Clay Palmer Carroll (born May 2, 1941 Clanton, Alabama) is a former relief pitcher with a 15-year career in Major League Baseball from 1964 to 1978. He pitched for the Milwaukee Braves & Atlanta Braves, Cincinnati Reds, St. Louis Cardinals, and Pittsburgh Pirates - all in the National League - and the Chicago White Sox of the American League.
Carroll, nicknamed "the Hawk," was selected to the National League All-Star team in 1971 and 1972. He led the National League in saves in 1972 with 37, and finished tied for fifth in the Cy Young Award voting that year. The 37 saves stood as a National League record until Bruce Sutter broke it in 1984 with 45 saves pitching for the St. Louis Cardinals.
Carroll's best seasons were with the Reds, for whom he pitched from 1968 to 1975, earning him a place in the Cincinnati Reds Hall of Fame.
Carroll pitched in three World Series for Cincinnati, including the 1975 World Series in which the Reds beat Boston four games to three. Carroll starred in the 1970 World Series against Baltimore as he appeared in five of the six games, hurling 9 shutout innings with 11 strikeouts to buoy a staff that otherwise struggled with injuries and ineffectiveness. Carroll was the winning pitcher in the Reds' only victory against the Orioles. Overall, Carroll had a stunning 1.39 ERA in 22 postseason appearances, allowing just five earned runs in 32.3 innings.
