- May 2 – Rookie Mike Mansell of the newly formed Troy Trojans, in attempting to break up a double play, sprains the neck of star player Ross Barnes of the Cincinnati Reds. As this is not yet an accepted style of play, Mansell is censured for his actions.
- May 17 – With no available regular catchers, the Cleveland Blues (NL) give Fred Gunkle a try. Midway through the game, after 3 errors and 7 passed balls, Gunkle is mercifully moved to right field. It is the only game he will ever play in the majors.
- May 20 – After catcher Pop Snyder cuts his hand in the 8th inning, Boston Red Caps pitcher Tommy Bond is forced to ease up on his pitching. The Chicago White Stockings take advantage of the slower speed and score 4 in the 9th to beat the Red Caps 9–5.

- June 14 – Silver Flint of the Chicago White Stockings hits a ball over the left field fence in the 9th inning against the Troy Trojans. Flint chooses to stop at third base for a triple so that the catcher will have to play closer to the batter, thus giving him a better hitting opportunity.

- July 4 – In a game billed as the championship of the United States, The New York Blue Stockings women's team defeat the lady Philadelphia Red Stockings 36–24 in front of 5,000 fans in Philadelphia.

- July 26 – Syracuse Stars pitcher Harry McCormick hits a home run in the first inning against Boston Red Caps pitcher Tommy Bond and then proceeds to shut out the Red Caps 1–0. It is the only time in major league history that a pitcher has hit a first-inning home run to win a 1–0 game.
