The Los Angeles Dodgers were the last to win the World Series in 2020, they won against the Tampa Bay Rays in just six games, the seventh game was not necessary as the Dodgers had one more game advantage over the Rays.
The last world series has been played like the rest of the other championships with the best-of-seven format, the team that wins the most of the seven games will be crowned the champion of the season. Rarely does a team win 4-0, but in the last World Series the Dodgers' lead over the Rays was clear.
Last season in 2020 was a bit shorter than normal but the World Series retained its best-of-seven games format for the championship. Another important piece of information from the last World Series that was affected by Covid-19 was that all the games were held in a single stadium, at the home field of the Texas Rangers.
