The inner outfield wall at Busch Stadium comes tumbling down, with a little shove by Cardinal first baseman Keith Hernandez. The Cardinals had the walls torn down Thursday, moving the home-run distance back to its original 386 feet in left- and right-center field and 414 feet in center. Since it was erected in 1973 to induce more homers, the fence produced just 49 home runs - 23 by the Cardinals and 26 by the opposition.
