Re Richard Eder's review of "Mao II" by Don De Lillo (June 9):
Just to set the record straight, Yankee Stadium is in the South Bronx, not upper Manhattan.
The Polo Grounds, former home of the N.Y. Giants, now in San Francisco, was in upper Manhattan. And, of course, Ebetts Field, home of the Brooklyn Dodgers, was in Brooklyn.
