[8] The Astros' victory was marred in 2019 after a league investigation revealed that they had illegally utilized a system to steal signs from opposing teams during their championship season.

However, Commissioner of Baseball Rob Manfred opted against punishing any of the players involved or revoking the Astros' World Series title.

[21] Additionally, by outscoring the Arizona Diamondbacks and Chicago Cubs by a combined 48–19 margin, the Dodgers entered the World Series with the third-best run differential of any pennant winner since the playoff structure was expanded in 1995.

[33] Following the trade, including the regular season and postseason to this point, Verlander had posted a 9–0 win–loss record with a 1.23 earned run average.

It was the third home run to lead off a game in Dodgers postseason history (following Davey Lopes in 1978 World Series and Carl Crawford in 2013 NLDS).

Carlos Correa drove in the Astros' second run of the game on a single in the eighth, ending the Dodgers bullpen's streak of 28 consecutive scoreless innings in the postseason.

Jose Altuve and Correa hit back-to-back home runs off Josh Fields in the tenth inning to put the Astros in the lead.

[72] The Dodgers scored one run in the top of the third inning as Seager grounded into a double play after McCullers loaded the bases with three consecutive walks.

[74][75] Brad Peacock replaced McCullers, completing the final 3+2⁄3 innings with no hits allowed and four strikeouts to earn his first major league save.

[77][79] As a result, Rob Manfred, the Commissioner of Baseball, suspended Gurriel for the first five games of the 2018 MLB season without pay, but allowed him to continue playing in the World Series.

Joe Musgrove relieved Giles and intentionally walked Forsythe to load the bases and allowed a sacrifice fly to Austin Barnes and a three-run homer to Joc Pederson.

Alex Bregman hit a home run off of Kenley Jansen in the bottom of the ninth inning to cut the lead to four, but the Dodgers won the game to even up the series.

[96] In the sixth inning, Taylor tied the game with an RBI double and Seager hit a sacrifice fly to give the Dodgers the lead.

[100] Dodger reliver Tony Watson earned the win, and Joc Pederson tied a World Series record with his fifth consecutive game with an extra base hit.

[105] Springer doubled to open the game and scored the first run on an error by Bellinger, which allowed Bregman to reach second base.

[106] Kershaw pitched four scoreless innings of relief in the game, and in the process, he broke Orel Hershiser's Dodgers postseason record with his 33rd strikeout.

Correa proposed to his girlfriend, 2016 Miss Texas USA winner Daniella Rodríguez, on live television during a postgame interview conducted by Rosenthal.

[110] After this revelation, 14-year veteran Chase Utley watched the film and later reported to Dodgers president of baseball operations Andrew Friedman that Darvish was not giving off any pitch-tipping cues.

Fox broadcast the series in the United States, with Joe Buck serving as the play-by-play announcer, along with John Smoltz as color commentator and Ken Rosenthal and Tom Verducci as field reporters.

[113] Kevin Burkhardt hosted the pregame shows, joined by analysts Keith Hernandez, David Ortiz, Alex Rodriguez, and Frank Thomas.

[114] Outside the United States, MLB International televised the series, with Matt Vasgersian on play-by-play and Buck Martinez doing color commentary.

[116] As a result, some DirecTV subscribers in portions of the Southeastern United States (as well as those in the Toledo market) were unable to watch the World Series.

[120] ESPN Radio broadcast the series nationally in English, with Dan Shulman providing the play-by-play and Aaron Boone serving as color analyst.

Tim Kurkjian and Buster Olney served as reporters for the network, while Marc Kestecher hosted the pre-game and post-game coverage along with analyst Chris Singleton.

Spanish-language coverage was provided by ESPN Deportes Radio, with Eduardo Ortega, Renato Bermúdez, José Francisco Rivera, and Orlando Hernández announcing.

[149] The Astros' win has been seen as a morale boost for the city of Houston, which 9 weeks earlier had suffered tremendous damage due to Hurricane Harvey.

Five players – Jose Altuve, Alex Bregman, Yuli Gurriel, Lance McCullers, Jr. and Justin Verlander – were on both championship teams; furthermore, 2017 Astros pitcher Charlie Morton was on the champion 2021 Braves.

[159] Before the 2019 World Series, several Dodgers reached out to Washington Nationals second baseman Brian Dozier and pitcher Daniel Hudson, who had been with Los Angeles the previous year, to warn them that Houston was elaborately stealing signs.

[160] After the 2019 season, former Houston pitcher Mike Fiers alleged that the 2017 Astros used technology to illicitly steal their opponents' signs and relay it to their hitters.
