Lee Arthur Smith (born December 4, 1957) is a retired American right-handed relief pitcher who played for eight teams in Major League Baseball from 1980 to 1997. A native of Shreveport, Louisiana, Smith was scouted by Buck O'Neil and drafted by the Chicago Cubs in the 1975 Major League Baseball Draft. In his 18-year major league career, Smith's longest tenure with any one team was with the Cubs, with whom he spent his first eight seasons. One of the dominant closers in history, Smith held the major league record for career saves from 1993 until 2006, when San Diego Padres relief pitcher Trevor Hoffman passed his final total of 478 on September 24. Smith was known as an intimidating figure on the pitcher's mound at 6 feet, 6 inches (1.98 m) and 265 pounds (120 kg) with a 95 mile per hour (150 km/h) fastball.
In 1991, Smith set a National League record with 47 saves for the St. Louis Cardinals, and was runner-up for the league's Cy Young Award; it was the second of three times he led the NL in saves, and he later led the American League once while with the Baltimore Orioles in 1994. He also set the major league career record for games finished (802), and his 1,022 career games pitched were the third most in history when he retired; he still holds the team records for career saves for the Cubs (180), and he also held the Cardinals record (160) until 2006. Smith has been a candidate for induction into the Baseball Hall of Fame five times since 2003, but has generally received 37-45% of the necessary votes on all total ballots cast by the Baseball Writers' Association of America, with 75% needed for election. After the end of his major league career, Smith spent time working as a pitching instructor at the minor-league level with the San Francisco Giants. He then served as the pitching coach for the South Africa national baseball team in the 2006 World Baseball Classic and afterwards continued his previous job as a minor-league roving pitching instructor for the Giants.
