As a reminder, the team with the best regular-season winning percentage, regardless of postseason seeding, will host the World Series. That change was implemented back in 2017 following a run (2003-16) of home-field advantage going to the league that won the All-Star Game.
Prior to 2003, home-field advantage alternated between the AL and NL champions yearly. The 2020 World Series between the Los Angeles Dodgers and Tampa Bay Rays was played at a neutral site (Globe Life Field, home of the Texans Rangers) due to the COVID-19 pandemic.
As was the case last season, the best remaining team in terms of record will kick off the World Series at home.
