The 2019 World Series was the championship series of Major League Baseball's (MLB) 2019 season. The 115th edition of the World Series, it was a best-of-seven playoff between the American League champion Houston Astros and the National League champion Washington Nationals. The series was played from October 22 to October 30. The Nationals won the series, four games to three, to secure their first title in franchise history. Washington pitcher Stephen Strasburg was named the World Series Most Valuable Player (MVP) after earning two wins in the series.
The Astros had home-field advantage for the series, due to having a better regular-season record than the Nationals. It was the third World Series in which home-field advantage was decided by the regular-season records of the American and National league champions, a practice that started in the 2017 season. It was the first World Series in which the Houston Astros had home-field advantage. The series was played in a 2–3–2 format, with the Astros hosting Games 1, 2, 6, and 7; and the Nationals hosting Games 3, 4, and 5.
The visiting team won all seven games for the first time in any of the major North American sports leagues, surpassing the previous high of five. It was also the sixth straight World Series in which the championship was clinched by the visiting team.
With the Nationals being from the National League East division the past six World Series winners have come from each of the six divisions in Major League Baseball. The NL East (2019 Nationals) The AL East (2018 Boston Red Sox) The AL West (2017 Houston Astros) The NL Central (2016 Chicago Cubs) The AL Central (2015 Kansas City Royals) and the NL West (2014 San Francisco Giants)
