I assume their field was by the old dog track but I don't know. It was well before I moved to AZ. I only knew they played there because during game 7 of the 2017 World Series as the Asterisks were cheating their way to their first World Series title, Rick Monday started laughing about how he remembered playing against the Asterisks (then called the Houston Colt 45s) in "beautiful Apache Junction, Arizona" to which Charlie Steiner added, "Yeah, beautiful!" It was hilarious.
