The Washington Nationals are an American professional baseball team based in Washington, D.C.. They compete in Major League Baseball (MLB) as a member of the National League (NL) East division. From 2005 to 2007, the team played in RFK Stadium while a new stadium was being built. In 2008, they moved in to Nationals Park, located on South Capitol Street in the Southeast quadrant of D.C., near the Anacostia River. The Nationals are the eighth major league franchise to be based in Washington, D.C., and the first since 1971. The current franchise was founded in 1969 as the Montreal Expos as part of a four-team expansion. After a failed contraction plan, the Expos were purchased by MLB, which sought to move the team to a new city. Washington, D.C. was chosen in 2004, and the Nationals were established in 2005. While the team initially struggled after moving to Washington, the Nationals had considerable success throughout the 2010s. The team had two back-to-back first overall picks in the MLB draft in 2009 and 2010, where they drafted Stephen Strasburg and Bryce Harper. The Washington Nationals secured their first playoff berth and first division title in 2012. They won the National League East again in 2014, 2016, and 2017, but failed to advance past the NLDS each time. In 2019, the team advanced to the World Series and defeated the Houston Astros in seven games to earn their first championship. As of 2021, the franchise’s overall win – loss record is 4,068 – 4,280.
