Subway Series (1921)

“The Brooklyns wouldn’t be ahead of the Giants in the Subway series had they played much of the inept and wooden games they played yesterday.” William B. Hanna, New York Herald, September 11, 1921, p45

“Had the Giants come through in the National, interest in the series would be great only in the East where ‘Subway Series’ between the two Manhattan teams are convenient, if nothing else.” James Gould, St. Louis Star and Times, October 3, 1927, p18
