A spirited match took place yesterday at the grounds on Eighth and Hickory streets, between the Empire and Hickory clubs. The former proved victors by a score of twenty-eight, to nine for the later.

The location of the ball grounds at Eighth and Hickory is also significant. I don't think I have any other references to what most have been the Hickory's home grounds, which is just a few blocks south of where Busch Stadium currently stands. So this reference gives us both a new club and a new baseball ground.
