It was called Turnpike Stadium...
I remember attending a Spurs game there. But I sort of remember the team being referred to, wrongly but fairly commonly, as the "Turnpike Spurs" more than the "DFW" Spurs as the text next to the photo at your provided link states that team was named.
They were part of the White Sox farm system? Triple A? Someone correct me if I'm wrong.
I do remember 'ol gravel-voiced Tom Vandergriff. He did quite a bit for Arlington. Elected back when folks were still arguing over para-mutual horse racing (which had many years ago taken place not too far from where the stadiums are now). More out towards where the failed Six Flags Mall is (was? have they torn it down?) but not quite that far East.
