The Houston Astros are an American professional baseball team based in Houston, Texas. The Astros compete in Major League Baseball as a member club of the American League West division, having moved to the division in 2013 after spending their first 51 seasons in the National League. The Astros were established as the Houston Colt .45s and entered the National League as an expansion team in 1962 along with the New York Mets. The current name, reflecting Houston's role as the host of the Johnson Space Center, was adopted three years later, when they moved into the Astrodome, the first domed sports stadium and the so-called "eighth wonder of the world." The Astros moved to a new stadium called Minute Maid Park in 2000. The Astros played in the NL West division from 1969 to 1993, then the NL Central division from 1994 to 2012, before being moved to the AL West as part of a minor realignment in 2013. The Astros posted their first winning record in 1972 and made the playoffs for the first time in 1980. The team made its first World Series appearance in 2005 as an NL team, only to be swept by the Chicago White Sox.
