Tough one today…
What Texas minor league baseball team won six consecutive league titles in the 1920s?
The Texas Tornados 
hmm. never heard of them and i spent some years touring some minor league teams. toledo mudhens got a lot of publicity from mash but they live up to it during the game, much better game atmosphere than mlb parks i have been to.
The Fort Worth Cats
Founded in 1888 as the Fort Worth Panthers, the team won the Texas League a dozen times between 1905 and 1958, including a streak of six consecutive titles from 1920. Before their dissolution in 1964, the Cats were affiliated with the Detroit Tigers, Cincinnati Reds, Brooklyn Dodgers, and Chicago Cubs. Another iteration of the team played in Fort Worth from 2001 to 2014
