The Texas League used to be based around the entirety of the "Big State" but that has lessened significantly in past years with the addition of T.L. teams in Springfield Missouri, 2 in Arkansas and another in Tulsa. The 8 team Texas League features only 4 teams from the actual state of Texas and 3 of those are east of the I-35 line which runs from Dallas to San Antonio. Midland represents not just Midland, but all of Central to Western Texas. (El Paso once joined Midland in that category but they're now in the Triple-A Pacific Coast League).
