After 22 unsuccessful attempts, Cincinnati becomes
the first AA team to defeat an NL team, beating
Cleveland 5-2.
In the first post-season matchup between AA
and NL champions, Cincinnati shuts out Chicago 4-0.
The next day Chicago returns the favor by blanking
Cincinnati 2-0. At this point Cincinnati, under
pressure from the AA, reluctantly cancels the series
to avoid expulsion from the league.
Columbus, which will join the AA in 1883, is officially
incorporated with $5,000 in capital stock.
The Athletics reveal that in their first AA
season they reaped a $22,000 profit, more than
any NL team earned. This helps convince the NL that
the AA is a viable league.
