It was the home of the Toledo Mud Hens and their predecessors from 1897 until mid-season 1909 when Swayne Field opened.
That book does not give specific dimensions but states that right-field was so short that fly balls hit over the fence in that area were ground-rule doubles.
The lot between Beech and the Armory was the location of the ballpark, precisely where the current U.S. District Courthouse now stands.
The final game at Armory Park was played on July 2, 1909, the day before Swayne Field's debut.
(Toledo Baseball Guide, p. 98) The Armory building itself was destroyed by fire in 1934, in connection with rioting in the Auto-Lite strike.
