Morton compiled an 18-11 record for the Expos in 1970 and was voted NL Rookie of the Year. He began as an outfielder in the Braves organization, became a success when converted to the mound, and was taken by the Expos in the 1968 expansion draft. After he slipped to 7-13 in 1972, Morton was traded back to Atlanta, where he strung together three winning seasons for mediocre Braves teams. He won only four games in 1976 and finished in the minors. Morton was only 39 when he died of a heart attack after jogging.
