 Between the dumping of star players by the Philadelphia Athletics and the Red Sox, and the decimation of the White Sox, a "power vacuum" was created in the American League, into which the Yankees would soon move.The White Sox finally became competitive again under popular manager Jimmy Dykes, who led them from 1934 to 1946 – still the longest managerial tenure in team history.However, the White Sox did not completely recover from their malaise until the team was rebuilt in the 1950s under managers Paul Richards, Marty Marion, and Al López.
