The Eureka club of Newark were the dominant team in the 1870s American Association, winning four AA pennants and four American Cups. Moving up to the National in 1880, the Eurekas were a perpetual top-half club, making five Centennial Cup playoff appearances and a Cup Final in 1886. In 1890, though, Newark tumbled to 19th place and had to ply their trade in the AA in 1891.
Well, they're headed back to the National in 1892, after winning the AA pennant and sweeping out the Pilgrims in four straight:
The Union Cup Final was more compelling. The teams split two games in Dayton and two more in Quebec; in Game 5, Harry Stovey socked a three-run homer in the third and Montreal was never headed, winning, 6-3. But back in Welcome Stadium in Dayton, the Veterans evened things up in Game 6. Tied at 4 in the bottom of the seventh, after two errors and walk loaded the bases, Dayton's Barney Gilligan was hit by a Hank Gastright pitch to make it a 5-4 game; it ended 6-4, forcing a Game 7.
In Game 7, five Dayton errors doomed the Veterans as Montreal scored three in the top of the first and went on to win, 9-3, and clinching the Union Cup!
