1887—Brooklyn broke Cincinnati’s hold on the ABBA flag, outdistancing the Excellents (and also Baltimore and St. Louis, as three teams tied for second) by six games. In the NBBL New York beat Chicago by four games and Buffalo by six.
Baltimore’s Tom Guthrie was the first batting Triple Crown winner, leading the ABBA in hitting (.333), home runs (14), and RBI (105), also becoming the first player to drive in at least 100 runs in a season. Riley Gamble of Indianapolis hit .354 to top all NBBL hitters.
Dick Mundy of Chicago topped the NBBL in ERA at 2.31, while Brooklyn’s Leander Mcnaughton posted a 1.91 mark to lead ABBA hurlers. Buffalo’s Hugh West was the top winner in the Senior Circuit with 33 victories while Leon Gurley of St. Louis topped the Junior with 25.
The second "unofficial' World Series took place. Like last year's exhibition, the games were not officially sanctioned by either league, were played on neutral fields (in Jersey City and Newark), and the series did not produce an actual winner (with each team taking two of the four contests).
Shortly after the season the ABBA's Kansas City franchise declared bankruptcy. The league decided to "stay west" by awarding a team to Milwaukee, which hadn't been represented since the then-NLPBBC abandoned the city after the 1878 season.
