From 1977 to 2002, the Drillers were the Double-A affiliate of the Texas Rangers. In 2002, Rangers owner Tom Hicks purchased the Shreveport, Louisiana Texas League franchise with the intention of moving the team to Frisco, Texas, a suburban city north of Dallas, Texas. At the time, the Shreveport Swamp Dragons were affiliated with the San Francisco Giants; Hicks cast aside this association and bought out the remaining two years of Tulsa's Player Development Contract. The Drillers then signed a two-year agreement with the Colorado Rockies. After the 2014 season they signed an affiliation agreement with the Los Angeles Dodgers.
