[citation needed] Losing two of their eight clubs mid-season, the RGVL folded after the 1950 campaign, and four of the loop's teams moved to the Class B Gulf Coast League (not to be confused with the current circuit of that name).

In 1951, Laredo finished fourth but were eliminated by Corpus Christi Seahawks in the post-season; in 1952, the Apaches slipped to fifth and missed the playoffs.

In their final campaign in 1953, led by batting champ Juan Senties (.379), Laredo edged back up to fourth, but were again dumped in the playoffs, this time by Galveston.

In 1995, however, the Owls suddenly had competition, as the San Antonio Tejanos of the independent Texas–Louisiana League transferred to Laredo.

The Lemurs withdrew from the AA before the 2017 season, but the Mexican League announced that the Rojos del Águila de Veracruz club would become a new version of the Owls, and would play some of their home games at Uni-Trade Stadium, starting in 2018.
