We probably can agree that none of the six intramural rivalries we have in New York City in 2015 can come close to the boiling, broiling resentments that festered from 1903 through 1957, when the Yankees, Dodgers and Giants shared the city and divided loyalties so fiercely fans were occasionally moved to violence and players to fury.
No exaggerations there, either. On the evening of July 12, 1938, a Giants fan named Frank Krug strolled into a tavern at the corner of Ninth Street and Seventh Avenue in Brooklyn called Pat Diamond’s Bar & Grill. There he encountered a Dodgers fan named Robert Joyce.
