23rdThe 1878 St. Louis squad, including Devlin, Snyder and Hall of this year’s Louisville team, beats Boston, 9–1, in an exhibition game.
26th Louisville club vice president Charles Chase confronts George Hall, the HR leader in ’76 with 5, and Jim Devlin with charges that they threw road games in August and September. Both admit to throwing non-league games (an exhibition game in Lowell, MA August 30 and another in Pittsburgh September 3) and implicate teammates Al Nichols and Bill Craver. Hall implicates Devlin saying that the 2 helped in losses to the NL Cincinnati Reds on September 6 and to the minor league Indianapolis Blues on September 24, but he argues that since the Reds were about to be suspended and the games nullified, it amounted to an exhibition game.
27th The Louisville club formally expels Devlin, Hall, and Nichols for selling games and tampering with other players, and expels Craver for “disobedience to positive orders.” Their remaining 1877 salaries, which the Louisville team acknowledged, are “forfeited”. Nichols, the exposed go-between who had been dropped by Pittsburgh (International Association) earlier in the year for trying to bribe pitcher Pud Galvin, left town weeks earlier. Craver will deny any wrongdoing but refused to make public his telegrams. Devlin and Hall received $75.00 and $25.00 respectively in the mails. While this was going on, Devlin forwarded an eviction notice from his landlord to the Louisville club for $150.00, which the team ignored despite owing Devlin $470 salary. Devlin’s testimony also stated that Louisville paid umpire Dan Devinney extra to deliver about 20 victories this year to the team, but Louisville directors said that “that part of Devlin’s testimony was a lie.” After the season rules are changed as to how each team picked umpires for home games (as noted by Frank Vacarro).
31stAt a stockholders meeting, the St. Louis club announces an agreement with the players that will reduce the salaries still owed from $4,389.68 to $2791.46.
