The Sophomore League was a class D league that ran from 1958-61. It had previously been known as the Southwestern League. The name change was part of a systemic change. The circuit went from being one with almost no ties to major league baseball and composed of minor league veterans to a league where every team was the farm club of a major league team and prospects of varying quality appeared.

The last Southwestern League was a class B loop that ran just two seasons, 1956 and 1957. The league continued moving south and west, with the focus here around New Mexico and Texas. It had formerly been called the Longhorn League (1947-1955), and would be renamed the Sophomore League (1958-1961). Like its predecessor, it was an offense-oriented leagues where ERAs under 3.50 were very rare. In '56, lifelong minor leaguer Len Tucker hit .404 with 51 homers and 181 RBI, for instance.

The Longhorn League was a high-offense league that ran from 1947 through 1955. In '56, it was renamed the Southwestern League. A league with few prospects (only three teams were ever affiliated with major league clubs, all for one year only; the top teams were farm clubs of other minor league teams), it was home to some long-time minor leaguers who were no longer of interest to major league teams. Even by class C standards, the average talent level was nothing impressive. In two of the league's nine seasons, a Longhorn player posted the top average in the minors - Jim Prince in '47 and Tom Jordan in '55. A .400 average or .700 slugging in this circuit was nothing to write home about. The league is most famous for Joe Bauman's setting the all-time minor-league home run record in '54 with 72 long balls.
