Lang began his career covering the Brooklyn Dodgers for the Long Island Press in 1947. After the Dodgers moved to Los Angeles for the 1958 season, the paper assigned him to cover the New York Yankees. Lang began covering the New York Mets in their inaugural 1962 season, continuing that beat until he retired in 1989. When the Long Island Press folded in 1977, Lang moved to the Daily News. He was the 1986 recipient of the J. G. Taylor Spink Award for "meritorious contributions to baseball writing."
