The Eureka club of Newark lapped the American Association field in 1878, winning the pennant by a whopping thirteen games!
Meanwhile, New Haven made their first post-season appearance, while their Connecticut neighbors from Middletown lost a one-game playoff to Baltimore for the final spot.
In the playoffs themselves, the Resolutes made it an all-New Jersey final (again) by downing the Marylands, 3-2 and routing the Eckford club of Brooklyn (also making their first American Cup showing), 10-3.
The Cup Final was another thriller. The lead went back and forth, and Sam Armstrong's two-run double off Pud Galvin tied the contest at 6 in the top of the ninth. Hal Brown proved to be the hero in the bottom of the frame with a double off the wall to deliver the American Cup to Newark for the fourth time!
