The Dillas were a strong team in the early years of the Texas–Louisiana League, claiming the regular season champion title in 1995, 1998, and 2000.

A neglected stadium and erosion of local fan support resulted in the Dillas being dropped from the Central League following the 2004 season in favor of the El Paso Diablos.

The Amarillo Dillas were brought back in 2006 as one of six charter members of the independent United League Baseball (ULB).

The new Amarillo Dillas management renovated the entire stadium, including a new field and new seats.

Amarillo would continue their success in 2009 with a 44–35 record and another championship, defeating San Angelo for the title.
