Do you know the History between the Giants and Baltimore? Back in the early 1900s the original Baltimore Os who are now the NY Yankees got mad at the NY Giants for stealing their players. They went up to MLB and asked to move to NY. The only ones who disagree were the Giants. The O's end up moving to NY and later change their name to the Yankees. Their goal in life was to make the Giants life hell. In the early going they failed, but when they started winning, well you know the rest. The Giants and Dodgers end up leaving NY and here we're are :)
