During the pandemic-shortened 2020 season, Barnes appeared in 29 games for the Dodgers, hitting .244/.353/.314 with one homer and nine RBIs. In the postseason, Barnes was the starting catcher for each of Clayton Kershaw's starts and in the World Series caught Walker Buehler as well. He had two hits in three at-bats in the Wild Card Series, two hits in two at-bats in the NLDS and two hits in seven at-bats in the NLCS. In the 2020 World Series against the Tampa Bay Rays, he had two hits in 13 at-bats. In Game 3, he drove in a run with a safety squeeze and also hit a home run, becoming only the second player to do both of those things in the same World Series game, joining Héctor López in 1961. The Dodgers won the World Series in six games with Barnes catching the final out with Julio Urias closing the game.
