Star of the late 1960s, Rainbow Guts) and logos many times throughout their history. History The Lone Star Series was the consequence of many things that happened to Texas in the 1950s: population shift westward from metropolitan areas on the East Coast, the space program, more modernized higher education, and the formation of the brief Continental League resulting in expansion in Major League Baseball shortly thereafter. 1962: Texas has its first major league team, the Colt .45s Prior to 1962, there were no Major League Baseball teams in Texas until the Houston Colt .45's of the National League. They played in Colt Stadium for the first three years of existence, fighting against hot and humid weather and outrageously large mosquitoes, which also had an effect on the fans.

They replaced the old Washington Senators who had moved to the Minneapolis–Saint Paul area to become the Minnesota Twins in 1961. The new Senators changed
