to 2013.
