George Kell, a two-time American League batting champion, and Walter Alston, who managed the Dodgers for 23 years and won four world championships, were elected yesterday to baseball's Hall of Fame by an 18-man special committee on veterans.

They will be inducted into the hall, in Cooperstown, N.Y., on July 31 along with Brooks Robinson and Juan Marichal, who were elected in January by 10-year members of the Baseball Writers Association of America.

Kell played for the Detroit Tigers, Philadelphia Athletics, Boston Red Sox and Chicago White Sox from 1943 through 1957. He was an excellent defensive third baseman and had a .306 lifetime batting average..

Alston led the Brooklyn version of the Dodgers to their only world championship in 1955 and a pennant in 1956 before the team moved to Los Angeles, where he led it to World Series victories in 1959, 1963 and 1965 . . .
