Italian-Americans in New York had not been in much of a flag-waving mood prior to DiMaggio's arrival. By the All-Star break, the rookie had established himself as a wonderful player (.358, 10HR, 60 RBIs), fully justifying the acclaim. But Gehrig was even better (.399, 20 HR, 61 RBIs). He was leading the league in nearly every category, including invisibility.
