1866 June

16th  At Morrisania, the Union Club defeats the Enterprise Club of Brooklyn by the score of 42–16. The Unions led all the way and, according to the New York Times, “did some tall batting after the third inning. The fielding of the Enterprise nine was very loose, while the Unions, although, they were short Abrams at third and Austin at right, fielded very well. The attendance was quite large, the belles of Morrisania gracing the scene with their presence in unusual numbers. At the conclusion of the game the Brooklyn boys were nicely entertained by the victors.”

12th Leading 26–22 going into the 9th inning at Morrisania, the visiting Eureka Club of Newark seem headed for their 3rd straight win over the Unions. But the Unions rally for 6 runs and win, 28–26.
