Joe Borden of the Boston Red Caps gets the first win in the first game ever played in the National League

Three thousand fans attend the Philadelphia Athletics’ 6-5 loss to the Boston Red Caps in the first game ever played in the National League. The Athletic Park contest becomes the new circuit’s inaugural event by default when the other scheduled games are rained out.

The Alleghenies bring professional baseball to what is now Pittsburgh playing their first game at Union Park. Next year, the team will be accepted into the minor-league International Association but will disband in 1878.
