Langford grew up in Varina, Virginia. He attended Varina High School, where he participated in four sports. He signed with the Pittsburgh Pirates as a free agent in 1973. He made his MLB debut with the Pirates in 1976. Before the 1977 season, the Pirates traded Langford, Tony Armas, Doug Bair, Dave Giusti, Doc Medich and Mitchell Page to the Oakland Athletics for Phil Garner, Chris Batton, and Tommy Helms. In a streak that began on May 23, 1980, Langford pitched 22 consecutive complete games. The streak ended on September 17, when he came within of an inning of another complete game. He then pitched consecutive complete games in his next three starts. Langford led the American League in complete games and innings pitched that year, and also won a career high 19 games for the Athletics. In 1983, Langford was hit by a line drive in his elbow and tore a muscle in the elbow when trying to play through the injury. However, he'd already been in decline before then. Although he reportedly had a sore elbow late in the 1982 season, his lackluster statistics led baseball writer Rob Neyer to wonder if he'd been injured earlier in the season. Neyer estimated that in 1981, Langford threw as many as 129 pitches per complete game, a heavy workload for a young pitcher even then. A's manager Billy Martin has often been criticized for overworking Langford and the other members of the 1981 rotation He had a 4–19 win-loss record from the 1983 through 1986 seasons. He attempted a comeback to baseball in 1988, pitching for the Columbus Clippers, a minor league baseball affiliate of the New York Yankees. The Yankees did not promote him to the major leagues, and he retired after the season. Langford joined the Toronto Blue Jays organization in 1996 as a pitching coach in the minor leagues. He served as a major league pitching coach in 2002. After the 2008 season, the Blue Jays named Langford their roving minor league pitching instructor. The Blue Jays named Langford their major league bullpen coach for the 2010 season. After the 2010 season, he became the Blue Jays' pitching rehab coordinator. He became the pitching coach for the Syracuse Chiefs of the Class AAAInternational League.
