The Houston Astros are an American professional baseball team based in Houston, Texas. They compete in Major League Baseball (MLB) as a member club of the American League (AL) West division, having moved to the division in 2013 after spending their first 51 seasons in the National League (NL). The team was established as the Houston Colt .45s in 1962 and changed their name to the Astros in 1965 when they began playing in the Astrodome. The Astros have played in three ballparks in Houston: Colt Stadium (1962–1964), the Astrodome (1965–1999), and Minute Maid Park (2000–), a stadium with a retractable roof. They have won two World Series titles (2017 and 2022) and five pennants (one in the National League and four in the American League). The team has a reputation as a villain in the league, particularly after a sign-stealing scandal in 2017.
