[1][2] In 1955, Amarillo won the regular-season pennant and led the WT-NML in attendance, but it was a Pyrrhic victory, as the league folded for good at the close of the season.
It enjoyed success on the field, winning the 1956 regular-season title, and at the gate, leading the league in attendance in its final season, 1958.
But the Gold Sox disappeared from the baseball map when the 1964 Texas League contracted, and when Amarillo returned to the TL in 1965, it was known as the Sonics from 1965–1967 and the Giants from 1968–1974.
But after only one season without professional baseball, in 1976, the Amarillo Gold Sox returned to the circuit, as the San Diego Padres moved their Double-A farm club from Alexandria, Louisiana.
In 1981 the Gold Sox roster included future major leaguers Tony Gwynn, Mark Thurmond, Andy Hawkins and Dave Dravecky.
