- March 4 – At its annual convention being held in Cleveland, the NA adopts a rule change to allow the use of the wrist in the pitching delivery.
- July 6 – Sporting a 22–1 record, Harry Wright takes the Boston Red Stockings on vacation to an island in Boston Harbor.
- July 9 – The Brooklyn Eckfords commit 13 errors in their 15–3 loss to the Troy Haymakers. It is the fewest errors committed by the 0–11 Eckfords in a game thus far this season.
- July 23 – Despite a winning record, the Troy Haymakers disband due to financial problems. Half of the Haymaker's roster will move to the Brooklyn Eckfords, which saves them from dropping out of the NA.
- July 26 – In an emergency meeting, the NA revises their scheduling requirements from 5 to 9 games versus each opponent competing for the championship. This is in response to the number of teams that have disbanded and comes 3 days after the first-division Troy Haymakers had called it quits.
- August 13 – The Middletown Mansfields announce that they have disbanded the club and drop out of the NA.
- August 19 – The Cleveland Forest Citys disband their club after a loss to the Boston Red Stockings. This drops the number of teams still playing in the NA to 6.
- September 1 – Al Thake, left-fielder batting .295 for the Brooklyn Atlantics, drowns in New York harbor after falling from a fishing boat. Thake is the first active major league ballplayer to die. (But Elmer White, active in 1871, had died in winter.)
