Fall 2019 Day 20 and Last:
Wednesday 30 October: Washington wins in Houston 6-runs-2 to win the 2019 World Series 4-games-3. The Washington Nationals thus win their first-ever MLB championship, after having begun play as the old Montreal Expos in 1969.

Road Rules I:
With the Washington Nationals victory in 2019 World Series Game 7, road teams now own a six-Game 7 winning streak in MLB/NBA/NHL Finals. Road teams had won 11 of 14 Finals Game 7s (beginning with the 1965 MLB Los Angeles Dodgers and ending with the 1979 MLB Pittsburgh Pirates), but home teams then won 18 straight Finals Game 7s (beginning with the 1982 MLB St. Louis Cardinals and ending with the 2006 NHL Carolina Hurricanes).

Road Rules II:
The Washington Nationals plated 90.9% of their runs in the 2019 World Series on the road - that percentage breaks the MLB record in playoff series lasting the full seven games, set by the Detroit Tigers at 87.5% in the 1945 World Series. In World Series 2019 - the 1418th MLB/NBA/NHL best-of-7 playoff series and the first in which road teams won all seven games - road teams accounted for 77.8% of the scoring (breaking the record of 73.8% in series lasting all seven games, as set in the 1968 World Series won by the Detroit Tigers over the St. Louis Cardinals).

Second-Biggest Upset:
The Washington Nationals in the 2019 World Series tied for the second-largest upset victory in best-of-7 MLB Finals history, having trailed the Houston Astros by fourteen regular-season games. The old New York Giants also trailed the Cleveland Indians by fourteen regular-season games in 1954, but won the 1954 World Series. In the largest such upset, the Chicago White Sox trailed the Chicago Cubs by 22.5 regular-season games in 1906, but won the 1906 World Series.

New Leader:
With an 8-3 (.727) best-of-7 MLB playoff game record through the 2019 World Series, the Washington Nationals now own the highest best-of-7 MLB/NBA/NHL playoff game winning percentage, surmounting the "Anaheim Angels" (after they were the "California Angels" and before they were the "Los Angeles Angels of Anaheim") which under that identifier posted an 8-4 (.667) best-of-7 MLB playoff game record.
